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).
P = 0.052 * mud weight * true vertical depth. taught in almost all petroleum engineering courses worldwide, the mud weight (MW) is expressed in pounds per U.S. gallon, and the true vertical depth (TVD) is expressed in feet, and 0.052 is a commonly used conversion constant that can be derived by dimensional analysis:
Oil companies typically measure density in pounds per gallon (ppg) or kilograms per cubic meter (kg/m 3) and pressure measurement in pounds per square inch (psi) or bar or pascal (Pa). Pressure increases with fluid density. To find out the amount of pressure fluid of a known density exerts per unit length, the pressure gradient is used. The ...
