Rheological Interactions Between Barium and Sulfate Ions in HPG Fracturing Fluids: New Insights from the Use of Produced Water

Perbandingan pengaruh ion barium (Ba²⁺) dan sulfat (SO₄²⁻) terhadap viskositas fracturing fluid berbasis hydroxypropyl guar (HPG), menunjukkan peningkatan viskositas hingga 30% akibat konsentrasi 150 ppm barium dalam produced water.
Figure 1. Barium and sulfate in produced water exhibit different effects on performance of fracturing fluid.

Utilization of produced water as an alternative in fracturing fluid formulation is gaining increasing attention in the oil and gas industry, particularly amid limited freshwater availability in the field. However, the complexity of the chemical composition of produced water, especially the presence of monovalent and divalent ions, can significantly affect the rheological properties of the fluid, including viscosity, which is a key parameter in the success of hydraulic fracturing. Therefore, a deeper understanding of ion–polymer interactions becomes crucial in designing fracturing fluid which is optimal and applicable.

This study reviews the results of recent research on the effects of barium and sulfate ions on hydroxypropyl guar (HPG)-based fracturing fluid , as well as their implications for the use of produced water in the field.

Utilization of Produced Water in Fracturing Fluid: Challenges and Opportunities

The use of produced water offers advantages in terms of availability and cost efficiency. However, its complex ionic composition can affect the stability and performance of fracturing fluid. Dissolved ions, both monovalent and divalent, are known to play a role in determining fluid viscosity and flow behavior, and therefore require further investigation.

Research Objective: Understanding the Role of Ions in Performance Fracturing Fluids

This study aims to evaluate the effect of divalent ions, particularly barium (Ba²⁺) and sulfate (SO₄²⁻), on the viscosity of HPG-based fracturing fluid . In addition, this study also aims to understand how these ions influence the rheological behavior of the fluid under various operating conditions.

Testing Methodology: Evaluation of HPG Fluid Rheology under Various Conditions

The testing was conducted experimentally using HPG solutions with varying concentrations of barium and sulfate ions. The main parameter observed was fluid viscosity under different shear rate and temperature conditions.

In general, the testing includes:

  • The addition of BaCl₂ and Na₂SO₄ ions up to a concentration of 150 ppm
  • Viscosity measurement using a rheometer at several shear rate
  • Evaluation at 25°C (surface conditions) and 70°C (reservoir conditions)
  • Analysis of polymer hydration time and fluid residue testing

This approach is used to represent actual field conditions.

Figure 2. The addition of 150 ppm Ba²⁺ can increase HPG viscosity by up to ~30% under low-temperature conditions.

Results and Discussion: The Impact of Barium and Sulfate Ions on Viscosity

The results show that the ionic content in produced water has different effects on the rheological properties of fracturing fluid:
Barium Ion (Ba²⁺)
At a concentration of 150 ppm, barium can increase fluid viscosity by approximately 30% at 25°C. However, at 70°C, this effect becomes less significant.
Sulfate Ion (SO₄²⁻)
Sulfate shows a relatively small effect on viscosity, with an increase of around 7% at low temperature, and no significant effect at higher temperatures.
Fluid Rheological Behavior
The fluid exhibits shear thinningbehavior, where viscosity decreases as increasing shear rate.
Fluid Residue
The presence of barium and sulfate ions increases residue levels, but they remain within industry standard limits.

Figure 3. Barium significantly increases viscosity, while sulfate has a minimal effect. However, this effect weakens as temperature increases.

Conclusion: Implications for Fracturing Fluid Design in the Field

This study shows that barium ions have a more significant effect than sulfate ions in increasing the viscosity of HPG-based fracturing fluid , particularly at low temperatures. Meanwhile, the influence of both ions tends to decrease at higher temperatures.

These findings highlight the importance of characterizing ionic composition in produced water as part of the fracturing fluiddesign process to ensure optimal performance under reservoir conditions.

