The clay is usually a combination of native clays that are suspended in the fluid while drilling, or specific types of clay processed and sold as additives for the WBM system. The most common type is bentonite, called "gel" in the oilfield. The name likely refers to the fluid viscosity as very thin and free-flowing (like chocolate milk) while ...
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
The drilling fluid flowing over the shaker bed is designated into two categories: Pool: Which is the area of the screening deck that consists mostly of drilling fluid with drilled cuttings suspended within it. Beach: Is the area where the fluid has been mostly removed from the cuttings and they begin to look like a pile of solids.
This may be done by injecting fluids at high pressure (hydraulic fracturing), injecting fluids laced with round granular material (proppant fracturing), or using explosives to generate a high pressure and high speed gas flow (TNT or PETN up to 1,900,000 psi (13,000,000 kPa) ) and (propellant stimulation up to 4,000 psi (28,000 kPa) ).

Drilling and hydraulic fracturing have made the United States a major crude oil exporter as of 2019, [11] but leakage of methane, a potent greenhouse gas, has dramatically increased. [ 12 ] [ 13 ] Increased oil and gas production from the decade-long fracking boom has led to lower prices for consumers, with near-record lows of the share of ...

Drilling fluids are necessary for drilling deep holes, so the cable-suspended drills that are used for these projects use a pump to provide fluid circulation, in order to remove the cuttings from the bit. [37] A few drills designed for use with drilling fluid also have auger flights on the inner barrel. [108]
