Abstract: Abstract Compared with conventional water-based fracturing, the supercritical CO2 (SC-CO2) fracturing technology can potentially improve the fracturing effect and gas production in unconventional tight reservoirs. To comprehend the key mechanical mechanism of this technology, some… read more here.
