METHOD OF FRACTURING AN EARTH FORMATION, EARTH FORMATION BOREHOLE SYSTEM, METHOD OF PRODUCING A MINERAL HYDROCARBON SUBSTANCE

摘要

Method of fracturing an earth formation by pumping a pressurized fracturing fluid into a borehole in an earth formation thereby fracturing the earth formation. At least during the pumping, a strain distribution is monitored in an object that is located in the earth formation and that is mechanically interacting with the earth formation. The borehole system has a plurality of strain sensors for monitoring the strain distribution in the object during fracturing. After terminating the pumping of the pressurized fracturing fluid, mineral hydrocarbon fluids may be allowed to flow from the reservoir into the wellbore or another wellbore, and produced via that wellbore.
