n: the ability of an item to operate as specified for an indicated time period. Often expressed as mean time between failures (MTBF) or mean time to failure (MTfF).

the ability to perform a design function at a specified set of conditions over a target time period.

n: 1. the closeness of the results of successive measurement of the same quantity carried out by the same method, by the same person with the same measuring instrument at the same location over a short period of time. 2. the ability of a meter and prover system to repeat its registered volume during a series of consecutive proving runs under constant operating conditions.

v: to increase or maintain reservoir pressure by injecting a pressurized fluid (such as air, gas, or water) to effect greater ultimate recovery.

n: To recover the pressure of oil layer,inject water or gas into the oil layer with decaying product from one or more well to increase reservoir pressure so as to improve the product and recovery ratio

n: 1. the closeness of the results of measurements of the same quantity where the individual measurements are made by different observers using different methods with different measuring instruments at different locations after a long period of time, or where only some of the factors listed are different. 2. the ability of a meter and prover system to reproduce results over a long period of time in service where the range of variation of pressure, temperature, flow rate, and physical properties of the metered liquid is negligibly small.

n pl: the unproduced but recoverable oil or gas in a formation that has been proved by production.

a calculation of the amount of hydrocarbon reserves that are in the formation. Proven reserves have a very high degree of recovery with wells in place and techniques that are proven.

Behind-pipe reserves are expected to be recovered from zones in existing wells, which will require additional completion work or future re-completion prior to the start of production (SPE).Proximity Log: pad contact tool that measures resistivity.

Developed reserves are expected to be recovered from existing wells, including reserves behind pipe. Improved recovery reserves are considered developed only after the necessary equipment has been installed, or when the costs to do so are relatively minor

Reserves consistent with the cost recovery plus profit hydrocarbons that are recoverable under the terms of the contract or lease are typically reported by the upstream contractor (SPE).

Reserves subcategorized as non-producing include shut-in and behind-pipe reserves. Shut-in reserves are expected to be recovered from (1) completion intervals which are open at the time of the estimate, but which have not started producing, (2) wells whic