Training HPLC – RID Part 2: Hands-on System Operation and Polymer Sample Analysis

Dokumentasi peserta dan tim Training HPLC–RID Part 2 di Laboratorium EOR ITB yang menampilkan kegiatan analisis polimer menggunakan HPLC Refractive Index Detector untuk aplikasi EOR

Analysis using High Performance Liquid Chromatography (HPLC) with Refractive Index Detector (RID) is one of the important methods in the characterization of chemical EOR such as surfactants and polymers, particularly to support research needs and application of Enhanced Oil Recovery (EOR). Mastery of this method requires not only theoretical understanding but also the ability to operate the instrument and interpret data accurately. Therefore, OGRINDO ITB together with the EOR Laboratory ITB conducted Training HPLC–RID Part 2, which focuses on hands-on practice and comprehensive system operation, including method setup, system operation, and troubleshooting during testing.

Figure 1. HPLC–RID Part 2 training with PT. Berca Niaga Medika and the EOR Laboratory ITB and OGRINDO ITB team.

Hands-on Operation and System Setup of HPLC–RID

Mastery of the instrument does not stop at understanding theory—but at the ability to operate the system directly and interpret its response in real-time.

In this session, the training focused on hands-on operation of the HPLC–RID system comprehensively. Participants started from the initial stage of instrument operation to the analysis running process, emphasizing systematic and safe working procedures.

Figure 2. Hands-on operation of the HPLC–RID by participants, including sample preparation and injection process.

The activities began with:

  • Procedures for turning on the instrument according to the operational sequence
  • Ensuring the system is in a ready condition
  • Recognizing indicators on the software and instrument as signs that the system has started running

Next, participants performed:

  • Checking system readiness before analysis
  • Setting up methods in the software, both for acquisition and data processing
  • Adjusting important parameters such as baseline, retention time, and peak integration

During this process, participants also directly observed the system response to each parameter setting. This is important to understand how parameter changes can affect the resulting chromatogram.

In addition, the training also emphasized conditions that commonly occur during testing, such as unstable baseline yang tidak stabil, noise , or poorly detected peaks. Participants were guided to recognize these symptoms and understand initial handling steps so that the analysis process can continue properly.

This hands-on approach is key to building participants’ confidence in independently operating the HPLC–RID system in a laboratory environment.

Figure 3. Method setup and data analysis process using HPLC software for chromatogram acquisition and interpretation.
Figure 4. Discussion session and direct observation of the HPLC–RID system to understand operational conditions and instrument response.

Hands-on Polymer Sample Analysis

After understanding system operation and method setup, participants then directly applied this knowledge through polymer sample testing to evaluate system performance.

As the main part of the training, polymer samples were tested with several concentration variations to evaluate the RID detector response and the consistency of the analytical method used.

The chromatogram results show that the polymer peak is consistently detected at a retention time of approximately 6.6 – 6.9 minutes, indicating stable system conditions during the analysis.

In addition, an increasing trend in peak area is observed with increasing sample concentration, indicating that the detector response is proportional to the amount of sample tested.
Summary of Polymer Test Results
60 ppm | RT: 6,898 menit | Area: 9.950
80 ppm | RT: 6,910 menit | Area: 12.414
100 ppm | RT: 6,677 menit | Area: 15.431

Figure 5. Chromatogram of HPLC–RID analysis of polymer sample (60 ppm) showing the main peak at a retention time of approximately 6.898 minutes.
Figure 6. Chromatogram of HPLC–RID analysis of polymer sample (80 ppm) showing the main peak at a retention time of approximately 6.910 minutes.

Brief Analysis of Test Results

The test results show that the method used has provided consistent and reliable responses. The relatively stable retention time at each concentration variation indicates that the system conditions were well maintained during the analysis.

On the other hand, the increase in area values in line with concentration indicates that the RID detector is capable of providing a proportional response to the amount of polymer analyzed. This indicates that the method has good potential for use in quantitative analysis.

However, at this stage, a calibration curve has not yet been applied, so the results obtained are still indicative and have not been used for absolute quantification.

Enhancement of Laboratory Analytical Competence

Through this hands-on session, participants gained practical experience in conducting HPLC–RID analysis comprehensively, from system operation to interpretation of test results. Participants also learned to understand the relationship between method parameters, instrument conditions, and the quality of the resulting chromatogram.

This approach not only improves technical skills but also builds analytical capabilities required in research and laboratory testing activities.

Conclusion

Training HPLC–RID Part 2 provides a comprehensive understanding of system operation and polymer sample analysis through hands-on practice. With a combination of instrument mastery, method understanding, and data interpretation, this training is expected to improve analysis quality and human resource readiness in supporting industrial and research needs, particularly in the EOR field.

