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 (CO) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the COor generated in situ using precursors.
