Wichita, Kan.–based Grand Mesa Operating (Grand Mesa) is anticipating more Paleozoic work in the D-J Basin, roughly 25 miles north of Arriba, Colo. Pending approval from the state, the operator has staked the Big Jake #1-18, ne-sw 18-5s-53w, Washington County, to reach a total depth of 8,300’ with plans to evaluate the Pennsylvanian and Mississippian for oil.
Roughly a mile northeast of the Big Jake #1-18, Grand Mesa has two additional Paleozoic permits. The True Grit #1-8, se-sw 8-5s-53w, is planned to reach a total depth of 8,200’ and evaluate the Cretaceous, Pennsylvanian, Arbuckle, and Mississippian zones. Approximately a half-mile east of the True Grit #1-8 is the Hondo #1-7, se-se 7-5s-53w; geologic targets and total depth are the same as the former staking.
The nearest exploration to Grand Mesa’s new staking is less than a half-mile to the northwest at Gulf Oil’s Doughty #1, ne-nw 18-5s-53w. Drilled in 1962, this well tapped the Skull Creek at 4,655’. A single core, which was obtained in the J Sand between 4,605’ and 4,655’, was described as “rotten” shale that consisted of bentonite, shaley siltstone, and grey shale.
Almost a half-mile west of Grand Mesa’s pending Big Jake #1-18 staking, in 1969 Denver-based Arrowhead Exploration punched in the Daughty #1, ne-se 13-5s-54w. This attempt bottomed in the J Sand at 4,739’. No tests were conducted or cores taken before the well was abandoned later the same year. Less than a mile northeast of the proposed Big Jake #1-18 is Davis Oil’s Scrivner #1, nw-sw 17-5s-53w. Drilled in 1957, this prospect bottomed in the Lakota at 4,888’ and was abandoned with no tests run or cores cut.
Wiepking-Fullerton Energy also holds a Paleozoic permit in the area. Approximately 1.5 miles southwest of Grand Mesa’s anticipated Big Jake #1-18 is the Buzz’s Boat #14, se-sw 24-5s-54w, which was expected to reach a total depth of 8,400. No activity has been reported at the well site.
Roughly 4 miles southwest of the Big Jake #1-18 is the only test in Washington County that produces from a Paleozoic interval. Spud in September 2014 by Nighthawk Production (Nighthawk), the Salen #14-35, se-sw 35-5s-54w, reached a total measured depth of 8,321’ in the Precambrian Granite. Dually completed in the Marmaton at 7,228’–7,234’ and the Cherokee between 7,426’ and 7,429’, the well had an IPP of 407 bopd and 19 mcfgpd. Between October 2014 and January of 2016, the Salen #14-35 yielded 17.6 k bo, 3 mmcfg, and 96 k bw.
Nighthawk’s Salen #14-35 is the northernmost producer in Arikaree Creek Field, which was discovered by the operator in 2012. The pool opener, the Steamboat Hansen #8-10, se-ne 10-6s-54w, reached a total depth of 8,500’ and initially pumped 230 bopd, 50 mcfgpd, and 1 bwpd from the vertical Spergen between 8,027’ and 8,065’. Going on-line in November 2012, through September 2014 the Steamboat Hansen #8-10 had recovered 182.1 k bo and 14.3 mmcfg. This field opener is currently shut-in. Through January of 2016, Arikaree Creek Field had produced 1.5 mmbo and 244.3 mmcfg from 13 reporting wells.
