n: 1. a section of pipe or fitting used to join pipe to pipe or to a vessel. 2. a place in electrical circuits where wires join.3.the action of adding a joint of pipe to the drill stem as drilling progresses.

n: the joining of a section of drilling pipe to another

n: preservation;economy;avoidance of waste. It is especially important in the petroleum industry, since the amount of oil and gas is finite. Many conservation practices, such as the trapping of condensable vapours, are used in the industry.

n: a promise or an act of legal value bargained for and received in return for a promise;an essential element of a contract. In oil and gas leases, consideration may be payment in money or in kind;it must often be .serious. consideration. Compare bonus consideration.

n: the cohesion of the individual particles of a given materal (i.e., its ability to deform or its resistance to flow).

n: The viscosity of a non-reversible fluid, in poises, for a certain time interval at a given pressure and temperature.

a fluid’s ability to deform and flow and its general cohesion to itself.

a group of unrelated companies working on a specific venture.

n: One of optimization method of drilling. Find the optimal drilling arrangement by changing bit load and keep rotate speed.

n: 1. a vessel or piece of equipment in which two or more substances are brought together. 2. a switch used to open or close an electric circuit.

the heat value per unit of fuel expressed in Btu as determined from tests of fuel samples. Examples: Btu per pound of coal, per gallon of oil, per cubic foot of gas (AGA).

n: a zone of steep, variable topography forming a transition from the continental shelf edge to the ocean basin.

n: a log used to determine the contribution of each zone to the total production or injection. These sureys are used to indicate chages in the flow pattern versus changes in conditions at the suface, in time, in type of operation, or after stimulation treatments;particularly useful for measuring gas well flow.
