Abstract: 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.

Abstract: A process may include providing heat from one or more heaters to at least a portion of a subsurface formation. Heat may transfer from one or more heaters to a part of a formation. In some embodiments, heat from the one or more heat sources may pyrolyze at least some hydrocarbons in a part of a subsurface formation. Hydrocarbons and/or other products may be produced from a subsurface formation. Certain embodiments describe apparatus, methods, and/or processes used in treating a subsurface or hydrocarbon containing formation.

Abstract: A method for monitoring fluid properties with a distributed sensor in a wellbore having an inner surface, a top and a bottom comprising causing the distributed sensor to assume a helical shape, pulling the distributed sensor towards the bottom of the wellbore, while retaining the helical shape of the distributed sensor, feeding the distributed sensor into the wellbore so that the distributed sensor is in substantially continuous contact with the inner surface, and allowing the distributed sensor to become at least partially supported by friction at the inner surface.

Abstract: Methods for determining a preferred application of a plurality of transducers or sensors to a structure are disclosed for monitoring and imaging deformation of the structure as it is subjected to various forces.
