    A breakthrough in fracturing. A new hydraulic fracturing fluid increases production without using water resources

    GASFRAC?s LPG Fracturing Process
    Oil and gas producers use fracturing to increase the conductivity of an oil or gas zone within a reservoir to improve production and recovery of hydrocarbons.

    The most common reservoir stimulation is hydraulic fracturing, whereby viscous fluid with suspended proppant (grains of quartz sand or ceramic material) is pumped through the wellbore and into the reservoir zone that is being stimulated. Proppant and fracturing fluid are mixed in a blender and then pumped into a well that penetrates an oil or gas bearing formation. As high pressure is applied to the well, the formation fractures and proppant carried by the fracturing fluid flows into the fracture. The deposited proppant holds the fracture open after pressure is relaxed and production is resumed.

    Each fracture treatment is individually designed to take account of the specific temperatures, pressures, formation permeability, and reservoir fluids expected in the producing zone in which fracturing will be performed. The fracturing fluid must have a sufficient viscosity to carry the proppant into the fracture, should minimize formation damage and must be safe to use. A fracturing fluid that remains in the formation after fracturing is not desirable since it may block pores and reduce well production.
