  • Patent number: 7938185
    Abstract: A hydraulic fracturing process consisting essentially of drilling a wellbore through at least one reservoir formation, installing in said wellbore at least one conduit, ensuring pressure communication between said wellbore and said reservoir formation, at a higher effective stress formation, selecting the location of the pressure communication between the wellbore and the reservoir formation for control of said hydraulic fracturing process and pumping a hydraulic fracturing treatment comprising a fracturing fluid and a proppant, at a sufficient pressure via said conduit to create at least one fracture in the higher effective stress formation. In addition, processes for increasing conductivity near a wellbore and producing fluids from a lower effective stress permeable formation via a fracture extending from the higher effective stress fracture formation into the lower effective stress permeable formation may include applying several approaches to packing or filling fractures with proppant.
