Oklahoma-based Lowry Exploration (Lowry) appears to have a probable dry hole at a Pennsylvanian test recently drilled some 33 miles east of the city of Gillette and 22 miles west of the community of Sundance in Crook County, Wyoming. Spotting on the eastern flank of the Powder River Basin, the Tulsa independent has requested approval to temporary abandoned the Williams #2-13, se-nw 13-50n-67w. Set up as a 3,850’ straight-hole Minnelusa venture, Lowry has set cement plugs across the Minnelusa interval at 3,840’–3,632’, the Dakota/Lakota zone between 2,340’ and 2,066’, and a surface plug at 383’–483’.
Lowry has indicated they are re-evaluating their geology in the area and may consider a sidetrack hole to the Williams #2-13, indicating that some type of shows were encountered. The failure retains its tight-hole status, and no data has been released by the operator. The Williams #2-13 represents the second Pennsylvanian wildcat drilled by Lowry within this section and the third such exploratory test drilled by the firm in the immediate area. Almost a quarter-mile south of the Williams #2-13, Lowry completed another shallow Pennsylvanian test at the Williams #1-13, ne-sw 13-50n-67w, a Minnelusa effort that bottomed at a depth of 3,894’. Abandoned in October 2014, this prospect had no coring or tests performed; however, during drilling the Minnelusa was described as “wet.” Log tops of the Williams #1-13 include the Dakota at 2,202’, Sundance at 2,750’, Goose Egg at 3,452’, Opeche at 3,668’, and the Minnelusa was picked at 3,762’ beneath a ground elevation of 4,163’.
Lowry’s Williams #2-13 is surrounded on three sides by failures. Almost a quarter-mile to the northwest, Brower Oil and Gas drilled a Jurassic Sundance well at the Keyhole Federal #1-13, sw-nw 13-50n-67w. With no significant shows encountered and no production casing run, this 3,875’ attempt was abandoned some 15 years ago.
A similar distance southeast of Lowry’s recent staking, Inca Oil and Gas (Inca) drilled a Pennsylvanian failure at the McKean Fee #33-13, nw-se 13-50n-67w. This wildcat bottomed in the Minnelusa at a depth of 3,524’. Two DSTs were conducted in the Minnelusa interval at 3,415’–3,452’. The tests recovered water with no shows of hydrocarbons, and the wildcat was plugged in 1984. The Minnelusa top in the McKean Fee #33-13 came in at 3,382’ beneath a KB elevation of 4,140’.
Another Minnelusa failure spots a quarter-mile southwest of the Williams #2-13 indicated dry hole. Drilled by Adobe Resources (Adobe), the Wind Creek #W-83474 13-13, nw-sw 13-50n-67w, tapped the Minnelusa at 4,160’. Prior to abandoning this attempt in 1983, Adobe ran one DST in the Minnelusa from 3,980’ to 4,001’, where the pipe reversed out 2,381’ of water. No other fluids were recovered, and the duster was plugged. Log tops of the Wind Creek #W-83474 13-13 include the Spearfish at 3,158’, Goose Egg at 3,638’, Opeche at 3,936’, and the Minnelusa at 3,983’.
The only other well in this section is a dry hole drilled by Inca that spots more than a half-mile southwest of Lowry’s Williams #2-13 disappointment. The Federal #43-13, ne-se 13-50n-67w, bottomed in the Minnelusa at a depth of 3,660’ and was plugged in 1986 with no cores cut or tests conducted.
Lowry has been active in this immediate area in the past. Almost two years ago, the company drilled a Minnelusa well nearly a quarter-mile southwest of their current exploration. The Williams #1-24, nw-ne 24-50n-67w, was a vertical wildcat that bottomed in the Minnelusa at a depth of 3,608’. This attempt was abandoned in June 2013 with no cores taken or tests run. According to information in the well report, the Minnelusa interval between 3,630’ and 3,808’ appeared to be wet. The log top of the Minnelusa in this failure was picked at 3,630’ beneath a KB elevation of 4,159’. The closest Minnelusa production to Lowry’s Williams #2-13 is some 2 miles to the southwest at Robinson Ranch East Field. Discovered in 1961, this pool has cumulated more than 2 mmbo and currently produces from two active wells. Roughly 3 miles east of Lowry’s apparent dry hole is Keyhole Field. This small Lower Cretaceous (Fall River) reservoir has produced just 32 k bo following its discovery in 1967.
