STEAMBOAT SPRINGS, Colo., Oct. 27, 2025 /PRNewswire/ -- Three Crown Petroleum LLC ("Three Crown" or the "Company") a Colorado-based oil and gas exploration and production company, today announced that the Irvine 1NH well is currently producing at a strong initial average flow rate of approximately 752 barrels of oil equivalent per day (boe/d) with a high oil cut of approximately 82%. The Irvine 1NH well was placed on production on October 14, 2025, marking significant progress in the Company's Powder River Basin horizontal drilling program in Johnson County, Wyoming. The well was drilled to approximately 22,500 feet and completed in the highly prospective Niobrara horizon. The Irvine 1NH well featured a two-mile horizontal leg and was completed with 51 frac stages spaced approximately 200 feet apart.

"We are excited to announce a very strong initial flow rate from the Irvine 1NH well. The high oil cut of 82% combined with no decline in production during the initial two weeks cuts our operating costs significantly and meaningfully adds to our return on investment. This represents a notable milestone for Three Crown and validates our technical approach of soaking the well for 45 days after fracking, which increases the oil cut significantly." said H. Howard Cooper, President and Manager of Three Crown Petroleum LLC. "We are actively seeking reliable partners to participate in our Niobrara and Mowry drilling program in the Powder River Basin for the remainder of 2025 and throughout 2026, including the Irvine 1NH well."

Upcoming Wells and Development Program

Following the Irvine 1NH completion, Three Crown plans to spud the Kringen 1NH and Wild Bill 1NH Niobrara wells in Converse County, WY in fourth quarter 2025. Each well is designed as a 2.5-mile lateral located east of Bill, Wyoming.

Three Crown currently holds eleven additional Niobrara and Mowry drilling permits across Johnson, Campbell, and Converse Counties.

Partnership Opportunities

The Company is actively seeking reliable partners to participate in its Niobrara and Mowry drilling program for the remainder of 2025 and throughout 2026. Investment opportunities include, but are not limited to, the Irvine 1NH well.
