n: a clause in a contract currently governed by regulatory price ceilings to provide a process to reset the price of gas should price controls and regulatory authority cease.

n: the crew member who handles the upper end of the drill string as it is being hoisted out of or lowered into the hole. On a drilling rig, he or she is also responsible for the circulating machinery and the conditioning of the drilling or workover fluid.

n: a contact closure change, or other signal, that starts or stops a prover counter/timer and defines the calibrated volume of the prover.

n: in a pipe prover, an electrical switch activated by the displacement sphere as it moves through the U-portion of the prover. Activating the switch sends an electric current through a cable to a pulse generator.

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.

n: drilling d1at occurs after the initial discovery of hydrocarbons in a reservoir. Usually, several wells are required to adequately develop a reservoir.

n: 1. a well drilled in proven territory in a field to complete a pattern of production. 2. an exploitation well.

n: A well drilled in a proven field to exploit known reserves. Usually one of several wells drilled from a central platform.

wells that are drilled after the discovery and appraisal wells to develop the hydrocarbon production potential of the field.

n: a drill bit that has small industrial diamonds embedded in its cutting surface. Cutting is performed by the rotation of the very hard diamonds over the rock surface.

n: A tool for drilling rock that works by scraping industrial grade diamonds against the bottom of the hole. The diamonds are embedded into the metal structure (usually a sintered or powdered carbide base matrix) during the manufacture of the bit. The bit de

n: Recovering the diamond of bit until the diamond bit cannt drill effectively.

n: a dome or anticlinal fold in which a mobile plastic core has ruptured the more brittle overlying rock. Also called piercement dome.

a salt or other column that pierces upper layers and may form traps of obstructions to flow.
