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).
Oil-based mud [1] is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fuel oil, selected crude oil or mineral oil.
Synthetic-based fluid (SBM) (otherwise known as low-toxicity oil-based mud or LTOBM): Synthetic-based fluid is a mud in which the base fluid is a synthetic oil. This is most often used on offshore rigs because it has the properties of an oil-based mud, but the toxicity of the fluid fumes are much less.
KMW – kill mud weight; KOEBD – gas converted to oil-equivalent at 6 million cubic feet = 1 thousand barrels; KOH – potassium hydroxide; KOP – kick-off point (directional drilling) KOP – kick-off plug; KP – kilometre post; KRP – kill rate pressure; KT – kill truck; KLPD- kiloliters per day
A mud balance, also known as a mud scale is a device used to measure the density (weight) of drilling fluid, [1] cement [2] or any type of liquid or slurry.

Drilling fluid invasion is a process that occurs in a well being drilled with higher wellbore pressure (normally caused by excessive mud weights) than formation pressure. ...
