More Information
Summary:An apparatus for loading fluid into subterranean formations includes a housing, a sleeve slidably disposed within the housing, a piston defining an interior volume, the piston slidably disposed within the sleeve and within the housing such that a fluid pressure within the interior volume causes the sleeve to oscillate relative to the housing and causes the piston to oscillate relative to the sleeve and the housing, and a pump which is operably associated with the piston such that the fluid pressure from the interior volume is intensified in the pump and injected into the formation as the piston oscillates relative to the housing.
