allowable annular surface pressure.

small pieces of rock broken up by the perforating process.

particles propelled at a velocity sufficient to cause cleaning or wearing away of a surface.

a perforating process involving pumping a slurry of liquid and size particles through a nozzle to cut through steel and rock.

n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

the theoretical maximum flow that a well could deliver with a zero backpressure at the middle of the perforations.

n: a private company in the business of preparing abstracts of title and performing related services. Also called abstract plant.

after closure analysis;a fracture performance test method.

n: a method of joining steel components in which acetylene gas and oxygen are mixed in a torch to attain the high temperatures necessary for welding. As an early type of welding (it was also called oxyacetylene welding),its primary disadvantage was the seepage of molten weld material onto the interior surface of the pipe, often leading to corrosion problems.

n: the process of recording the acoustic characteristics of sub- surface formations, based on the time required for a sound wave to travel a specific distance through rock. The rate of travel depends on the composition of the formation, its porosity, and its fluid content. Also called sonic logging.
