Laboratory Capabilities

The EORI laboratory has been supporting local Wyoming producers since its establishment in 2004. With the newly acquired state-of-the-art lab equipment and the technical expertise in petrology, chemistry, geochemistry, and reservoir engineering, the group has a wide range of laboratory capabilities from rock and fluid analysis to enhanced oil recovery method development for Wyoming reservoirs. Those capabilities include:

EOR Method Evaluation

  • Miscible and near miscible flooding evaluation with CO2 and other solution gases at reservoir conditions
  • CO2 foam flooding evaluation at reservoir conditions
  • Waterflooding and water alternating gas (WAG) flooding evaluation
  • Evaluation of chemical EOR methods including flooding with polymers, surfactants and other ASP fluid.
  • Evaluation of fluid compatibility and effect on rock wettability

Routine Core Analysis

  • Brief core description and detailed petrology studies including thin section, X-ray diffraction (XRD) and scanning electron microscope (SEM) analysis
  • Fluid saturation and core cleaning by solvent extraction methods. Porosity and permeability measurements

Special Core Analysis

  • Coreflooding at reservoir conditions up to 10,000 psi and 300°F
  • Unsteady state water-oil and oil-gas relative permeability analyses
  • Formation damage studies for reservoir cores
  • Reservoir rock wettability studies by Amott Indices
  • Reservoir rock capillary studies with Porous Plate Apparatus

Reservoir Fluids Analysis

  • Reservoir water geochemistry analysis
  • Compositional analysis of gas and oil samples by Agilent Gas Chromatographs
  • Oil molecular weight measurements by Precision Cryoscope
  • Stock tank oil asphaltene contents by ASTM methods
  • Measurements of crude oil acid and base numbers by ASTM titration methods
  • Density and viscosity of stock tank oil with Anton Paar Stabinger Viscometer at specified temperature up to 212°F
  • Reservoir hydrocarbon fluid phase behavior studies with the DBR Phase Behavior Apparatus up to 15,000 psi and 392°F, including bubble point and dew point measurements, swelling tests, and other phase behavior studies
  • Gas-oil ratio and gas-water ratio measurements with DBR Gasometer
  • Single phase reservoir fluid viscosity measurements by Cambridge Viscometer up to 20,000 psi and 375°F
  • Studies of surface and interfacial tensions of reservoir fluids with the CoreLabs Pendant Drop Tensiometer up to 10,000 psi and 350°F and the newly acquired Spring Drop Tensiometer
  • Minimum miscibility pressure (MMP) studies by Slim Tube Apparatus for gas flooding up to 10,000 psi and 350°F
