Pulsed power allows to extend the measurement range of logging tools well into virgin formation, allowing MPI tools to measure formation properties unaffected by drilling damage or invasion by drilling fluids.
Power is defined as the rate at which energy is used over a period of time.
The customary unit of energy is the joule, and the unit of power is the watt. Energy used at the rate of one joule per second requires a power level of one watt. Downhole tools commonly draw electrical power through the wireline from a surface power source. Power levels are limited to less than 600 watts because of the resistance of the wireline, which is typically 25,000 feet long. A conventional induction tool directly uses the available power to drive a magnetic transmitting coil at a frequency of 20 kHz.
