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

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.

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.

Opening Opportunities for Strategic Collaboration

Through this activity, OGRINDO ITB and the EOR Laboratory ITB reaffirmed their commitment to supporting the development of EOR technology based on research, laboratory testing, and close collaboration with industry.

Opportunities for collaboration are open for:

  • Research and development of Chemical EOR,
  • Surfactant screening and laboratory evaluation,
  • EOR feasibility studies,
  • Technical training and consultancy,
  • Industry–academia collaborative projects.

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

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.

Figure 1. Illustration of crude oil–brine–rock (COBR) interaction in the LSW–TiO₂ study.

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.

Figure 2. Changes in zeta potential (ZP) values at various TiO₂ concentrations and salinity levels.

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.

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.

CCUS in Action: Global Success Stories and Lessons for Indonesia’s Low-Carbon Future

In facing the challenge of climate change, Carbon Capture, Utilization, and Storage (CCUS) technology has become one of the proven, real-world solutions globally. From offshore CO₂ storage to natural mineralization into rock, flagship projects in Norway and Iceland have demonstrated that carbon emissions can not only be controlled but also utilized to create new economic value. With a scientifically verified track record of implementation, CCUS has now become a vital pillar in the transition toward a cleaner and more sustainable energy future.

Toward a Low-Carbon Future Through the Implementation of Scientifically Verified CCUS Technology

Amid the urgency of the global energy transition, Carbon Capture, Utilization, and Storage (CCUS) technology has become one of the main pillars in efforts to reduce carbon emissions. Through implementation in various countries, CCUS has proven effective not only in reducing greenhouse gas emissions but also in enhancing economic efficiency and energy industry sustainability.
The following two global success stories show that low-carbon solutions are not merely concepts — they are already a reality.

Sleipner (Norway): A Pioneer in Offshore CO₂ Storage

Launched in 1996 by Equinor (formerly Statoil), the Sleipner Project is located in Sleipner West gas field, approximately 250 km southwest of Stavanger, Norway, in the Central North Sea. This project is the world’s first commercial CCS project, injecting CO₂ separated from natural gas into the Utsira Formation situated about 800–1000 meters below sea level. To date, more than 16 million tons of CO₂ have been safely stored in the Utsira Formation. The success of Sleipner is supported by rigorous 3D seismic and gravimetric monitoring systems, ensuring no CO₂ leakage from the storage layer. With efficient storage costs, the project proves that CCS can operate safely and economically while complying with Europe’s strict environmental regulations.

CarbFix (Iceland): Turning CO₂ into Stone

Beneath Iceland’s basaltic subsurface, the CarbFix Project transforms the concept of CCS into something more permanent — natural mineralization. By dissolving CO₂ into water and injecting it into reactive basalt rocks, more than 95% of the CO₂ is converted into carbonate minerals.
The advantage of this method lies in long-term storage security: carbon is converted into solid minerals, eliminating the risk of leakage. To date, CarbFix has stored more than 100,000 tons of CO₂ beneath Iceland. The rapid mineralization method developed by the project is now being adapted in various countries — including Norway, the United States, and India — through research initiatives applying similar principles to permanently store carbon in basaltic rocks.

What Indonesia Can Learn

Indonesia has a carbon storage potential of approximately 400 gigatons of CO₂ across various geological formations — including oil and gas reservoirs, deep sandstones, and saline aquifer distributed in Sumatra, Kalimantan, and Java. This potential places Indonesia among the countries with the largest carbon storage capacity in Southeast Asia.
However, experiences from Sleipner (Norway) and CarbFix (Iceland) show that the sustainability of Carbon Capture, Utilization, and Storage (CCUS) implementation depends not only on technology but also on a robust supporting ecosystem: regulation, collaboration, and public trust.

Map of CCS/CCUS projects currently under development in Indonesia. The illustration highlights potential carbon storage locations in key strategic regions. Source: Wibisono, N. (2024), “CCS in Indonesia,” Energy Geoscience.

