UNBRIDLED RESOURCES LLC KNOWLES 21 18 25 1H - Oil Extraction Facility near Arnett, Oklahoma

The KNOWLES 21 18 25 1H facility, operated by UNBRIDLED RESOURCES LLC, is an oil extraction site located approximately 0.9 miles west of the intersection of E0680 Road and N1760 Road near Arnett, Oklahoma. Situated in Ellis County, this facility is part of the extensive oil and gas infrastructure in the Anadarko Basin, a prolific hydrocarbon-producing region. The site is currently operational and classified under NAICS codes 211111 (Crude Petroleum Extraction) and 211120 (Natural Gas Liquid Extraction), indicating its role in both oil and associated gas production. As an oil extraction facility in Oklahoma, the KNOWLES 21 18 25 1H operates under the regulatory framework of the Oklahoma Corporation Commission (OCC) and the U.S. Environmental Protection Agency (EPA). The EPA's Clean Air Act regulations, including New Source Performance Standards (NSPS) for oil and gas operations, govern emissions from equipment such as storage tanks, separators, and compressors. Additionally, the facility must comply with state-level rules on well construction, hydraulic fracturing, and water management. Horizontal drilling and multi-stage hydraulic fracturing are typical technologies used in this region to access oil from tight formations. Environmentally, oil extraction facilities like KNOWLES 21 18 25 1H are associated with potential risks including groundwater contamination from well casing failures, surface spills of produced water or crude oil, and air emissions of volatile organic compounds (VOCs) and methane. The site's location in a rural area of Ellis County means it is subject to state and federal oversight to minimize impacts on local water resources and air quality. The facility's operational status underscores its ongoing contribution to domestic oil supply, supporting energy demands while operating within established environmental safeguards.

The facility is situated in the semi-arid High Plains region of Oklahoma, where water resources are critical for agriculture and ecosystems. Oil extraction activities can pose risks to groundwater through improper well construction or surface spills of produced water, which often contains high salinity and trace metals. Air emissions from equipment and flaring contribute to local ozone formation and greenhouse gas emissions. Regulatory compliance with EPA's NSPS and OCC rules aims to mitigate these impacts, but the cumulative effect of multiple wells in the area requires ongoing monitoring.
