Three Crown Petroleum LLC announced a sustained initial flow rate of 752 barrels of oil equivalent per day (boe/d) from the recently commissioned Irvine 1NH well in Johnson County, Wyoming. The well, drilled with a two-mile horizontal leg, shows a high oil cut of 82% and has demonstrated no decline in output since entering production on October 14.
2025–2026 drilling programme expansion
The company stated that this performance reinforces its technical strategy in the region, including its 45-day post-fracturing “soaking” approach. The Irvine 1NH well was drilled to a total depth of approximately 22,500 feet and targets the highly productive Niobrara formation. It was completed using 51 hydraulic fracturing stages, spaced 200 feet apart.
Three Crown now plans to expand its programme with two additional wells – Kringen 1NH and Wild Bill 1NH – located in Converse County. Both are designed with 2.5-mile laterals, with drilling expected to commence in the fourth quarter of 2025.
Eleven additional permits across three counties
In parallel, the company already holds eleven additional drilling permits across Johnson, Campbell, and Converse counties, all located within the Powder River Basin. This permit portfolio enables a gradual scale-up of activity across the region.
Three Crown Petroleum is also actively seeking partners to support the execution of its Niobrara and Mowry drilling programme. The company noted that these investment opportunities include the Irvine 1NH well and upcoming 2025–2026 drilling prospects.
“We are actively seeking reliable partners to participate in our programme,” said H. Howard Cooper, President of Three Crown Petroleum LLC. “The results from the Irvine 1NH well demonstrate the strength of our technical approach and the investment potential for co-participants.”
