n: The voltage when emulsion begins to demulsify under the certain condition. A target used to measure stability of emulsion.

n: a wellbore in which casing has been run.

n: The portion of the wellbore that has had metal casing placed and cemented to protect the openhole from fluids, pressures, wellbore stability problems, or a combination of these.

n: The nature that disperse phase particle of colloid system whether is easy to agglomerate or not.

n: a chart of successive meter factors (or relative meter errors) generally plotted as a function of time. Used to evaluate meter stability and to determine when meter performance has departed from its normal range.

n: the quality of being corrosive. cosurfactant n: a surfactant, generally an alcohol, added to a micellar solution to adjust the viscosity of the solution, maintain its stability, and prevent adsorption of the main surfactant by reservoir rock.

n: Schlumberger wireline tool that records shear, compressional and stoneley waveforms. Used for amplitude variation with offset (AVO) calibration, shear seismic correlation, wellbore stability measurements, sanding analysis, fracture height estimation and s

n: the diamond bit whose length of gauge protection is greater than ordinary length of gauge protection in order to improve the stability during drilling further

one of several materials that reduce the stability of the bubble skin in a foam and cause the foam to break.

n: the degree of fluctuation of well wall during drilling ,the effect factors including not only the character,indensity and structure stress of rock but also fluid character,polishing of drilling pipe and other external anency
