1. What is the short term for HYDRAULIC FRACTURING? Fracking is a slang term for hydraulic fracturing, which is the process of creating fractures in rocks and rock formations by injecting specialized fluid into cracks to force them to open further.

2. What is hydraulic fracturing? Hydraulic fracturing is an oil and gas production technique used in tight geologic formations that involves horizontal directional drilling of wells as well as the use of water, sand and chemicals at high pressures to fracture rock and release hydrocarbons.

3. What is the average depth of a well for Hydraulic fracturing? The median depth of hydraulic fracturing was 8180 ft (2490 m) and the mean depth was 8290 ft (2525 m). Approximately 25% of the hydraulic fracturing operations were deeper than two miles and the 90th percentile of the depth observations was 11 900 ft (3610 m)

4. What does a fracturing fluid contain? They include: dilute acids, biocides, breakers, corrosion inhibitors, crosslinkers, friction reducers, gels, potassium chloride, oxygen scavengers, pH adjusting agents, scale inhibitors, and surfactants.

5. What are the main stages of hydraulic fracturing process? Perforation: Perforations are made at a suitable depth along the horizontal production casing, also known as pay zones. Injection: Fracking fluid is injected into the reservoir at very high pressures, which creates fissures in hydrocarbon-bearing rocks and releases the products.

6. What are the possible bad effects of hydraulic fracturing? The environmental impact of hydraulic fracturing is related to land use and water consumption, air emissions, including methane emissions, brine and fracturing fluid leakage, water contamination, noise pollution, and health. Water and air pollution are the biggest risks to human health from hydraulic fracturing.
