1. A downhole reservoir stimulating tool to be run on a drill string, the tool comprising:
an outer housing,
an inner mandrel disposed within the outer housing and configured to move parallel relative to the outer housing,
an electromagnetic flowmeter disposed within the outer housing and configured to temporarily restrict downward movement of the inner mandrel, resulting in compressional strain energy derived from compressing drill string tubulars of the drill string above the tool, and
an inner mandrel piston coupled to the inner mandrel, configured to convert the compressional strain energy of the drill string tubulars into a high-pressure fluid wave that propagates down the drill string and further propagated into the subsurface formation causing cracks and fractures, enhancing the permeability of the subsurface formation and consequently the production of fluids.
