CORE_PREPARATION_METHOD
| Method by which a core sample has been prepared for analysis. |

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. |