Analysis of Surfactant Flooding Performance through Capillary Number Using a Modified Micromodel

Presentasi penelitian mengenai analisis kinerja surfactant flooding menggunakan pendekatan modified micromodel pada Simposium IATMI 2022, sebagai bagian dari studi Chemical Enhanced Oil Recovery (EOR) untuk memahami hubungan antara capillary number dan residual oil saturation.

Surfactant flooding is one of the Chemical Enhanced Oil Recovery (EOR) methods that plays an important role in increasing oil recovery by reducing interfacial tension (IFT) and mobilizing oil trapped within the pores of reservoir rock. This study evaluates the performance of two commercial surfactants through the analysis of the relationship between capillary number and residual oil saturation using a modified transparent micromodel approach combined withigital image analysis. This approach provides a deeper understanding of fluid displacement dynamics in porous media during the surfactant flooding.

Figure 1. Presentation of research results on surfactant flooding performance at the IATMI Symposium 2022.

Research Background and Objectives

Surfactant flooding has long been developed as one of the Chemical EOR methods that is effective in improving oil mobility within the reservoir. By reducing the interfacial tension between oil and water, surfactants allow oil that was previously trapped within rock pores to be more easily mobilized and produced.

In laboratory studies, surfactant flooding performance is often analyzed using the Capillary Desaturation Curve (CDC), which describes the relationship between changes in residual oil saturation and capillary number. Capillary number itself is the ratio between viscous forces—which are influenced by fluid viscosity and injection rate—and capillary forces, which are influenced by the interfacial tension between two immiscible fluids.

This study aims to evaluate the performance of two commercial surfactants by analyzing how changes in the capillary number can affect the reduction of residual oil saturation. To increase the capillary number, the value of interfacial tension between surfactants and crude oil was modified until reaching the ultra-low IFT condition, allowing the capillary number to increase by three to five orders of magnitude.

Figure 2. Presentation of research on the evaluation of surfactant flooding performance using a modified micromodel , discussing the relationship between capillary number and residual oil saturation in a Chemical EOR.

Experimental Approach Using a Modified Micromodel

This study uses a transparent modified micromodel that enables direct visualization of fluid movement in porous media. This approach provides a clearer picture of the oil displacement process during surfactant injection.

To represent reservoir conditions more realistically, the micromodel was modified by adding quartz and cement, allowing fluid–rock interactions to be observed more representatively. The experimental process was then analyzed using Digital Image Analysis (DIA) to calculate important parameters such as initial oil saturation, residual oil saturation, water saturation, and surfactant saturation quantitatively.

This study consists of two main testing stages: a static test to evaluate fluid compatibility through CMC–IFT testing, and a dynamic test using the micromodel to directly observe the surfactant flooding process within porous media.

Figure 3. Example of a modified transparent micromodel used in the study to visualize fluid movement in porous media during the surfactant flooding.

Research Results and Insights

The results of the study show that the reduction of interfacial tension between the surfactant solution and crude oil directly influences the reduction of residual oil saturation, which ultimately increases oil recovery.

However, the study also shows that the lowest interfacial tension does not always result in the highest oil recovery . This finding provides an important perspective that an increase in capillary number at a certain level is sufficient to improve oil mobilization, without always having to reach the condition of ultra-low IFT.

The approach using a modified micromodel also demonstrates significant potential as an experimental method that is simpler, faster, and more cost-efficient compared to conventional methods such as coreflood test, while still being able to provide detailed insights into fluid–rock interactions at the pore scale.

Training HPLC – RID Part 1: System Introduction for Precise Analysis

Training HPLC–RID di Laboratorium EOR ITB bersama PT. Berca Niaga Medika yang membahas pengenalan sistem HPLC 1260, diskusi teknis, serta tips operasional untuk analisis kromatografi yang presisi.

In an effort to maintain accurate, precise, and reproducibleanalytical quality standards, OGRINDO ITB and the EOR Laboratory ITB organized an HPLC–RID Training in collaboration with PT. Berca Niaga Medika. This activity aims to strengthen the team's understanding of the High Performance Liquid Chromatography (HPLC) system with a Refractive Index Detector (RID), ensuring optimal instrument operation and generating reliable data to support research and applications of Chemical EOR.

