ABSTRACT:
A well fracturing system in which a fracturing fluid storage vessel, high pressure pump and high pressure conduit are connected in series to a well. A pressure vessel is connected to the high pressure conduit for injecting proppant carrying fracturing fluid into the well without the proppant carrying fracturing fluid passing through the high pressure pump. The pressure vessel may be formed of a pipe with a free floating piston dividing the pressure vessel into a drive side and driven side. Proppant carrying fracturing fluid is stored in the driven side, and may be emplaced within the pressure vessel at a remote site from the well. Drive fluid is injected into the drive side to force the proppant carrying fracturing fluid into the high pressure conduit and down the well. The drive fluid may be a diverted portion of fracturing fluid pumped by the high pressure pumper. Several pressure vessels may be used in parallel, and proppant may be stratified in the pressure vessel.
