n: a substance having marked basic (alkaline) properties, such as a hydroxide of an alkali metal. See base.

n: Any compound having pH properties higher than the neutral state.

a strongly basic solution.

n: the pressure exerted by a specific number of molecules contained in a specific volume (usually I cubic foot) at a specific temperature. Base pressure is a factor used in calculating gas volume. Standard base pressure varies from state to state. In Texas, for example, base pressure is 14.73 psia at 6().F. In Louisiana, base pressure is 15.025 psia at 6()ﾰF. base price II: the value of natural gas, usually at the wellhead, before any imposition of taxes, gathering, compression, or other charges, as stated in a gas sales contract. basicity II: pH value above 7 and the ability to neutralise or accept protons from .:ids.

bicarbonate of soda, used in acid neutralization operations.

n: (HAZWOPER) an operation during which hazardous substances are removed, contained, incinerated, neutralised, stabilised. cleaned up, or in any other manner processed or handled. with the ultimate goal of making the site safer for people or the environment.

n: the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation.

n: (1) The process of thinning the drilling fluid by bonding with (neutralizing or covering) the positive electrical charges of drilling fluid additives to prevent one particle of drilling fluid from being attracted to another particle. (2) Breakup of flocs

dispersing a clump or a gathering or “flocculated” of particles. Usually accomplished by dispersants or solvent thinners.

n: In drill fluid, in order to keep electric neutrality the clay colloids which carry negative charge must attract the same number of cations.As a result,an electric layer forms in the interface between Solid and liquid. Some cations

n: the process by which a neutral atom becomes positively or negatively charged through the loss or gain of electrons.

n: 1. position of the rigs weight indicator where hook load is zero.2. position of an engines transmission when the engines flywheel or other power transmission device is not being turned by the engine.

n: a packer that, unlike compression or tension packers, requires neither set-down weight nor ups train pull to remain set.
