n: the amount by which drilling fluid density is reduced by entrained formation fluids or air.

n: an instrument near the drillers position on a drilling rig that shows both the weight of the drill stem that is hanging from the hook (hook load) and the weight that is placed on the bit by the drill collars (weight on bit).

a string weight measurement device that can report the weight on the string at any time.

n: (WOB) the amount of downward force placed on the bit by the weight of the drill collars.

n: The weight on the drill bit when drilling.

n: A kind of sensor that can measure the loading of casing hook .

a weight bar in a wireline tool BHA.

v: to increase the weight or density of drilling fluid by adding weighting material.

n: Adding weighted material in the drilling fluid, which can increase the density of slurry.

increase fluid density.

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.