Figure 1. Technical discussion session during the HPLC–RID Training with the team from PT. Berca Niaga Medika at the EOR Laboratory ITB.
Figure 2. Training participants enthusiastically taking part in the discussion and introduction session of the HPLC–RID system at the EOR Laboratory ITB.

HPLC 1260 – RID System at the EOR Laboratory ITB

The EOR Laboratory ITB utilizes an HPLC type 1260 equipped with an RID detector system and a manual injector. This configuration is highly suitable for analyzing compounds such as polymers and surfactants, particularly in studies of chemical adsorption onto rock, detection and quantification of polymers and surfactants in monitoring wells, as well as evaluation of injection performance in Chemical EOR schemes. Understanding each component is key to maintaining system stability and ensuring the quality of analytical results.

Figure 3. The instructor explaining the configuration and main components of the HPLC–RID system used in the sample analysis process.

Main Components and Their Functions

  1. Mobile Phase Reservoir
    A container used to store the solvent (mobile phase) that will flow through the system. The quality and cleanliness of the mobile phase greatly determine pressure stability and the baseline chromatogram.
  2. Isocratic Pump
    The system used is isocratic, meaning it uses a single, constant mobile phase composition throughout the analysis. In contrast, gradient systems allow changes in the composition of 2–4 solvents through softwarecontrol, isocratic systems are simpler and more stable for routine methods with relatively consistent sample matrices.
  3. Manual Injector
    The injection process is carried out manually using a 20 µL loop and a precision syringe (typically 50 µL) to ensure consistent injection volume and repeatability maintain.
  4. HPLC Column
    The column is the core of the separation process. The column compartment is equipped with a heater with temperatures up to 85°C to maintain temperature stability and consistency retention time.
  5. Refractive Index Detector (RID)
    RID operates based on differences in refractive index between the mobile phase and sample components. This detector is highly sensitive to temperature changes, solvent composition, and the presence of air bubbles, making system stability a crucial factor.
Figure 4. Demonstration of the sample injection process using a syringe in the system of manual injector HPLC.
Figure 5. Internal view of the HPLC system showing the flow path of the mobile phase toward the column and detector.

System Stability Begins with the Mobile Phase

One of the main topics discussed during the training was the importance of ensuring that the mobile phase is free from air bubbles (bubble).

Indications that the System Contains Bubble:

  • Pressure graph fluctuates abnormally
  • Baseline unstable
  • Changes in retention time compared to previous methods

To prevent these issues:

  • The mobile phase must be filtered and sonicated (degassing).
  • The system should first be run with water before switching to the main mobile phase to ensure no air is trapped in the flow path.
  • If bubbleare detected, remove the air until the pressure becomes stable before starting the analysis.
Figure 6. Detailed view of tubing connections and flow paths in the HPLC system that require stable pressure and must be free of air bubbles.

Purging Pump: A Mandatory Step Before Analysis

Purging is performed to remove air from the system. The general purging procedure is as follows:

  • Run the mobile phase with flow rate ±2 mL/min for approximately ±2 minutes.
  • If the pressure is still unstable or bubble are present, the flow rate can be increased up to 4 mL/min (maximum 5 mL/min according to system limits).
  • The process continues until the pressure stabilizes.
  • The duration of purging depends on the system condition.
Figure 7. The HPLC instrument software interface used to monitor system conditions and record chromatogram data during the analysis process.

Maintaining Column Performance and Data Accuracy

Several best practice emphasized during the training:

  • Use a mobile phase that is clear and free from turbidity
  • Avoid excessively high viscosity, as it can increase system pressure.
  • High viscosity over time can accelerate column saturation.
  • Stabilize column temperature to maintain consistency of retention time.
  • Perform gradual flushing when changing solvents with different characteristics.

In the early stages, the system may still show good results. However, without proper procedures, column performance may gradually decline and affect the validity of analytical data.

Figure 8. Explanation of method settings and monitoring of HPLC analysis parameters through the instrument software system.

