  • Conductive medium for openhole logging and logging while drilling
    Patent number: 6308788
    Abstract: A method of electrically logging subterranean wells using a conductive fluid in which the conductive fluid includes a miscible combination of an oleaginous fluid, a polar organic solvent, and an electrolytic salt. The electrolytic salt or brine of the salt is present in a concentration sufficient to permit the electrical logging of the subterranean well. The medium may further include gelling agent, weight material, surfactant, or corrosion inhibitors. The polar organic solvent may preferably be a oil soluble glycol or glycol ether such as ethylene glycol, diethylene glycol, propylene glycol, polypropylene glycol, and the like.
