particles propelled at a velocity sufficient to cause cleaning or wearing away of a surface.

n: the property by which a fluid in motion offers resistance to shear and flow. Usually expressed as newton seconds/metre.

the measure of a fluid’s ability to resist flow without regards to its density. It is defined as a fluid’s kinematic viscosity multiplied by its density.

n: the maximum volume of natural gas that can be processed through an absorber at a specified absorption oil rate, temperature, and pressure without exceeding pressure drop or any oilier operating limitation.

n: a system consisting of a beacon positioned on the seafloor to transmit an acoustic signal, a set of three or four hydrophones mounted on the hull of a floating offshore drilling vessel to receive the signal, and a position display unit to track the relative positions of the rig and the drill site. Monitoring of the display unit aids in accurate positioning of the rig over the site.

prep: over. The term usually relates conditions of fluid flow 00 me side of a piece of equipment to conditions on the opposite side (e.g., a pressure drop across a separator).

n: CH2=CHCOOM. Usually used to make polypropylene copolymer.

n: 1. a state or county tax based on the value of a property. 2. tax imposed at a percent of a value.

n: Schlumberger wireline tool that measures phase shift and attenuation of a 1100 MHz wave. Used for Hydrocarbon identification independent of formation water salinity, thin bed detection, Hydrocarbon saturation and mobility and to evaluate invaded zones.

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 new set of journal bearing insert bit presented by America Hughes Company. It has the longer life and higher ROP than many kinds of former bits.
