Pump pressure, which is also referred to as system pressure loss, is the sum total of all the pressure losses from the oil well surface equipment, the drill pipe, the drill collar, the drill bit, and annular friction losses around the drill collar and drill pipe. It measures the system pressure loss at the start of the circulating system and ...

During circulation, the pressure applied is due to drilling mud weight and also due to the pressure applied by the mud pumps to circulate the drilling fluid. Pressure under circulating condition = Pressure under static condition + Pressure due to pumping at that point or pressure loss in the system. If we convert pressure under circulating ...
On the surface, the received pressure signals are processed by computers to reconstruct the information. The technology is available in three varieties: positive pulse, negative pulse, and continuous wave. [7] Positive pulse Positive-pulse tools briefly close and open the valve to restrict the mud flow within the drill pipe.
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).

Barlow's formula (called "Kesselformel" [1] in German) relates the internal pressure that a pipe [2] can withstand to its dimensions and the strength of its material.. This approximate formula is named after Peter Barlow, an English mathematician.
