Fracture Stimulation Of Layered Reservoirs

摘要

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 said pressure communication between said wellbore and said 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 said higher effective stress formation. Also disclosed are 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.
