n: (bbl) 1. a measure of volume for petroleum products in die United States. {A)e barrel is the equivalent of 42 US gallons or 0.15899 cubic meters (9,702 cubic inches). One cubic metre equals 6.2897 barrels. 2. the cylindrical part of a sucker rod pimp in whid1 the piston like plunger moves up and down. Operating as a piston inside a cylinder, the plunger and ~I create pressure energy to lift well fluid to the surface.

an oilfield measurement barrel is 42 US gallons or 5.615 ft3 or 6.28 barrels = 1 meters3. Note that reservoir barrels undergo shrinkage by the reservoir volume factor as gas escapes. Stock tank barrels are measured after gas escapes.

n: a laboratory unit used for evaluating or testing drilling fluids. One gram of material, when added to 350 millilitres of fluid, is equivalent to 1 pound of material added to one 42-gallon barrel of fluid.

a laboratory measuring scale for expressing mixtures of products used to formulate muds. One gram of material added to 350 cc of liquid is equivalent to 1 lb of material added to a 42 gallon barrel.

a Standard Oil measure of 42 gallons, originally known as a blue barrel and abbreviated bbl. 0.16 m3.

n: the volume flow rate of the circulating drilling fluid usually expressed in gallons or barrels per minute in the United States. Elsewhere, it is expressed in cubic metres per minute.

n: The circulating rate of drill fluid in the drilling programe.

n: The volume flow rate of the circulating drilling fluid, usually expressed in gallons per minute or barrels per minute.

n: a type of testing used extensively on casing head gas that has a propane content of above 0.5 to ].0 gallon per thousand cubic feet to determine the liquid hydrocarbon content of the gas.

the heat value per unit of fuel expressed in Btu as determined from tests of fuel samples. Examples: Btu per pound of coal, per gallon of oil, per cubic foot of gas (AGA).

n: a unit of volume measurement in the metric system, replacing the previous stagnant unit known as the barrel, which was equivalent to 35 imperial gallons or 42 US gallons. The cubic metre equals approximately 6.2898 barrels.

n: the mass or weight of a substance per unit volume. For instance, the density of a drilling mud may be 10 pounds per gallon, 74.8 pounds/cubic foot, or 1,198.2 kilograms/cubic metre. Specific gravity, relative density, and API gravity are other units of density.

n: Mass per unit volume expressed in pounds per gallon (ppg),grams per cubic (g/cc),or pounds per cubic ft (lb/cu.ft). Drilling-fluid density is commonly referred to as mud weight.


the mass per volume of a substance. Density of fresh water is 8.33 pounds per gallon or 1 gram/cc.

n: a current-measuring instrument that is suspended by a buoy and lowered to a specified ocean depth. The effect of the current on the drogue is shown by the movement of the buoy at the surface. capacities of about 50 to 55 US gallons, or about 200 litres.
