n: wearing away by friction.

wearing away by friction.

n: a device that measures mechanical force. The energy measured is absorbed by frictional or electrical resistance.

annular friction pressure.

n: The pressure that drilling fluid overcomes friction when it flow in the annular space.

n: The pressure deficiency through the flowing direction due to friction resistance when drilling fluid flows in the annular.

n: metal alloy, either tin-based or lead-based, used primarily in friction bearings.

a soft metal alloy used in some seals and bearings.

n: The pressure within a system caused by fluid friction or an induced resistance to flow through the system. Hydraulic Thru-Tubing Fishing tools are typically operated using back pressure created by fiow through a nozzle.

a pressure caused by a restriction or fluid head that exerts an opposing pressure to flow.

Static condition of the length of tubing in the well, where buoyed tube weight (well fluid sensitive) equals the well pressure acting against the cross-sectional area of the tube. The balance point does not include any frictional forces exerted by frictio
