摘要： The method includes the introduction of a proppant-free stage and a proppant laden stage into the wellbore and/or subterranean formation. The method increases the effective fracture width and enhances fracture conductivity within the formation. Either the proppant-free stage or the proppant laden stage contains a breaker. At least one of the proppant-free stage or proppant laden stage contains a viscosifying agent to which the breaker has affinity. The viscosifying agent may be a superabsorbent, a viscosifying polymer (other than a superabsorbent) or a viscoelastic surfactant. The breaker has greater affinity for the viscosifying agent not present in the same stage as the breaker. Either the proppant-free stage or the proppant laden stage may be foamed.

摘要： A method of approximating or determining at least one dimension or other characteristic of at least one underground geological feature in a zone of interest proximate to a well bore includes generating an electric field in the zone of interest. At least two sensing electrodes are provided in the well bore and configured to detect differences therebetween in electric potential caused by at least one target object in the zone of interest. Proppant containing signal generating devices (SGD) is delivered into the geological feature(s). The SGD generate a detectable signal in response to at least one downhole condition or property. At least one receiver receives the detectable signals and provides data relating thereto. At least one dimension or other characteristic of the geological feature is approximated or determined based at least partially upon data provided by the sensing electrodes and receiver(s).

摘要： Subterranean formations, such as tight gas formations, may be subjected to hydraulic fracturing by introducing into the formation a fracturing fluid of an aqueous fluid, a hydratable polymer, a crosslinking agent and proppant. The fracturing fluid is prepared in a blender and then pumped from the blender into the wellbore which penetrates the formation. The fluid enters the reservoir through an entrance site. The apparent viscosity of the fluid decreases distally from the entrance site such that at least one of the following conditions prevails at in situ conditions: (a) the apparent viscosity of the fracturing fluid 100 feet from the entrance site is less than 10 percent of the apparent viscosity of the fracturing fluid at the entrance site; (b) the apparent viscosity of the fracturing fluid 15 minutes after introduction into the entrance site is less than 15% of the apparent viscosity of the fracturing fluid at the entrance site; or (c) the apparent viscosity of the fracturing fluid is less than 10 cP within 15 minutes after being introduced through the entrance site.

Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments.

摘要： A cement composition is provided including a cement and a low reactivity particle coated with a swellable polymeric material. The low reactivity particle is coated with a swellable polymeric material at a concentration of about 10 weight percent to about 50 weight percent, based on the weight of the cement. The swellable polymeric material swells to a larger volume when exposed to one or more hydrocarbons, depending on the selected polymeric material. The cement composition is used in a method as a self-sealing cement for cementing an oil and gas well, thereby minimizing or mitigating the unwanted migration of water or hydrocarbons.

摘要： A method for pre-emptively reducing the production of water in an oil and gas well is provided. In one embodiment, a drill-in fluid having a relative permeability modifier (RPM) capable of impeding the production of water is introduced into the wellbore during drilling operations. In a second embodiment, a completion fluid having a relative permeability modifier (RPM) capable of impeding the production of water is introduced into the wellbore during completion operations. The drill-in fluid or completion fluid may further include an organosilicon compound to increase flow resistance and extend the effective RPM permeability application range.