1️⃣ Strong and Adaptive Regulatory Framework
An important step has begun with Presidential Regulation No. 14 of 2024 concerning the Implementation of Carbon Capture and Storage (CCS) Activities, which serves as Indonesia’s first national legal framework comprehensively regulating CCS implementation. This regulation defines key terms, licensing mechanisms, and business and technical schemes for CCS. It provides clarity on CO₂ storage rights, responsibilities, and post-closure monitoring mechanisms.

In addition, the Ministry of Energy and Mineral Resources (ESDM) has issued a Technical Guideline for CCS/CCUS Implementation, serving as a reference for industries and research institutions in conducting feasibility studies, injection design, and field monitoring.

2️⃣ Cross-Sector Collaboration
In line with global practices, the successful implementation of CCS/CCUS in Indonesia requires synergy among the government, the energy industry, academia, and research institutions. This is where the role of the Bandung Institute of Technology (ITB) and OGRINDO ITB becomes crucial — bridging laboratory research, reservoir modeling, and field testing with industry needs.
Collaboration with national oil and gas companies such as Pertamina Subholding Upstream and international partners also opens vast opportunities for CCS/CCUS pilot project , particularly in mature oil fields.

3️⃣ Scientific Monitoring and Data Transparency
From the experiences of Sleipner and CarbFix, it has been proven that science-based monitoring and data transparency are key factors in maintaining public trust and long-term project sustainability. Sleipner, for instance, has conducted 4D seismic monitoring and gravimetric surveys for over 20 years to ensure CO₂ storage safety, while CarbFix makes its research data publicly available to promote innovation and global collaboration.

A similar approach can be applied in Indonesia — by establishing open monitoring and reporting systems accessible to government, academia, and the public, thereby strengthening trust in CCUS implementation.

Through this integrated approach, Indonesia has a great opportunity to replicate global success and realize its first commercial CCS/CCUS project by 2026, as outlined in the National Energy Transition Roadmap. Currently, several national energy companies have initiated CCS/CCUS feasibility studies at multiple oil and gas fields, including the Gundih Field (Central Java) and the Tangguh Field (West Papua), both targeted as pilot projects before 2026. These early implementations will lay the foundation for a long-term carbon storage ecosystem in Indonesia. The success of these pilot projects will mark a crucial milestone in achieving the Net Zero Emission 2060 target. Net Zero Emission 2060.

🌱 From Research to Action

CCUS technology is not merely a future solution — it is a strategic investment to ensure national energy sustainability and industrial competitiveness in the green transition era. Through collaborative research, technological innovation, and knowledge transfer, OGRINDO ITB is committed to supporting the development of CCS/CCUS from laboratory stages to field-scale implementation.

With clear policies, multi-sector collaboration, and strong scientific foundations, Indonesia is ready to move from research to real-world implementation — turning carbon from a burden into an opportunity to build a clean, globally competitive energy future.

Micromodel: An Innovative Technology for Optimizing Enhanced Oil Recovery

Amid the challenges of enhanced oil recovery (Enhanced Oil Recovery), laboratory methods capable of visually representing fluid displacement mechanisms have become increasingly crucial. This is where the micromodel emerges as an innovative solution proudly developed by Indonesian researchers.

Micromodel is a two-dimensional laboratory device designed to replicate the pore structure of reservoir rocks, such as sandstone or carbonate rocks. Through a micromodel, the movement of fluids—such as water, oil, surfactants, and polymers—can be observed directly and in real-time.

Comparison of coreflood and micromodel flooding methods in observing fluid flow in reservoir rocks

Most conventional laboratory tests, like coreflooding, have limitations in providing direct visualization of chemical injection mechanisms. Micromodel address this challenge by enabling real-time observation of interfacial tension changes, wettability alteration, and viscosity displacement efficiency at the pore scale.

What Is the Purpose of Using a Micromodel?

