Cirque Escalating Program in the Northern D-J Basin

Laramie County, Wyoming

Cirque Resources (Cirque) of Denver is continuing their aggressive hunt for horizontal Codell reserves in the northern D-J Basin. The firm has staked the Paraiso #30-1-1CH, ne-ne 30-15n-65w, roughly 10 miles northwest of Cheyenne, Wyo. Proposed to reach a total vertical depth of 8,789’, bottom-hole location for this attempt is planned for the se-se 30-15n-65w.

In an unexplored section nearly a mile northeast of their Paraiso #30-1-1CH, Cirque has also permitted the Paraiso #19-16-1CH, se-se 19-15n-65w. Estimated to reach a total vertical depth of 8,799’, this wildcat has a bottom hole proposed to land in the ne-ne 19-15n-65w.

There is established Niobrara production roughly a mile southeast of the Paraiso #30-1-1CH. Golden Buckeye Petroleum’s Child Ranch #30-1, se-se 30-15n-65w, was drilled in 1984 and tapped the Niobrara at a total depth of 9,400’. The well initially pumped 14 bopd and 8 mcfgpd from the Niobrara zone between 8,441’ and 8,703’. Assigned to Silo Field, this vertical well recovered 612 bo and 342 bw before being abandoned in May of 1986.

Silo Field is the largest Niobrara oil pool in southeastern Wyoming, with additional production coming from the Codell. Through November 2013, total cumulative production for this reservoir was 11.2 mmbo and 10.2 bcfg from both the Niobrara and Codell. From 1983 through November 2013, total vertical and horizontal Codell output for Silo Field was 164 k bo and 188.8 mmcfg.

Nearly a mile south of Cirque’s Paraiso #30-1-1CH is Noble Energy’s Child VO #30-73H, sw-sw 30-15n-65w. Designated as the discovery well for Atlas Field, this venture was drilled in August 2010 and tapped the Niobrara at a total vertical depth of 8,903’. Bottom-hole location reportedly terminated in the ne-ne 30-15n-65w. The well initially pumped 41.5 bopd, 167.6 mcfgpd, and 142.4 bwpd from the Niobrara between 9,061’ and 13,704’. The Child VO #30-73H recovered 300 bo and 4.6 k bw through October 2011, when it was shut-in. Cirque took over operation of this test in late 2012.

Through March 2013, Atlas Field itself yielded 3.4 k bo and 2.7 mmcfg from two wells that draw from the Niobrara. Both are currently shut-in.

Less than a quarter-mile south of their Paraiso #30-1-1CH, Cirque has surveyed in location for the Anse Coco #30-29-5-1C-H, sw-nw 30-15n-65w. Slated as a lateral Codell wildcat with a total measured depth of 8,763’, bottom-hole location for the prospect is estimated to land in the se-ne 29-15n-65w. No activity has been reported at the drill pad.

Nearly a mile southwest of the Paraiso #30-1-1CH, Cirque has also staked the Katama #25-14-1CH, se-sw 25-15n-66w, to a total vertical depth of 8,892’ and a bottom hole in the ne-nw 25-15n-65w. Proposed as a possible horizontal Codell test, this wellsite has seen no activity.

Roughly 1.5 miles northwest of Cirque’s Katama #25-14-1CH, Lone Star Land and Energy punched in the State #15-66-24-1H, se-sw 24-15n-66w. This lateral attempt tapped the Niobrara at a total vertical depth of 8,751’ and was abandoned shortly afterward with no tests or cores reported. Bottom-hole location for this failure terminated in the ne-nw 24-15n-66w.

Almost 2 miles northeast of the Paraiso #19-16-1CH is the nearest Codell producer to Cirque’s new stakings. The Warren #17-1CH, ne-ne 17-15n-65w, was drilled by Cirque in December of 2012 and initially flowed 767 bopd and 235 mcfgpd from the Codell interval at 9,140’–13,002’. Through November 2013, the Warren #17-1CH recovered 56.8 k bo, 31.7 mmcfg, and 29.7 k bw. This wildcat has a bottom-hole location in the nw-nw 17-15n-65w.
