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.

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.

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.

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.

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.

Four Trapping Mechanisms: How CO₂ Stays Safely Locked Underground

Carbon Capture, Utilization, and Storage (CCUS) in Indonesia explained with trapping mechanisms, global case studies, storage potential, and OGRINDO ITB services to support Net Zero Emission

Climate change caused by the increasing CO₂ emissions is a major challenge we face today. To prevent its impact, Carbon Capture and Storage (CCS) emerges as a proven safe solution to store CO₂ deep underground. CCS not only prevents emissions from reaching the atmosphere, but also becomes an essential foundation of Carbon Capture, Utilization, and Storage (CCUS)—a pathway that allows CO₂ emissions to be transformed into valuable opportunities.

Figure 1. General scheme of a CCS project: starting from capturing CO₂ emissions, transportation, to permanent storage beneath the earth’s surface (Ali et al, 2022)

Four CO₂ Trapping Mechanisms
The long-term security of CO₂ storage is ensured by four natural mechanisms that complement each other over time:

  1. Structural Trapping
    CO₂ that moves upward due to density differences will be stopped by the caprock. Since gas density tends to be smaller than oil and water, CO₂ gas will gradually move in a vertical direction. To ensure CO₂ remains trapped within the formation, caprock yang cukup reliable, with extremely low permeability and wettability that favors strong water wet conditions.
  2. Residual Trapping
    A portion of CO₂ is trapped within the rock pores as small immobile bubbles. This mechanism provides long-term storage stability.
  3. Dissolution Trapping
    CO₂ dissolves into formation water and forms a carbonate solution with a density heavier than the other fluids present in the formation, thus tending to sink downward and reducing the risk of CO₂ leakage.
  4. Mineral Trapping
    Dissolved CO₂ reacts with rock minerals (Ca, Mg, Fe) and forms solid carbonate minerals such as calcite or magnesite. This is the most permanent form of storage because CO₂ transforms into new stable rock over thousands of years.

These mechanisms work in layers: structural and residual provide immediate protection, while dissolution and mineral ensure long-term security. Together, they create a multi-layered line of defense that guarantees CO₂ remains safely stored for centuries.

Figure 2. Layered contribution of CO₂ trapping mechanisms that complement each other over time, ensuring storage security across generations.

CCS as the Foundation of CCUS
Understanding these four mechanisms helps us see that CCS is a crucial first step in the journey toward CCUS. Without secure storage, it is difficult to develop large-scale CO₂ utilization. Through CCS, CO₂ is not only safely stored underground, but also opens opportunities for reuse—for example in Enhanced Oil Recovery (EOR) as part of the CCUS solution.

🌱 This Is Just the First Step
In the next episode, we will discuss how CCUS transforms CO₂ from a burden into a valuable resource, driving industrial innovation and accelerating the transition to cleaner energy.

Micromodel: An Innovative Technology for Optimizing Enhanced Oil Recovery

Micromodel fabrication process for enhanced oil recovery (EOR) research, showing step-by-step visualization from reservoir characterization to micromodel testing in oil-wet conditions.

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

Research breakthrough by OGRINDO ITB on enhancing oil recovery in sandstone using surfactant and titanium dioxide nanoparticles

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.

Figure 1: Contact angles of all tested solutions on the Berea sandstone thin section. Error bars represent the standard deviation of the measurements

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.

One of the most effective and increasingly adopted Enhanced Oil Recovery (EOR) methods is polymer flooding. Polymers function by increasing the viscosity of injected water, enabling it to displace oil more uniformly and improve sweep efficiency. Polymer injection can contribute to an additional oil recovery of 5% to 30% of the Original Oil in Place (OOIP).
