n pi: petroleum fractions, such as ethylene, that are relatively light in molecular weight.

n: all solids that not belong to inertial heavy weight additive in drilling fluid, its density less than the additive.

n: the additive that lower the density of cement.

n: making of cement and small scale of light material.

a cement with a slurry density less than the normal approximate density of 16 lb/gal (1.92 g/cc) density. Normally in the range of 11 to 14 lb/gal (1.32 to 1.68 g/cc).

n: a hole cut into a strengthening member that reduces its weight but does not significantly affect its strength.

n: drilling a hole in a large intensity part to lower the weight, it should not affect the intensity.

n: Fe2o3 * nH2O, usually it refers to the secondary ore that iron bearing mineral is oxidated, the relative density is 3.6 to 4.0, it can be seen as heavy weight additive.

n: a slip device that attaches the liner to the casing. See liner.

n: a slip type device that supends the liner inside the previous casing shoe.

a packer-like hanger with slips suitable for hanging liner weights. May or may not incorporate a seal.

n: the crude oil or product that is forced into the hatch or up around the edges of a floating roof by the weight of the roof.

n: 1. in mechanics, the weight or pressure placed on an object. The load on a bit refers to the amount of weight of the drill collars allowed to rest on the bit. See weight on bit. 2. in reference to engines. the amount of work that an engine is doing;for example, 50 percent load means that the engine is putting out 50 percent of the power that it is able to produce. 3. the amount of gas delivered or required at any specified point or points on a system;load originates primarily at the gas-consuming equipment of the customer. v:1. to engage an engine so that it works. Compare idle. 2. to set a governor to maintain a given pressure as the rate of gas flow through the governor varies. Compare demand.

n: the amount of weight a device can safely carry or support.
