Well fracturing method employing a liquefied gas and propping agents entrained in a fluid
Patent
·
OSTI ID:6094758
A method is provided of well stimulation with little or no reservoir contamination and a high percentage of load fluid recovery. A liquefied gas and a fluid containing entrained propping agents are injected into the formations. Since the 2 fluid phases are completely miscible, they may be either blended prior to well entry, or injected separately, and blended in the well. The fluids are injected until a fracture of sufficient width to produce a highly conductive channel has been formed. Particles of the propping agent, suspended in the mixture are carried into the fracture. The injected fluid is then permitted to leak off into the formation until the fracture has closed sufficiently to hold the particles in place. (14 claims)
