Abstract: A subterranean zone can be treated by introducing a mixture of an acid-generating material and a proppant (for example, in a pad fluid or a pre-pad fluid) to the subterranean zone. Fractures and microfractures are created in the subterranean zone using the mixture of the acid-generating material and the proppant. The proppant is positioned within the fractures and microfractures to keep them open.

Abstract: Systems for determining hydraulic fracture geometry and/or areal extent of an area of interest in a reservoir, are provided. An embodiment of a system can include downhole acoustic receiver equipment isolated from fracturing operations in a lower portion of a first wellbore, and fracturing equipment located in a second wellbore connected to the first wellbore. Communications between surface equipment in the downhole acoustic receiver equipment is provided through a communications conduit bypass that permits well operations in the second wellbore without interfering with communications between the surface equipment and the downhole acoustic receiver equipment.

Abstract: Distinctive and analytically distinguishable water-soluble and oil-soluble tracer compositions are applied as coatings to the exterior surface of one or more lengths of production tubing installed in a horizontal well bore between open-hole packers adjacent one or more inflow control devices, (ICD), whereby water and/or oil contacting one or more of the respective tracer coatings and passing a faulty open-hole packer seal will solubilize the tracer coating(s) and be detectable by appropriate tests on the produced water and/or hydrocarbon fluids at the earth's surface.

Abstract: A method for detecting in real time the growth of a hydraulic fracture in an impermeable subterranean zone separating a monitored subterranean zone and an injection subterranean zone, which zones are penetrated by a wellbore, whereby a pressure sensor is positioned in pressure sensing communication with the first subterranean zone, and the pressure sensor is monitored for a pressure increase in the first subterranean zone, the pressure increase being indicative of a hydraulic fracture extension from the second subterranean zone through the impermeable zone to the first subterranean zone.
