Abstract: A method for generating self-propped hydraulic fractures. In one embodiment, the method comprises injecting three fluid stages sequentially, each with successively higher viscosity, comprising a pad, a sealing slurry, and a displacement fluid which may be referred to as a sweep. Compositions of each of the three fluid stages are provided, each of which may be selected based upon characteristics of the formation being treated or upon one or more characteristics of the desired fracture.

Abstract: A method for improving oil and gas well productivity includes introducing a lubricating agent into a microfracture in a subterranean formation, coating at least a portion of a first surface and a second surface of the microfracture with the lubricating agent to produce a coated microfracture; and, providing a sufficient time for the coated microfracture to close. The introducing, the coating and the providing cause the first surface and the second surface of the coated microfracture to misalign after the closure of the coated microfracture and an opening to form between the first surface and the second surface. An encapsulated lubricating agent includes 30 to 50 wt % of a lubricating agent, and 50 to 70 wt % of an encapsulant encapsulating at least a portion of the lubricating agent.

Abstract: The disclosure relates to catalysts that include a fibrous silica support and a plurality of metal oxide nanoparticles including iron oxide and nickel oxide, and methods of making and using such catalysts. The fibrous silica support is a particle with radially extending fibers. The catalyst can used to convert methane into hydrogen gas. The catalysts can be introduced into an underground formation, such as with a fracking fluid, for in-situ methane conversion.

Abstract: Methods and fracturing fluids for fracturing a subterranean formation using in situ proppant particulates. Methods include introducing a fracturing fluid into a subterranean formation at or above a fracture gradient. The fracturing fluid includes a non-phase-transition fluid comprising at least an aqueous fluid and a surfactant; and a phase-transition fluid comprising a phase-change material selected from the group consisting of styrene monomers, methyl methacrylate monomers, or a combination of styrene monomers and methyl methacrylate monomers, an initiator, and an optional accelerator.

Abstract: The present invention relates to an autonomous chemical treatment system and method for drilling and completion probes, so that it allows the probe to carry out chemical treatments in subsea wells, dispensing the need to use the WSSV, which has a limited treatment capacity due to tank volumetry, generally smaller that the marine probes.

Abstract: A method of repairing a well is provided. The method includes injecting a brine solution into the well, injecting carbon dioxide into the well, and reacting the brine solution in the reservoir rock with the carbon dioxide to form calcite such that calcite precipitates into the desired flow path between a cold well and a hot well to effectively repair short circuits within the EGS reservoir.

Abstract: A composition and method for hydraulically fracturing an oil or gas well to improve the production rates and ultimate recovery using a porous ceramic proppant infused with a chemical treatment agent is provided. The chemical treatment agent may be a tracer material that provides diagnostic information about the production performance of a hydraulic fracture stimulation by the use of distinguishable both water soluble and hydrocarbon soluble tracers. The tracer can be a biological marker, such as DNA. The porous ceramic proppant can be coated with a polymer which provides for controlled release of the chemical treatment agent into a fracture or well bore area over a period of time.

Abstract: A novel surfactant composition that comprises of two surfactant components, a solvent, and water. The surfactant composition is added to a fracturing fluid, which is then pumped downhole into a subterranean formation where the novel characteristics of the fracturing fluid lend to improved oil production over the fracturing fluid without the surfactant composition.