Building a Culture of Precise Analysis

Training not only focuses on how to operate the instrument but also builds a comprehensive understanding of working principles, potential operational risks, and the importance of standard procedures in maintaining data integrity.
With well-maintained systems and proper procedures, HPLC–RID becomes a strategic instrument in supporting polymer and surfactant analysis for the successful implementation of Chemical EOR.

Monday, February 2, 2026 marked an important milestone for the participants of the Internship Program at the EOR Laboratory ITB who had completed a series of intensive learning activities over the past two months. Final Presentation session held in the Meeting Room of Lab EOR ITB, Energy Building 7th Floor ITB, served as the official closing of the program as well as a reflection on the in-depth study process in the field of Chemical Enhanced Oil Recovery (EOR).

Figure 1. Participants presented a comprehensive evaluation covering laboratory test design, data interpretation, and the development of workflow implementation for Chemical EOR.

This internship program was designed under a hybrid scheme for two months, consisting of one month onsite at the EOR Laboratory ITB and one month offsite (online). This approach provided a balance between hands-on laboratory experience and conceptual deepening, technical discussions, as well as independent literature studies.

Comprehensive Study of Chemical EOR

During the program, participants explored three main components in the implementation of Chemical namely surfactants, polymers, and the ASP (Alkali–Surfactant–Polymer).

In the surfactant study, participants learned about the mechanism of interfacial tension (IFT) reduction between oil and water to enhance the mobilization of trapped oil within reservoir rock pores. This understanding becomes key to improving oil recovery efficiency in the later stages of production.

Figure 2. Participants presented a comprehensive analysis related to polymer mechanisms, adsorption behavior, and Chemical EOR implementation strategies at the field scale.

In the polymer study, the focus was placed on increasing the viscosity of the injection fluid to improve the mobility ratio and enhance sweep efficiency. The analysis of rheological characteristics and polymer stability became an essential part of evaluating the performance of the chemical injection system.

Training Surfactant Screening for EOR: Transforming Research Outcomes into Practical EOR Strategies

Kegiatan Training Surfactant Screening for Enhanced Oil Recovery (EOR) yang membahas penerapan riset laboratorium Chemical EOR menjadi strategi EOR yang aplikatif bagi lapangan migas Indonesia.

Efforts to increase national oil and gas production amid the decline of existing field production require the application of Enhanced Oil Recovery (EOR) technology that is increasingly mature, measurable, and research-based. In response to this challenge, the Training Surfactant Screening for Enhanced Oil Recovery (EOR) was conducted on Tuesday, 9 December 2025, at Best Western Premier The Hive, Cawang, DKI Jakarta.

This training featured Ir. Mahruri, S.T., M.Sc., Project Manager of the EOR Laboratory ITB as well as a Researcher at OGRINDO ITB, as the main speaker. The activity was organized by KOPUM IATMI (Koperasi Jasa Usaha Mandiri Ikatan Ahli Teknik Perminyakan Indonesia) and was attended by professionals from Pertamina RTI.

This training served as a strategic momentum to enhance technical capacity and strengthen the competencies of petroleum professionals, particularly in supporting the development and optimization of EOR technology implementation across various oil and gas working areas in Indonesia.

Figure 1. Ir. Mahruri, S.T., M.Sc. delivering fundamental concepts of Chemical Enhanced Oil Recovery (C-EOR).

Urgency of EOR Implementation in Indonesian Oil and Gas Fields

In the opening session, Ir. Mahruri presented a comprehensive overview of the stages of oil production—ranging from primary recovery, secondary recovery, to Enhanced Oil Recovery. It was conveyed that although waterflood and gas flood methods have been widely implemented, a significant portion of oil remains trapped in the reservoir due to limitations of conventional displacement mechanisms.

In this context, EOR emerges as a strategic solution to:

  • Drain residual oil that is microscopically trapped,
  • Increase recovery factor,
  • Extend the productive life of existing oil and gas fields.

Globally, the contribution of EOR to world oil production continues to increase, particularly in countries with maturefields. Indonesia has significant potential to optimize EOR, especially Chemical EOR, in both sandstone and carbonate reservoirs.

Chemical EOR and the Strategic Role of Surfactants

The main focus of this training was Chemical EOR, with an emphasis on surfactant flooding. Fundamentally, Chemical EOR aims to modify the physicochemical properties of reservoir fluids and rocks through the injection of chemical agents such as alkali, surfactants, and polymers.

