Cappucino Permeability and Petroleum System

Pertaining to a condition in which two fluids are incapable of forming molecularly distributed mixtures or attaining homogeneity at that scale. The fluids separate into two phases with an interface between them

• immiscible

• miscible

The ability, or measurement of a rock's ability, to transmit fluids, typically measured in darcies or millidarcies

• Porosity

• Permeability

• Wettability

• Saturation

Pertaining to a condition in which two or more fluids can mix in all proportions and form a single homogeneous phase

• Immiscible

• Miscible

the ability to preferentially flow or transmit a particular fluid through a rock when other immiscible fluids are present in the reservoir (for example, effective permeability of gas in a gas-water reservoir).

• Absolute permeability

• Relative permeability

• Effective permeability

the ratio of effective permeability of a particular fluid at a particular saturation to absolute permeability of that fluid at total saturation.

• Absolute Permeability

• Relative Permeability

• Effective Permeability

the measurement of the permeability conducted when a single fluid, or phase, is present in the rock

• Absolute permeability

• Effective permeability

• Relative permeability

The movement of fluid through pores and fractures within permeable rocks in a reservoir. Generally, the fluid flow is assumed to follow Darcy's law, so the fluid flow may be simulated with a model of the reservoir.

• Fluid Flow

• Liquid Flow

A subsurface body of rock having sufficient porosity and permeability to store and transmit fluids.

• Caprock

• Reservoir

• Aquifer

• Seal

A relatively impermeable rock, commonly shale, anhydrite, or salt, that forms a barrier or seal above and around reservoir rock so that fluids cannot migrate beyond the reservoir

• Caprock or Seal

• Source Rock

Pertaining to a rock that is incapable of transmitting fluids because of low permeability.

• Lost Permeability

• Less Permeability

• Impermeable
