In late 2015, Nighthawk Production (Nighthawk) entered into a joint venture drilling agreement (JVD) with Cascade Petroleum (Cascade). The Monarch JVD encompassed 23,619 acres in northeastern Lincoln County, Colorado, where Cascade conducted a 3-D seismic interpretation to identify roughly 60 possible locations pursuing Pennsylvanian and Mississippian formations. After permitting a dozen Paleozoic ventures, the firm drilled four contractual wildcats. Nighthawk recently released details regarding their first completion in the area.
The Monarch #10-15, nw-se 15-8s-55w, was drilled in October 2015 to a total depth of 8,640’. Nighthawk originally reported that shows of oil were encountered in the Atoka, Marmaton, and Cherokee formations. Now released from confidentiality status, reports provided by the state indicate Nighthawk completed the well in the Atoka, initially pumping 9 bopd and 22 bwpd from the interval at 7,930’–7,984’. Between October 2015 and April of 2016, the Monarch #10-15 produced 1.3 k bo, 313 mcfg, and 57 bw, and at last report was extracting 17 bopd.
The second well drilled in the Monarch JVD program is 6 miles northeast of the Monarch #10-15. The Kicking Horse #7-13, sw-ne 13-7s-55w, reached a total depth of 8,541’ in late October 2015. No tests were conducted or cores were cut before plugging orders were issued for the failure.
Roughly a mile north of the Monarch #10-15 is the third well drilled by Nighthawk in the Monarch JVD. The Happy Jack #7-10, sw-ne 10-8s-55w, achieved a total depth of 8,400’. The operator reported the test encountered shows of oil in the Marmaton and Cherokee formations but log evaluations did not warrant setting production casing, and the well was abandoned soon after drilling.
The fourth attempt made by Nighthawk is approximately 6 miles northeast of the Monarch #10-15. The Northstar #1-14, ne-ne 14-7s-55w, reached a total depth of 8,575’. The main target for the test was the Spergen, which reportedly was void of hydrocarbons. According to the operator, other formations were evaluated but none had shows warranting casing. No details have been released regarding what other rocks were evaluated. The nearest established production to Nighthawk’s Monarch #10-15 is almost 4 miles to the southwest at a quartet of wildcats drilled by Cascade. The discovery well for this as-yet-unnamed pool is the Gaede #A9S-55W-05-43, sw-se 5-9s-55w. Drilled in mid-2014, the venture was tested in the Pennsylvanian Cherokee between 7,767’ and 7,777’ and given a calculated initial flow rate of 351 bopd, 211 mcfgpd, and 22 bwpd. Through June 2015, the strike cumulated 56.6 k bo, 67.6 mmcfg, and 14.6 k bw.
Less than a quarter-mile south of the Gaede #A9S-55W-05-043 is Cascade’s Gaede #9S-55W-8-16, nw-ne 8-9s-55w, which was drilled in October 2014. The prospect swabbed the Cherokee between 7,639’ and 7,679’ and had a calculated 24-hour flow rate of 278 bopd and 223 bwpd. Through April of 2016, the wildcat recovered 26.5 k bo, 26.7 mmcfg, and 5.3 k bw.
Approximately 8 miles northeast of the Monarch #10-15 is more Paleozoic production at the Keystone #3-7, nw-ne 7-7s-54w. Completed by Nighthawk in early 2015, this well initially pumped 83 bopd, 20 mcfgpd, and 297 bwpd from the Spergen between 8,254’ and 8,298’. Nighthawk also perforated the Simpson interval at 8,358’–8,364’ but only water was recovered, and that interval was temporarily abandoned. Assigned to Broken Spear Field, the Keystone #3-7 cumulated 31.5 k bo, 9.1 mmcfg, and 106.4 k bw through April of 2016.
