The project involves E&B Natural Resources Management Corporation performing a sidetrack operation on the Phippen 15 well (API #0402948670) in the Antelope Hills Oil Field, Kern County, California. The work includes cleaning the original wellbore to a depth of 2,816 feet, cementing to 500 feet, tagging the cement surface, and sidetracking to drill a new 6-1/4 inch hole to 4,000 feet. A 5-1/2 inch combination casing string with a lower-slotted production section will be run and cemented to restore well productivity, with potential plugback operations as necessary. The well will remain classified as an oil and gas producer. Regulatory approval is being sought through the California Department of Conservation, Geologic Energy Management Division (CalGEM), under categorical exemptions from the California Environmental Quality Act (CEQA), specifically Class 1 (existing facilities), Class 2 (replacement/reconstruction), and Class 4 (minor alterations to land), with compliance to CalGEM regulations 14 CCR §§ 1684.1 and 1684.2. No federal contract clauses, pricing data, delivery schedules, or procurement evaluation factors are included, as this is solely an environmental compliance notice for a state-regulated oilfield operation.
