摘要： A wellbore fluid having a non-aqueous continuous liquid phase that exhibits an electrical conductivity increased by a factor in order of 104 to 107 compared to conventional invert emulsion comprises from about 0.2% to about 10% by volume of carbon black particles and one or more emulsifying surfactant(s) selected from the class including nonionic emulsifiers of Hydrophilic-Lipophilic Balance (HLB) less than about 12, and anionic surfactants wherein the counter-ion (cation) is any of alkali metal, ammonium, or hydrogen ions. This wellbore fluid can be used for drilling or completing a well and can be used for providing enhanced information from electrical logging tools, measurement while drilling, logging while drilling, geosteering and the like.

摘要： A method is provided for detecting a junction between adjacent can ends which are arranged in a stack. The method enables a selected number of can ends in the stack to be counted. The method comprises the steps of illuminating the peripheral edge regions of can ends in the stack with a signal emitted by a emitter inclined at an oblique angle to a line normal to the central axis of the stack and detecting reflected signals from the ends of the peripheral edge regions of the can ends. Oblique illumination provides alternating regions of the stack reflecting a relatively high and relatively low light intensity. Detection of the light intensity across the length of the stack enables a junction between adjacent can ends to be determined.
