n: a packer whose packing elements are activated when weight from the tubing string is applied. To set some packers, rotation as well as weight is required. See packer.

n: (WACOG) cost calculated as the total cost of all gas purchased during a base period divided by either the total quantity purchased (unit of production) or the system throughput (unit of sales) during the same period. This rate, plus any application of any pending surcharge adjustments, serves as the basis on which system tariff rates are computed and made effective.

n: It can increase density of cement slurry ,ususlly add the inert weighted fraction in the cement.

n: a material that has a high specific gravity and is used to increase the density of drilling fluids or cement slurries.

n: A high-specific gravity and finely divided solid material used to increase density of a drilling mud. (Dissolved salts that increase fluid density, such as calcium bromide in brines, are not called weighting materials.) Barite is the most common, with min

solids added to increase density in a fluid.

n: a metal plate installed in a separator, treater, or mud tank and used to regulate liquid level or, in the case of a metering separator, to measure flow.

n: The drill collar that be welded with alloy steel sub at two end of carbon machinary collar.

n: The drill pipe that be welded with drill pipe sub.

n: The kelly that its body and the sub be connectted by welding.

n: The tool joint be welded on the body of drilling pipe.
