Hydraulic fracturing involves safely tapping shale and other tight-rock formations by drilling a mile or more below the surface before gradually turning horizontal and continuing several thousand feet more. Thus, a single surface site can accommodate a number of wells. Once the well is drilled, cased and cemented, small perforations are made in ...Web

Hydraulic fracturing involves forcing a liquid under high pressure from a wellbore against a rock formation until it fractures. The injected fluid contains a proppant—small, solid particles, usually sand or a man-made granular solid of similar size—that wedges open the expanding fractures. The proppant keeps the fracture open, …Web

Oil and gas operators have used acid treatment (acidizing) to improve well productivity for almost 120 years. Acidizing predates all other well stimulation techniques, including hydraulic fracturing which was not developed until the late 1940s. However, until the early 1930's, acidizing use was limited by the lack of effective acid corrosion ...Web
