Waterless hydraulic fracturing with on-site fluid treatment

Summary

Hydraulic fracturing has emerged as an economical method to collect tight oil deposits and natural gas by injecting high-pressure fluids underground to induce cracks in deep shale formations. The most commonly used fluid is a mixture of water, chemicals, and proppant materials. However, the fluid may become contaminated by metal sources from the surrounding environment, and the use of water-based fracturing fluids imposes a heavy demand on the local water supply. This technology is a method for waterless hydraulic fracturing that uses supercritical carbon dioxide to induce fracture in conjunction with functionalized proppant materials to immobilize metal contamination. This technique may thus be used as a sustainable method of hydraulic fracturing that reduces environmental contamination and reliance on water supply.
