n: a procedure whereby a product may be subjected to intensified but controlled conditions of heat, pressure, radiation, or other variables to produce, in a short time, the effects of long- time storage or use under normal conditions.

n: a company that is either directly or indirectly controlled and/or owned by another firm or company.

n: a roller cone bit that is specially designed for air or gas drilling. It is very similar to a regular bit, but features screens over the bearings to protect them from clogging with cuttings and thicker hardfacing on the shirttail to protect them from abrasive, high-velocity air or gas drilling fluid.

n: A rig whose every clutch and drawworks brakestaff are controled by compressive air. Usually assisted with hydraulic brake and dynamic brake.

n: (Ac) a white or gray midlevel cloud that appears as closely arranged rolls. This type of cloud is composed of either ice crystals or water droplets.

n: 1. a permeable body of rock capable of yielding groundwater to wells and springs. 2. the part of a water drive reservoir that contains the water.

n: (1) water bearing strata. (2) aqueous section in water controlled reservoir.

a water containing formation that may or may not be directly connected to the hydrocarbon bearing zone. A connected aquifer may or may not offer pressure support to the pay.

n: an adjustable choke that is power-operated to control pressure of flow. See adjustable choke.

n: The adjustable choke controled by pneumatics or hydraulic pressure. Used for controlling the pressure and circulating rate.

n: The equipment controlling the bit weight automatically during drilling.
