the water initially in vapor phase within a gas that condenses out when gas cools. Usually 1 to 2 bbls per million scf.

n: the percentage of total pore space in a reservoir occupied by water. It is normally estimated by electric log calculations, although cores specially obtained may be analyzed for this value.

n: a relatively small volume of water that is put into the drill string or tubing string on top of the drilling or workover fluid.

n: I. using the location of the oil-water interface to determine the volume of free water in a shore tank or vessel compartment. 2. the line of demarcation of the oil-water interface.

n: the state of the atmosphere at a specific time with respect to heat or cold, wetness or dryness, calm or storm, and clearness or cloudiness. The term is also used to identify rain, storm, or other unfavorable atmospheric conditions. v: to allow an object or substance to age, usually under controlled conditions.

v: of a storage tanker or shuttle vessel that is permanently moored, to make a 3600 circle around the mooring as the weather changes.

n: a formula for a trigonometric calculation to determine the oil remaining on board (ROB) when the vessel is out of trim and the ROB does not contact both forward and aft bulkheads. The formula assumes ROB to be a flowable liquid.

n: a mathematical means of approximating the small quantities of liquid and solid cargo and free water on board before a vessel is loaded and after its cargo is discharged, based on cargo compartment dimensions and vessel trim. It is used only when a wedge exists and when the liquid does not touch all bulkheads.

n: the methods used to control a kick and prevent a well from blowing out. Such techniques include, but are not limited to, keeping the borehole completely filled with drilling mud of the proper weight or density during all operations, exercising reasonable care when tripping pipe out of the hole to prevent swabbing, and keeping careful track of the amount of mud put into the hole to replace the volume of pipe removed from the hole during a trip.

using barriers to prevent unwanted flow of hydrocarbons to surface.