Ir. Mahruri explained that surfactants play a crucial role in:

  • Reducing the interfacial tension (IFT) between oil and water to achieve ultra-low IFT conditions,
  • Forming microemulsions capable of mobilizing residual oil,
  • Altering rock wettability (wettability alteration),
  • Improving displacement efficiency and imbibition processes.

The success of surfactant flooding is highly dependent on a comprehensive screening and laboratory evaluation process to ensure that the applied surfactants are truly compatible with reservoir characteristics.

Figure 2. The atmosphere of the Training Surfactant Screening for Enhanced Oil Recovery (EOR) attended by oil and gas professionals from Pertamina RTI in Jakarta.

Surfactant Screening: From Concept to Laboratory Evaluation

One of the main strengths of this training was the in-depth discussion of the laboratory-based surfactant screening workflow, covering fluid–fluid and rock–fluidinteractions, as well as chemical performance in porous media.
Several key tests discussed included:

  1. CMC–IFT Test
    Determines the optimum surfactant concentration to achieve the lowest IFT value. An effective surfactant is expected to reach ultra-low IFT (<10⁻² mN/m) at an economically feasible concentration.
  2. Aqueous Stability Test
    Evaluates surfactant stability and compatibility in injection brine and native brine reservoir to avoid the risk of precipitation and plugging.
  3. Phase Behavior Test
    Assesses microemulsion formation (Winsor Type III) as the main indicator of surfactant effectiveness in mobilizing residual oil.
  4. Thermal Stability & Filtration Test
    Ensures surfactant stability at reservoir temperature and minimizes potential injectivity issues during the injection process.
  5. Wettability, Adsorption, and Imbibition Test
    Evaluates the ability of surfactants to alter rock wettability and minimize surfactant loss due to adsorption.
  6. Coreflooding and Micromodel
    Advanced stages to dynamically simulate surfactant performance in porous media while visualizing displacement mechanisms in two dimensions. displacement secara dua dimensi.

This series of tests emphasizes that Chemical EOR is not merely a chemical injection process, but an integrated scientific approach that must be supported by strong and representative laboratory data.

Bridging Research and Field Implementation

Through this training, participants gained not only conceptual understanding but also practical insights into how research outcomes and laboratory test results can be translated into EOR strategies ready for field implementation.

The discussion also addressed common challenges in Chemical EOR implementation, including:

  • Polymer adsorption and degradation,
  • Surfactant sensitivity to salinity and temperature,
  • Risks of plugging, scaling, and corrosion,
  • Economic considerations and surface facility readiness.

Various case studies and lesson learned from EOR implementations both domestically and internationally enriched participants’ perspectives on the complexity as well as the opportunities of this technology.

Optimization of Enhanced Oil Recovery Using Low Salinity Water and TiO₂ Nanofluid in Sandstone Reservoirs

Microscopic background image of TiO₂ nanoparticles with an overlay title: ‘Investigation of crude oil–brine–rock interaction using low salinity water and TiO₂ nanoparticles,’ highlighting research implications on surface charge and interfacial properties. Includes the OGRINDO ITB logo and a call-to-action button that reads ‘Explore the research findings.

The application of Enhanced Oil Recovery (EOR) technology continues to be a strategic focus in efforts to increase national oil production, especially in reservoirs that have entered the late stage of their productive life. One EOR method that is currently gaining attention is the use of Low Salinity Water (LSW) as an injection fluid. Several studies have shown that low-salinity brine is able to mobilize residual oil more effectively compared to brine with high salinity.

Recent research indicates that the effectiveness of LSW can be further enhanced through the addition of titanium dioxide (TiO₂) nanoparticles. This study becomes important because experimental data regarding the compatibility and synergistic mechanisms of both in the crude oil–brine–rock (COBR) system are still limited.

Why Does Low Salinity Water Become More Effective with TiO₂ Nanoparticle?

Recent laboratory studies investigated crude oil–brine–rock (COBR) interactions within a salinity range of 500–32,000 ppm and TiO₂ concentrations of 0–100 ppm using sample from Berea sandstone. The results show that the addition of TiO₂ into LSW induces significant physicochemical changes, particularly in pH, zeta potential, and contact angle parameters, which directly influence the mechanism of oil detachment from the rock surface.

