American Association of Oilwell Drilling Contractors.

v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

n: A rig drived by DC which is commutated by SCR.

n: (RSPA) a DOT agency that oversees the Office of Pipeline Safety, intermodal containers, highway portable tanks, railroad cars, and anything used in interstate or international commerce not regulated by the coast guard. Under OPA, RSPA has authority over onshore oil and hazardous materials pipelines that are used in interstate commerce. Address: 400 7th Street SW;Washington, DC 20590;(202) 366-4433.

allowance for funds used during construction.

n: oil trade organisation (founded in 1920) that is the leading standardising organisation for oilfield drilling and producing equipment. It maintains departments of transportation, refining, marketing, and production in Washington, DC. It offers publications regarding standards, recommended practices, and bulletins. Address: 1220 L Street NW;Washington, DC 20005;(202) 682-8000.

n: the standard unit of gamma ray measurement. Standardisation of this unit results from the normalisation of the detector-measurement systems of all primary service companies in the API test pits at the University of Houston. The API gamma ray unit is defined as 1/200 of the difference in log deflection between two zones of different gamma ray intensity. The test pit is constructed so that the average midcontinent shale will record about 100 API gamma ray units.

n: a well drilled to confirm and evaluate the presence of hydrocarbons in a reservoir that has been found by a wildcat well.

additional wells drilled after a discovery, to confirm the size of a hydrocarbon deposit. Normally used to run buildup tests, drill stem tests, top and bottom of formation, gather core or fluid samples or other evaluations.

n: The included angle between the table of PDC and the line paralleling bit axis.

n: The small sized handcart used to transport devices and pipes.
