Abstract: An electromagnetic energy transmitter is provided for induced polarization logging with a borehole to surface electromagnetic (BSEM) transmitter. The transmitter is lowered into a well borehole to a desired location in a well borehole to emit electromagnetic energy for the surveys. The transmitter affords more accurate measurements of its position in the well borehole. The transmitter also senses pressure and temperature conditions at its borehole location to provide indications of detected potential problems in the well from the survey or other sources, and to reduce risks and enhance safety and quality of the operations.

Abstract: An electromagnetic energy transmitter is provided for induced polarization mapping with a borehole to surface electromagnetic (BSEM) transmitter. The transmitter is lowered into a well borehole to a desired location in a well borehole to emit electromagnetic energy. An array of receivers spaced over an area of the earth surface senses the induced polarization response to the emitted electromagnetic energy in areas of interest for mapping. Maps are formed of the induced polarization responses sensed by the array of receivers.
