ParameterDescription
CAPILLARY_PRESSURE_FUNCTION Name of the function used to represent capillary pressure.
CAPILLARY_PRESSURE_FUNCTION_COEFF Coefficients used in the capillary pressure function.
CENTRIFUGE_SPEED The bowl speed of a centrifuge.
CORE_PREPARATION_METHOD Method by which a core sample has been prepared for analysis.
DISPLACING_FLUID_VOLUME Volume of fluid used to to displace another fluid. In special core analysis, may be expressed as unitless multiple of pore volume.
EFFECTIVE_PERMEABILITY_GAS_SOR Effective permeability to gas at residual oil saturation.
EFFECTIVE_PERMEABILITY_GAS_SWI Effective permeability to gas at initial water saturation.
EFFECTIVE_PERMEABILITY_GAS_SWR Effective permeability to gas at residual water saturation.
EFFECTIVE_PERMEABILITY_OIL_SWI Effective permeability to oil at initial water saturation.
EFFECTIVE_PERMEABILITY_WATER_SOR Effective permeability to water at residual oil saturation.
GAS_SATURATION_AT_BREAKTHROUGH Gas saturation at the breakthough point. In Special Core Analysis, breakthough is the appearance of the injected fluid at the outlet face of the rock sample.
GAS_SATURATION_MIN_SO_3PHASE The gas saturation at minimum oil saturation in a three phase system. (SCAL SGM)
INITIAL_GAS_SATURATION Gas Saturation at the beginning of the test, experiment or production.
INITIAL_OIL_SATURATION Oil Saturation at the beginning of the test, experiment or production.
INITIAL_WATER_SATURATION Water Saturation at the beginning of the test, experiment or production.
J_FUNCTION Name of the J Function, a function used to normalize capillary pressure to account for differences in permeability, porosity, and fluid systems.
J_FUNCTION_COEFF Coefficients used in the J function, a function used to normalize capillary pressure to account for differences in permeability, porosity, and fluid systems.
LITHO_DESCRIPTON Textual description of the lithology.
MIN_OIL_SATURATION_3PHASE Minimum oil saturation in a 3 phase system. (SCAL SORM)
OIL_WETTABILITY_INDEX Relative affinity of a mineral surface for oil. Amott
PREPARATION_METHOD Method by which an item or sample has been prepared for subsequent operations or analysis.
RELATIVE_PERMEABILITY_BASIS Absolute or effective permeability basis for the relative permeability.
RELATIVE_PERMEABILITY_FUNCTION Name of the function used to represent relative permeablity.
RELATIVE_PERMEABILITY_FUNCTION_COEFF Coefficients used in the function.
RESIDUAL_WATER_SATURATION The fraction or percentage of water remaining at maximum hydrocarbon saturation, as measured in core analysis. It differs from Irreducible_Water_Saturation because of filtrate invasion and gas expansion from the core being brought to the surface.
SCAL_FLOOD_DIRECTION Direction of fluid flow through the sample in the laboratory (e.g. Horizontal, Downwards, Upwards). Water-oil experiments are almost always horizontal, gas-liquid experiments may be horizontal or vertical. If they are vertical they are done in the gravity stable direction. For example gas flooding an oil filled plug would be downwards, water flooding a gas filled plug would be upwards.
WATER_SATURATION_AT_BREAKTHROUGH Water saturation at the breakthough point. In Special Core Analysis, breakthough is the appearance of the injected fluid at the outlet face of the rock sample.
WATER_SATURATION_AT_BREAKTHROUGH_FF Water saturation at the breakthough point, calculated from fractional flow curve (SCAL SwBkFF). In Special Core Analysis, breakthough is the appearance of the injected fluid at the outlet face of the rock sample.
WATER_SATURATION_MIN_SO_3PHASE The water saturation at minimum oil saturation in a three phase system. (SCAL SWM)
WATER_WETTABILITY_INDEX Relative affinity of a mineral surface for water.
WETTING_CONTACT_ANGLE Angle between a fluid droplet and a solid surface at the point of contact; the lower the angle (measured inside the droplet), the greater the adhesion and thus the greater the wettability of the solid to that fluid.
WETTING_TYPE Classification of the wetting characteristic of the rock, such as Oil Wet or Water Wet.
