a perforating process involving pumping a slurry of liquid and size particles through a nozzle to cut through steel and rock.

n: 1. in general, a substance added in small amounts to a larger amount of another substance to change some characteristic of the latter. In the oil industry, additives are used in lubricating oil, fuel, drilling mud, and cement. 2. in cementing, a substance added to cement to change its characteristics to satisfy specific conditions in die well. A cement additive may work as an accelerator, retarder, dispersant, or other reactant.

n: The agent put into the drilling fluid in order to change some performances of the drilling fluid or slurry.

a compound incorporated into a gas, liquid, or solid system to alter the properties for a particular purpose.

n: The certain temperature in which mud and slurry lay in order to check out the variable relations between time and performance of mud and slurry.

a patented screen design that allows gravel packing slurry to flow past an annular bridge point that would normally stop the placement of gravel.

n: A method of cementing. Put a stop means below the section of cementing, fill the tailored slurry in the bailer, land to the desired location, open the bailer and make slurry in the well. Repeat the process till all slurry poured into the well.

n: A kind of cementing. Send the slurry into the well through drill pipe or pump of oil tube till the surface of the annular is equal to the surface in the pipe, then elevates drill pipe or oil tube and put the cement plug in the former place.

One of the many forms of the barium sulfate mineral. The BaSO4 material is used in drilling mud as a weighting agent and can produce a slurry of over 20 lb/gal in water.

an estimation of the pumpability of a slurry. Has no direct correlation to viscosity.

n: a colloidal clay, composed primarily of montmorillonite, that swells when wet. Because of its gel-forming properties, bentonite is a major component of waterbase drilling muds. See gel, mud.

a reference to colloidal clay (generally montmorillinite or smectite),generates plastic viscosity due to clay behavior, size and electrostatic layer. A slurry of which used for P&A Purposes will weigh no less than 9 ppg.
