Calgary-based Energy Exploration Technologies (NXT) said on Friday that it has acquired an interest in over 3,300 additional acres covering its Antelope Tail prospect in the Green River Basin of Wyoming, increasing its project area including its adjacent Poblano acreage block to a total of 25,000 acres.

Cooperating with its U.S. joint venture and operating partner, CamWest Exploration LLC, the companies said they are currently attempting to contract a drilling rig and expect to drill the first Antelope Tail exploratory well in the fourth quarter of 2001. NXT said it believes the Antelope Tail prospect — located on the Pinedale Anticline — is one of the most prospective undrilled structures in the Green River Basin.

Located on the southeastern portion of the Pinedale Anticline in Sublette County, WY, The Antelope Tail is located near a number of significant overpressured Lance-Mesaverde natural gas discoveries made over the past few years, including: BP at Antelope, Ultra Petroleum at Warbonnet and Questar Corp. at Mesa-Stewart Point. NXT said that wells in these fields have tested at daily gas rates of 10-22 MMcfe/d. Operators in the area have upped estimates on recoverable reserves on the Pinedale Anticline and the adjacent Jonah field to over 5 Tcfe.

NXT and CamWest said that seismic data available leads them to believe that the Antelope tail feature has “unrisked reserve potential” that could exceed 200 Bcf of natural gas. The prospect was developed as a result of the use of Stress Field Detection (SFD) data acquired over the past two years. NXT’s proprietary SFD is a low-cost, airborne system that can identify subsurface structures, faults and fractures with “considerable accuracy,” the company said.

The companies also reported that they have entered into an agreement with Mountain Petroleum Corp. to complete the currently standing Bull Draw 3-11 gas well located on the Poblano acreage block on a carried interest basis. The companies said completion of the well and production testing operations are expected to extend over several weeks.

NXT, a U.S. oil and gas exploration company, holds a 5.6-22.5% working interest with varying overriding royalty positions in the Poblano-Antelope Tail Lance-Mesaverde project area.
