Check Valves for Oil & Gas Wells and Produced Water
With close to 1 million producing oil and natural gas wells in the United States, the industry generates approximately 60 million barrels of produced water daily. This water originates from subsurface reservoirs during the extraction process, where it mixes with oil and gas and emerges at the surface. It can also include water injected into drill rigs or flowback water from hydraulic fracturing operations. Proper handling and disposal are essential to maintain operational efficiency and environmental compliance.
Saltwater disposal (SWD) is an essential process in the oil and gas industry, managing produced water, a byproduct of extraction operations. Often referred to as saltwater, this water is considered a waste product that is characterized by high salinity and may contain hydrocarbons, heavy metals, and other contaminants. The SWD process often includes pre-treatment steps, such as removing solids and separating residual hydrocarbons, to protect the integrity of the disposal wells. It is then injected into deep underground formations through regulated Class II disposal wells, ensuring it cannot contaminate other subsurface layers and drinking water supplies.
