Question

Quizplus · Accepted Answer

Hydraulic fracturing, also known as fracking, is a technique used to extract oil and natural gas from shale rock formations. The process involves injecting water, sand, and chemicals into the shale rock under high pressure, which creates small fractures or cracks, allowing the oil and gas to flow into the wellbore and be extracted. Sandstone, slate, granite, and limestone are not typically used for hydraulic fracturing.
