ABSTRACT:
An apparatus for generating acoustic source energy in a liquid medium. A slotted cylinder has an interior volume filled with a fluid. An actuator selectively pressurizes the fluid to expand the slotted cylinder. Movement of the slotted cylinder due to expansion and contraction generates a pressure pulse in the liquid medium to create acoustic source energy. The device provides an acoustic source for marine seismic operations and for use downhole in a borehole.
