n: a kind of stabilizer on whose wings tungsten-carbide wearproof palm is inlayed

n: the act of putting enough drilling fluid in the wellbore to replace the volume of any pipe or other tools that were removed.

n: (RQ) 1. the quantity of released hazardous materials that, when exceeded, must be reported under CERCLA. The EPA is charged with setting the allowable limits for releases of each hazardous material. If a release exceeds the EPA reportable quantity, CERCLA requires that the owners or operators of the facility notify the National Response Center immediately. 2. SARA (section 304) also requires facilities that release a reportable quantity of an EHS or CERCLA hazardous substance to notify the SERC and the LEPC immediately. This requirement is similar to the CERCLA requirement to notify the NRC in case of reportable releases. Like CERCLA, SARA exempts federally permitted releases, continuous releases, any release contained 00 site, as well as other CERCLA exemptions from RQ reporting requirements. In addition, SARA requires a written followup report to be submitted to the SERC and the LEPC as soon as practicable after the release.

the lowest required reporting level for a material.

n: a small portion extracted from the total volume of material that contains the same proportions of the various flowing constituents as the total volume of liquid being transferred. The precision of extraction must be equal to or better than the method used to analyze the sample.

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: in waterflooding, the entrapment of oil in rocks of lower permeability, where gas space has developed during primary production. The resaturated oil is bypassed by the waterflood as the water seeks the path of highest permeability.
