n: the bit which is easy to abrade and with which the drilling rate is low because of ill selected material or harmful fabrication

n: an oil and gas lease on federal land issued under the Mineral Leasing Act. Federal leases usually provide step- scale or sliding-scale royalty;a flat discovery royalty of one-eighth may also be specified.

n: (FOGRMA) congressional act that was designed primarily to assure proper and timely revenue accountability from production and leasing of federal lands.

n: provision in gas purchase contracts that allows the purchaser to reduce the price paid to the producer by an amount that FERC did not allow in the purchasers rate base for ultimate passthrough to the purchasers customer.

n: see exploration well. field facility n: an installation designed for one or more specific field processing unitsscrubbers, absorbers, drip points, compressors, single- or multiple-stage separation units, low-temperature separators, and other types of separation and recovery equipment.

n: a porous medium through which a fluid is passed to separate particles of suspended solids from it.

n: refer tofilteration

n: the main parts of one-step solids controller ,used to depart the solid particles in drilling fluid

n: 1. compacted solid or semisolid material remaining on a filter after pressure filtration of mud with a standard filter press. Thickness of the cake is reported in thirty seconds of an inch or in millimetres. 2. the layer of concentrated solids from the drilling mud or cement slurry that forms on the walls of the borehole opposite premeable formations;also called wall cake or mud cake.

n: (1) The soild residue deposited by a drilling fluid against a porous medium, usually filter paper, according to the standard API filtration test. (2) The soild residue deposited on the wall of a borehole during the drilling of permeable formations.


the layer of solids stranded on the face of permeable formations by liquids driven into the rock by pressure differential towards the formation. When sized correctly the filter cake may completely stop losses.
