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 (TiOā‚‚) 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.”

šŸŒŸ 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 TiOā‚‚ nanoparticles to AEC could drastically alter the systemā€™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 TiOā‚‚ nanoparticles within a concentration range of 0%ā€“0.05% w/w.

The addition of 0.05% w/w TiOā‚‚ nanoparticles to 1.25% w/w AEC surfactant was able to reduce interfacial tension to a value of 5.85 Ɨ 10ā»āµ 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 TiOā‚‚ 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 ā€” especially in fields that have experienced production decline.

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

Surfactant EOR: An Efficient Solution for Optimizing Oil and Gas Production

Diagram showing the fundamental mechanisms of surfactant in Enhanced Oil Recovery, including interfacial tension reduction, wettability alteration, and microemulsion formation

In the oil and gas industry, understanding the fundamental concepts of surfactants is key to developing technologies that are not only efficient but also environmentally friendly and economically viable. Surfactants are far more than ordinary chemical compoundsā€”they play a strategic role in various applications, particularly in Enhanced Oil Recovery (EOR).

Surfactant is surface active agentā€”a chemical compound capable of reducing surface tension between two phases: water and oil. A surfactant molecule consists of two main parts:
ā€¢ A hydrophilic ā€œheadā€ (attracted to the water phase)
ā€¢ A hydrophobic ā€œtailā€ (attracted to the oil phase)

This structure allows surfactants to function as interfacial tension reducers between oil and water, microemulsion formers (emulsifiers), and wetting agents.

Mechanism of Surfactant for Optimal Oil Recovery
Effects of surfactant application on reservoir rocks

Why Choosing the Right Surfactant Matters
There is no one-size-fits-all surfactant for every reservoir. Selection must be tailor-made to match the specific conditions of each reservoir. Factors such as salinity, temperature, rock type, and crude oil characteristics significantly influence surfactant performance in enhancing oil recovery. Therefore, choosing and formulating the right surfactant is critical to optimizing production and reducing operational costs.

OGRINDO and Surfactant Research
As a company rooted in petroleum engineering expertise, OGRINDO (Oil and Gas Recovery for Indonesia) has in-depth competence in the research, development, and application of surfactant technology in the energy sector.
