Patent abstract

A power source for use in a downhole environment. The power source can include a microgenerator, where the microgenerator is comprised of a motive source, a rotor, a stator, and an electrical load. The motive source can be compressed gas, liquid, two-phase fluid, or combustion gases. The rotor may comprise a magnet and the stator may comprise a coil, such that rotating the rotor coaxially proximate to the stator produces electrical current. The electrical load includes any device used in downhole exploration and production that requires electrical energy.