Micromodel are used to:

  • Visually analyze the working mechanisms of chemical EOR
  • Evaluate the effectiveness of surfactants or polymers before upscaling to larger tests
  • Design efficient and targeted injection strategies
  • Identify phenomena such as channeling, viscous fingering, and oil entrapment often undetectable in conventional tests

Micromodel of OGRINDO ITB have some advantages:

  • Indigenous Innovation: Designed and developed by skilled local researchers.
  • Fast, Simple, and Cost-Effective: More efficient than coreflooding, in terms of time and cost.
  • Costumized Design: Tailored to match pore characteristics of sandstone or carbonat, even based on actual reservoir data.
  • Real-Time Visualization: Enables direct observation of fluid behavior at the microscopic scale.
  • Supports More Accurate EOR Design: Acts as a bridge between laboratory results and real-field applications.

Fabrication Process of the Micromodel

Fabrication process of micromodel includes the following stages:

Five main stages of micromodel
  1. Reservoir Characterization: Identifying the physical and petrophysical properties of the reservoir rock, such as porosity, permeability, fluid saturation, and geological structure.
  2. Thin Section & Petrography Analysis: Observing ultra-thin rock slices under a microscope to study mineral composition and rock textures.
  3. Rock Digitization: Converting physical rock data into 2D or 3D digital models.
  4. Micromodel Fabrication: Creating the micromodel through pore-pattern design, etching, and assembling materials using techniques such as thermal bonding.
  5. Micromodel Ready to Use: Final stage where micromodel has passed all fabrication and characterization tests, making it ready for EOR experiments such as surfactant or polymer injection or other EOR mechanism.

The key advantage of OGRINDO's micromodel lies in its design flexibility. By incorporating actual geological and petrophysical field data, micromodel can be customized to closely replicate real reservoir conditions. This makes the experimental results more relevant and reliable for supporting technical decisions in the field.

Visualization of oil-wet state in the micromodel

🔬 Micromodel is more than just a testing device—it is a window into a deeper understanding of subsurface fluid behavior. With OGRINDO ITB, let’s create smarter, more efficient, and data-driven EOR solutions.

OGRINDO ITB Research Breakthrough: Combination of Surfactant & Titanium Dioxide Nanoparticles, Enhances Oil Recovery in Sandstone Reservoir

Innovation in technology Enhanced Oil Recovery (EOR) continues to evolve to address production challenges in mature oil fields. One of the current approaches gaining attention from researchers is the utilization of titanium dioxide (TiO₂) nanoparticles to improve surfactant performance in oil recovery processes, particularly in sandstone.

A research team from OGRINDO ITB recently published their latest research findings in a scientific article titled:
“Enhancement of Surfactant Performance via Titanium Dioxide Nanoparticles: Implication for Oil Recovery in Sandstone.”

🌟 What Makes This Research Special?

Surfactant alkyl ethoxy carboxylate (AEC) surfactant is one of the chemical agents commonly used in EOR methods. However, the OGRINDO team went further by exploring how the addition of TiO₂ nanoparticles to AEC could drastically alter the system’s performance. Comprehensive testing was conducted, covering:

  • Interfacial tension
  • Contact angle
  • Zeta potential
  • Coreflooding test

State of the Art

The latest innovation in this research is the evaluation of AEC surfactant performance by adding TiO₂ nanoparticles within a concentration range of 0%–0.05% w/w.

The addition of 0.05% w/w TiO₂ nanoparticles to 1.25% w/w AEC surfactant was able to reduce interfacial tension to a value of 5.85 × 10⁻⁵ mN/m. This excellent performance was also confirmed in the coreflooding,, where oil recovery increased to a maximum value of 59.52%.

This finding highlights the importance of TiO₂ nanoparticle stability in surfactant solutions, which turns out to be the key factor in enhancing oil recovery efficiency.

Why Is This Important?

This research provides valuable new insights into the development of surfactant- and nanoparticle-based EOR methods. With this approach, it is expected to open new opportunities for improving oil recovery efficiency from sandstone reservoir — especially in fields that have experienced production decline.

This discovery also strengthens OGRINDO’s position as a leading EOR research center in Indonesia, focusing on the development of environmentally friendly, sustainable technologies tailored to national industry needs.
