n: a barometer consisting of a flexible, spring-filled metal cell from which air has been removed and a mechanism that registers. See barograph.

n: The process that superpolymer is destroied by the microbe and macromolecule fractures to micromolecule.

breaking down alkanes by bacterial action. Common by psedomonis and ultramonis bacteria and other bacterial strains that digest parts of the crude oil structures. Useful for remediating oil spills or tank bottom residuals.

n: an aneroid barometer that continuously records atmospheric pressure values on a graph or chart.

n: an instrument for measuring atmospheric pressure. See aneroid barometer, mercury barometer.

n: a refinery roilt from the ground up. as opposed to one to which an addition or a modification has been made.

n: refer tobaroid reometer

n: a guard-electrode log that measures the resistivity of the flushed zone.

n: schlumberger wireline tool that used for microinduction sensor to measure the variations of formation conductivity. Applications include determination of stuctural dip when non-conductive mud is in use and borehole geometry.

n: 1. a scraping tool that is forced through a pipeline or flow line to clean out accumulations of wax, scale, and debris from the walls of the pipe. It travels with the flow of product in the line. cleaning the pipe walls by means of blades or brushes affixed to it. Also called a line scraper or a go-devil. 2. a batching cylinder with neoprene or plastic cups on either end and used to separate different products travelling in the same pipeline. 3. a neoprene displacement spheroid, automatically launched and received. used to displace liquid hydrocarbons from natural gas pipelines. 4. in hydro- static testing of a pipeline. a scraper used inside the line to push air out ahead of the test water and to push water out after the test. v: to force a device called a pig through a pipeline or a flow line for the purpose of cleaning the interior walls of the pipe. separating different products. or displacing fluids.

a flow line clearing device, pumped through the line with normal flow.