Figure 2. Mechanistic insight into LSW–TiO₂ interactions affecting interfacial properties and wettability, contributing to enhanced the performance of oil recovery oil recovery.

This combination produces an effective LSW–TiO₂ nanofluid capable of altering the rock wettability toward a more water-wet (wettability alteration). In water-wetconditions, the rock surface is more easily wetted by water, allowing oil that was previously strongly attached to the pore surfaces to move and be produced more efficiently.

Implications for EOR

Findings from this study show that the combination of LSW and TiO₂ nanoparticles has significant potential for optimizing the EOR process in sandstonereservoirs. Modifications of interfacial properties—particularly through changes in wettability—emerge as the main mechanism supporting enhanced oil mobilization.

This study also demonstrates that the tested TiO₂ concentrations provide consistent physicochemical responses, opening opportunities for designing more optimal injection fluids to maximize oil recovery.

In addition to offering a fundamental understanding of fluid–rock interactions under low-salinity conditions, the results of this research provide new direction for developing more effective LSW–TiO₂ nanofluid formulations for field applications. Further studies, such as coreflooding,, are planned as the next step to validate the implications of these findings on direct oil recovery improvement.

CCUS: Indonesia’s Strategic Solution Toward a Low-Carbon Future

Infographic on Carbon Capture, Utilization, and Storage (CCUS) in Indonesia, showing national CO₂ emission trends, geological storage potential in saline aquifers and depleted oil & gas reservoirs, and key CCUS project sites supporting the country’s Net Zero 2060 target.

Indonesia is currently at a crucial stage in its journey toward a low-carbon energy future. As energy demand continues to rise and global pressure to reduce emissions intensifies, Carbon Capture, Utilization, and Storage (CCUS) technology emerges as one of the most strategic solutions to maintain the balance between energy security and environmental sustainability.

Indonesia’s CO₂ Emission Profile

As one of the most populous countries in the world, Indonesia contributes significantly to global carbon emissions. Recent data show that Indonesia’s carbon dioxide (CO₂) emissions have sharply increased from 35.8 million tons (Mt) in 1970 to approximately 729 million tons (Mt) in 2022. This surge is mainly driven by the dominance of fossil fuels—such as coal, oil, and natural gas—in the national energy mix.

Figure 1. CO₂ Emission Trends in Indonesia (1970–2022). Source: Ramadhan et al. (2024) based information from Ritchie & Roser (2023).

Rapid economic and population growth accelerate the increase in energy demand, while the use of renewable energy remains relatively low. This condition underlines the urgency for Indonesia to adopt emission reduction technologies such as CCUS to achieve the Net Zero Emission 2060 target.

The technology of CCUS offers a concrete solution: capturing carbon emissions directly from their sources (such as factories, refineries, or power plants) and safely storing them underground to prevent their return to the atmosphere.

Potential CO₂ Storage Sites in Indonesia

According to Ramadhan et al. (2024) in Energy Geoscience, Indonesia possesses gigaton-scale carbon storage capacity—one of the largest in Southeast Asia. This potential is distributed across several major geological formations:

  1. Depleted Oil & Gas Reservoirs
    Mature oil and gas fields offer great potential for Enhanced Oil/Gas Recovery (EOR/EGR) while serving as CO₂ storage sites. Total capacity: approximately 2,822 MtCO₂ (≈ 2.82 GtCO₂). Main locations: Sumatra and Java.
  2. Saline Aquifers
    Underground saline aquifer formations provide the largest storage capacity. Total capacity: 335,884 MtCO₂ (≈ 335.8 GtCO₂). Main locations: Sumatra, Java, and Kalimantan (Borneo).
  3. Geological Storage Zones
    Areas with porous rock layers, such as sandstone and limestone, also have potential for long-term, safe, and stable carbon storage. Total capacity: 13,863 MtCO₂ (≈ 13.86 GtCO₂). Most located in Sumatra and Java.

With a total potential exceeding 350 GtCO₂, Indonesia holds a tremendous opportunity to become a carbon storage hub in the Asian region.

Figure 2. Carbon (CO₂) Storage Potential in Indonesia by Geological Formation Type. Source: Ramadhan et al. (2024) based information from Zhang & Lau (2022); Bokka & Lau (2023)..
