Abstract: Techniques for treating a hydrocarbon reservoir include delivering a composition to the hydrocarbon reservoir. The composition includes at least one acid, and liquid or supercritical carbon dioxide (CO2). The method further includes exposing the delivered composition to water to activate the composition; and treating a rock formation of the hydrocarbon reservoir with the activated composition.

Abstract: Systems and methods for selectively reducing water production in a well. The interior of the well casing is in fluid communication with a subterranean formation with a hydrocarbon-producing zone and a water-producing zone. The subterranean formation has a switchable polymer in contact with at least one of the hydrocarbon-producing zone and the water-producing zone. The switchable nature of the polymer enables a hydrophobic state and a hydrophilic state and fluid communication between the water-producing zone and the interior of the well casing is greater when the polymer is in its hydrophilic state than when the polymer is in its hydrophobic state. In its hydrophilic state, more of the polymer will invade the water-producing zone but the plugging action will not take place until it is switched to the hydrophobic state.

Abstract: A method of stimulating petroleum production includes introducing a fracturing fluid into a petroleum formation, thereby creating at least one fracture to stimulate the petroleum production. The fracturing fluid is introduced into the petroleum formation at a pressure above the breakdown pressure of the formation. The fracturing fluid includes a plurality of proppants where from 1 to 50 wt. % of the plurality of proppants includes micro proppants having a particle size ranging from 0.5 to 150 μm, and from 50 to 99 wt. % of the plurality of proppants includes macro proppants having a particle size greater than 100 mesh.

Abstract: Unconventional hydrocarbon source rock reservoirs can contain the organic material kerogen, intertwined with the rock matrix. The kerogen can alter the tensile strength of the rock and contribute to higher fracture energy needs. To degrade kerogen and other organic materials, oxidizing gasses are dissolved in carbon dioxide (CO2) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the CO2 or generated in situ using precursors.
