• Hydrostatic pressure

  The force exerted by a body of fluid at rest. it increases directly with the density and the depth of the fluid and is expressed in pounds per square inch or kilopascals. the hydrostatic pressure of fresh water is 0.433 pounds per square inch per foot of depth (9.792 kilopascals per meter). in drilling, the...

• Azimuthal

  In well logging: pertaining to being focused in one direction. an azimuthal, or azimuthally focused, measurement has one or more directions perpendicular to the surface of a logging tool from which it receives most of its signal. examples are the density, laterolog and microresistivity logs. recent applications include azimuthal density and gamma ray in lwd...

  In drilling-fluid terminology, a chemical is any material that produces changes in the viscosity, yield point, gel strength, fluid loss, and surface tension....

• Gas-cut mud

  A drilling mud that contains entrained formation gas, giving the mud a characteristically fluffy texture. then entrained gas in not released before the fluid returns to the well, the weight or density of the fluid column is reduced. because a large amount of gas in mud lowers its density, gas-cut mud must be treated to...

• Weight cut
