a failure mode that can cause the cancellation-of or immediate-halt-to a project or event. Generally expressed as a percent probability.

n: 1.the injection of air into a reservoir in a pressure maintenance or an in situ combustion project. 2. the injection of fuel into the combustion chamber of a diesel engine by means of a jet of compressed air.

a comparable reservoir with many similar characteristics (e.g., lithology, depositional environment, porosity, perm, drive mechanism, produced fluids, etc.) that can be used for behavior projections comparison studies.

n: the pattern of minute projections from a metal surface produced by sandblasting, shot blasting, or chemical etching to enhance the adhesiveness of surface coatings.

n: A factor reflecting wellbore deflection. It is defined as the included angle between the north and the projection of tan of survey point in the level.

an oil and gas partnership that has not committed to a specified project at the time of amassing capital.

n: the steel projections on a crane struck by the boom if it is raised too high or lowered too far.

the amount of heat input required to raise the temperature of one pound of water by 1oF at water’s maximum density at 39oF. It is approximately equal to 1 kilojoule.

n: trade name for appratus for cleaning and freeing oil tanks of gas by means of high-pressure jets of hot water. It consistes essentially of opposed double nozzles, which rotate slowly about their horizontal and vertical axes and project two streams of hot water at a pressure of 175 psi (1,206 kilo pascals) against all inside surfaces of the deck, bulkheads, and shell plating.

n: beams that project outward from a structure and are supported only at one end.
