Thousands of feet underground, oil and natural gas resources are often contained in the pores of sedimentary rocks. To access these resources, wells are drilled into the hydrocarbon-bearing rock formations. Sometimes oil and gas can be extracted easily, while other times these resources can be difficult to produce. For these difficult reservoirs, it is common for industry to utilize a process called hydraulic fracturing. This technology is used to enhance the productivity of wells by injecting water, sand, and additives underground at high pressures to create fractures in the rock bodies containing oil and gas. Creating fractures in the rock provides a pathway for those resources to travel to the well bore. Hydraulic fracturing has allowed for the rapid development of new unconventional plays across the nation.
