Enhanced Oil Recovery (EOR)


Precision analysis yields a better understanding of your reservoir and it's potential through a thorough investigation of EOR alternatives.

Weatherford Laboratories is the world leader in experience for complex gas injection, thermal operations, chemical, and testing. Weatherford Laboratories operates one of the few commercial laboratories in the world with certified sour gas facilities. Our integrated capabilities lead the way in defining and comparing the validity and value of the complete suite of EOR strategies.

Weatherford Laboratories provides understanding of how the reservoir rock and fluids interplay.
We employ six parameters that can be used to screen reservoirs for EOR potential. The understanding of the interplay between these parameters is critical for the successful implementation of any EOR scheme.

Precision analyses and “scalable” results help improve all your EOR requirements from steam flood performance while minimizing the corrosive impacts of H2S to correct chemical selections and optimized gas injection schemes. These results yield a better  understanding of your reservoir and optimized production options. Our in-depth experience also encompasses a variety of plays in a range of reservoir types worldwide, allowing us to apply our science and technology tosupport your program from the pore-scale to field-scale.

Six parameters that control EOR:

  • Phase Behavior

  • Interfacial tension (IFT)

  • Viscosity ratio’s

  • Pore throat size distribution

  • Wettability

  • Gravity

Enhanced Oil Recovery (EOR) Laboratory Tests:

  • Multi-contact experiment - Quantify IFT, viscosity, solubility-associated K values, and Bo and Rs result in accurate modeling of the vaporizing and/or condensing processes that occur in the actual reservoir.

  • Constant IFT core flooding - No mass transfers during the constant IFT core flood result in true residual oil recovery, and none of the core stack is used for establishing a miscible bank permits discriminating between IFT-dominated systems and other reservoir EOR controlling factors

  • Aquathermolysis - High heat + oil + water + sand often results in the generation of H2S and CO2. Aquathermolysis testing can verify the formation of this corrosive gas during the steam flooding process

  • Acid gas testing for applicability to EOR and sequestration - The isolation lab permits the testing of any (lab) volume at any pressure/temperature of acid gas for sequestration or EOR applications in a safe and effective manner

  • Low- and high-temperature multi-phase and heavy oil and bitumen core flooding capability - The only true laboratory model of actual reservoir conditions, steam flooding, solvent assisted stem flooding, and vapex

  • Chemical flooding - Screening and optimization of chemical flood reservoir candidates, including chemically modified water flood

  • Gas injection - Immiscible and miscible gas injection (CO2) are potentially attractive methods of improving oil recovery because they can result in lower residual oil saturations than water flooding alone

  • Low salinity water injection - Low salinity water flooding can alter wetting properties of oil reservoirs and optimize fluid flow and oil recovery in porous medium during production

Increased recovery in a shorter time frameadds to increased revenue and net present value.

Higher standards of interpretation and integration with field processes improve the flexibility of your on-site in situ solutions to optimize hydrocarbon recovery and revenue.
