n pi: a group of polymers that can maintain or increase the viscosity of bentonite while flocculating other clay solids in the mud. With bentonite extenders, desired viscosity can often be maintained using only half the amount of bentonite that would otherwise be required.

n: C6H6 colourless, volatile, flammable toxic liquid aromatic hydrocarbon used as a solvent and as a motor fuel.

an aromatic (cyclic or ring structure) compound, present in very minor quantities in many crude oils.

n: the structural arrangement of atoms believed to exist in benzene.

a common diverter. It can sublime, or go directly from a solid to a gas.

v: to make a gift of personal property by means of a will. Compare devise. Bernoullis theorem n: a mathematical expression of the conservation of energy in streamline flow;the theorem states that the sum of the ratio of the pressure to the mass density, the product of the gravitational constant and the vertical height. and the square of the velocity divided by 2 are constant.

a quarried sandstone with from 4500 to 9000 psi UCS, used commonly in laboratory flow testing.

the equation is used in the design of chokes and explains the manner in which pressure in the body in the body of the choke, downstream of the first pressure drop, is lower than the eventual recovery pressure at the end of the choke.

n: (BACT) an air emission standard of technology determined by the states on a case-by-case basis. The BACT is applied in attainment areas that meet or exceed NAAQS. and states can consider cost and economic impact when determining exactly what the BACT is and how it will be applied in a specific case.
