Abstract

Seismic apparatus for generating a seismic signal in a subterranean substrate comprises a body with a hammer piston for impacting the substrate, and wherein the hammer is moved by a hydraulic pressure differential, typically driven by an energy stored within an accumulator device within the body. The accumulator is typically a spring which in a compressed state is arranged to apply pressure to the fluid on the first end of the piston chamber, and thereby drive it toward the wall of the substrate.
