the viscosity of the fluid in the reservoir at the reservoir conditions. Note – associated gas reduces the viscosity of most oils.

n: a kind of well control method of experimental volume

n: 1. an instrument or assembly of instruments used to measure torque and other force-related properties of rotating or reciprocating machinery. 2. in sucker rod pumping, a device used to indicate a variation in load on the polished rod as the rod string reciprocates. A continuous record of the result of forces acting along the axis of the polished rod is provided on a dynamometer card, from which an analysis is made of the performance of the well pumping equipment.

a recording of the stresses in a rod string of a beam pumping unit.

demigration to zero offset. An improvement in seismic processing over dip movement offset where signal velocity varies significantly with depth.

n: boiling, especially as applied to a system to remove heat from engine jacket water, wherein the water is permitted to boil and the evolved vapours are condensed in air-fin coolers.

n: the drilling pressure needed when the power of turbine in the bottom reach the maximum value during turbine drilling

n: the percentage of the bulk volume of a rock sample that is composed of interconnected pore spaces that allow the passage of fluids through the sample. See porosity.

interconnected, drainable porosity.

n: the turbine rotate speed needed when the power of turbine in the bottom reach the maximum value during turbine drilling
