Patent number: 6525003Abstract: A well logging fluid is provided having a relatively non-conductive fluid and an effective amount of a salt sufficient to modify the electrical characteristics the relatively non-conductive fluid resulting in a modified fluid or well logging fluid such that an electrical well-logging tool when disposed in the modified fluid can perform an electrical well-logging survey of a borehole containing the modified fluid. The non-conductive fluid is selected from the group consisting of a non-aqueous fluid and an invert emulsion of an aqueous phase in a non-conductive liquid. In an invert emulsion, the aqueous portion thereof ranges up to about 70 percent by volume. The salt has a cation and an anion, wherein the cation is selected from the group consisting of divalent and trivalent metal cations capable of forming a complex, and the anion is one that disassociates from the cation in an aqueous medium.Type: GrantFiled: April 8, 1998Date of Patent: February 25, 2003Inventors: Robert P. Schlemmer, Edward Keith Morton

Patent number: 6006831Abstract: A well logging fluid is provided having a relatively non-conductive fluid and an effective amount of an electrically conductive fiber sufficient to modify the electrical characteristics of the relatively non-conductive fluid resulting in a modified fluid or well logging fluid such that an electrical well-logging tool when disposed in the modified fluid can perform an electrical well-logging survey of a borehole containing the modified fluid. The non-conductive fluid is selected from the group consisting of a non-aqueous fluid and an invert emulsion of an aqueous phase in a non-conductive liquid. In an invert emulsion, the aqueous portion thereof ranges up to about 70 percent by volume. Preferably, the modified fluid or well logging fluid has an electrical stability of at most 350 volts, more preferably at most 250 volts, as measured according to API RB 13-2. The well logging may be used for electric well logging and imaging.Type: GrantFiled: September 12, 1997Date of Patent: December 28, 1999Assignee: Schlumberger Technology CorporationInventors: Robert P.
