oil in place in the reservoir; retained in a reservoir as residual gas saturation is an inverse function of the pressure, due to the physics of gas.
Industry:Oil & gas
1. the elevated work area adjacent to the vdoor and ramp on a drilling rig where pipe is laid to be lifted to the derrick floor by the catline or by an air hoist. See catline. 2. any elevated walkway.
Industry:Oil & gas
an electric well log in which the conductivity of the formation rather than the resistivity is measured. Because oil-bearing formations are less conductive of electricity than water-bearing formations, an induction survey, when compared with resistivity readings, can aid in determination of oil and water zones.
Industry:Oil & gas
the average pressure within the reservoir at any given time. Determination of this value is best made by bottomhole pressure measurements with adequate shut-in time. If a shut-in period long enough for the reservoir pressure to stabilize is impractical, then various techniques of analysis by pressure buildup or drawdown tests are available to determine static reservoir pressure.
Industry:Oil & gas
a pit in the ground to provide additional height between the rig floor and the well head to accommodate the installation of blowout preventers, ratholes, mouseholes, and so forth. It also may collect drainage water and other fluids for subsequent disposal.
Industry:Oil & gas
a packer with an element that inflates by means of gas or liquid pumped from the surface through a line. It is deflated by means of slots that can be opened to allow the gas or liquid to flow out. They are used when a temporary packer is needed in a hole.
Industry:Oil & gas
a permeable rock that may contain oil or gas in appreciable quantity and through which petroleum may migrate.
Industry:Oil & gas
a powder consisting of alumina, silica, lime, and other substances that hardens when mixed with water. Extensively used in the oil industry to bond casing to the walls of the wellbore.
Industry:Oil & gas
1. a high-pressure gas injected into a formation to maintain or restore reservoir pressure. 2. gas injected in gas-lift operations.
Industry:Oil & gas
the electrical resistance offered to the passage of current; the opposite of conductivity.
