Abstract
The present disclosure relates to generating electricity downhole using a mud-operated pulser. A disclosed example embodiment of a mud pulser system includes a piston assembly movably disposed within a housing, comprising a power piston, and configured to move in response to a pressure from a fluid flow, a control valve having an open state, in which the power piston receives the fluid flow, and a closed state, in which the power piston does not receive the fluid flow, a magnet disposed on the housing or the piston assembly, and a coil disposed on the housing or the piston assembly, wherein the magnet is configured to displace relative to the coil in response to movement of the piston assembly within the housing, such that relative movement of the magnet and the coil generates electrical energy.
