Advanced Coreflood Studies & Enhanced Oil Recovery (EOR)

Advanced coreflood studies and enhanced oil recovery solutions.

Analytical and consulting solutions for enhanced oil recovery (EOR), enabling you to optimize the extraction of your oil beyond that recoverable by primary and secondary methods.

Responding to an ever-increasing demand, petroleum engineers are continually being challenged to develop new and improved techniques and strategies for hydrocarbon recovery. With expert knowledge in sophisticated, multi-disciplinary EOR studies, and our integrated laboratory and consultation services, we offer a comprehensive understanding of your reservoir.

Why choose EOR solutions from SGS?

We help you to:

  • Benefit from the highest level of experience, reliable analytical results and engineering consulting services for all your EOR projects
  • Gain expert advice on the best methodology, adapting it to the specific conditions of your reservoir
  • Reduce the risks and uncertainties when undertaking pilot and full field EOR project designs
  • Access a range of EOR studies, including advanced flood, interfacial tension, advanced fluid studies and recovery tests

Our range of EOR studies include:

  • Chemical EOR (cEOR) and optimization
  • Miscible and immiscible gas injection, including water alternating gas (WAG)
  • Multi-phase solubility or swelling studies
  • Slim tube miscibility and immiscible displacement studies
  • Forward and reverse multi-contact studies
  • Gas revaporization studies
  • Custom studies (e.g., asphaltene + EOR)

Our advanced flood studies include:

  • Physical simulation through actual measurement:
    • Waterflooding and low salinity
    • Gas injection, WAG cyclic gas
    • Chemical injection – polymer, surfactant, alkaline and alkali/surfactant/polymer (ASP)
    • Hybrid methods (solvent and gas, chemical and gas, etc.)
  • Flow assessment at reservoir conditions
  • Optimization and injectivity improvement
  • In-situ rheology at specified conditions
  • Evaluation of chemicals performance
  • Dynamic adsorption and recovery parameters
  • Microemulsion characterization
  • Relative permeability
  • Formation damage
    • Rock-fluid compatibilities studies
    • Asphaltene deposition
    • Permeability impairment
    • Post-test analysis of produced fluids
  • Carbon sequestration and storage

Our interfacial tension studies include:

  • Optimization of chemical formulations
  • Gas (CO2) miscibility studies
  • Wettability changes due a gas, solvents or chemical injection
  • Phase behavior studies
  • IFT and contact angles at high temperature and high pressure

Our advanced fluid studies include:

  • Solubility-swelling
  • Multi-contacts
  • Miscibility studies w/ Slim Tube
    • Miscibility mechanism identification
    • Minimum miscibility pressure (MMP)
    • Minimum miscibility enrichment (MME)

Why SGS?

We offer a full range of multidisciplinary testing facilities to cater for the unique aspect of every reservoir and EOR project. We maximize the economics of your reservoir by using state-of-the-art laboratory equipment and methodologies to rapidly and efficiently characterize all phases of your EOR project.

Our proven track record of EOR projects includes:

  • Miscible floods on Alaska’s North Slope
  • Gas injection/miscible displacement in Venezuelan heavy oil fields with concurrent asphaltene deposition measurements
  • CO2 sequestration in Argentina
  • WAG studies in Colombia
  • Solubility/swelling with concurrent asphaltene deposition in Algeria
