What have we learned?
- TI-WAO-157-95-14H-1 (TI-WAO)
- drilled in 2013
- initially completed in 2014
- sustained and continued production did not begin until mid-2015
- other vertical Lodgepole wells in northwestern ND, file numbers; PA = permanently abandoned; last date the well produced; A = active (producing)
- 6789: PA, 1980
- 7834: PA, late 1990s; Lodgepole: considered DRY
- 8645: PA, 1982; considered DRY
- 7820: A, West Tioga oil field; H. Borstad 34-1; a Madison well with test of Lodgepole (PNA); t11/181; cum 251K 6/19 (Madison, not Lodgepole)
- 26738 (TI-WAO); A
- formation: between ~ 9,300 feet (top) and 11,000 feet (bottom) vertical depth
- at the TI-WAO, between 9,000 feet and 9,600 feet, with well bore at 9,200 feet
- TI-WAO
- spud: December 6, 2013
- total depth: May 16, 2014
- TD: 13,625 feet which included a 4,400 foot lateral, middle of the Lodgepole Formation, approximately 400 feet above the upper Bakken (note the thickness of this formation)
- Lodgepole sits above the Bakken; Scallion is part of the Lodgepole, last major formation before the Bakken top
- origins of Lodgepole oil? possibly a combination of Bakken shales and inter-formational petroleum source beds
- TOC? in southern Saskatchewan, Lodgepole carbonate beds with TOC values of 4 - 8 wt%, which classifies as excellent quality petroleum source rock (the Bakken is as high as 11%, maybe greater; Saudi Arabia 2 - 5%)
- 4,400-ft lateral; about half the length of the typical 10,000-foot laterals used in the Bakken
- no proppant; 37 stages; 14,782 bbls of fluid (620,844 gallons)
- produced at a rate of over 100 bbls/day (extrapolates to 6,000 bbls/month had it been a long lateral)
- API: 44.5 API gravity
- first 24 hours: 103 bbls of oil; 143 bbls of water
- porosity: only 1 - 2% but increased to 4 - 6% near the TI-WAO target horizon
- permeability: all less than/equal to 1 millidarcy, similar to the Bakken-Three Forks
- recent production:

If the TOC truly is as high as 8%, this formation has huge potential, but porosity is a huge problem -- solution? hydraulic fracturing.

- 26738, IA, Hess, TI-Wao-157-95-14H-1, Tioga, this is a Lodgepole well; Hess will come back to this well on/about May 7, 2014, to drill this well to TD of 13,693 feet; and then complete it with a multi-stage acid frack; the company will core the upper and the middle Lodgepole; the company will also core the upper, middle, and lower Bakken; the company will core the 1st and 2nd benches of the Three Forks, and the upper 30' of the Three Forks third bench; 640-acre spacing for a Lodgepole well. [Updates: 12/14: no production since early September, 2014; Update: actually produced 60 bbls in one day in April, 2015; also noted that well is now IA (previously TA)]

Note the well is now active.
There were no new sundry forms after the August, 2014 update. The well was put on a pump o/a August 15, 2014.
The original geologist's summary back when the well was first drilled (the following includes direct quotes and paraphrasing, but mostly direct quotes):
- this is an experimental well testing the production potential of the Middle Lodgepole
- thirty-foot lagged samples were caught from 9,568 feet through the end of the lateral section at 13,625 feet [short lateral] in the Middle Lodgepole formation
- true vertical depth of the target formation: 9,219 feet
- after the pumps were started gas would peak at 9,568 units (sic) before the gas buster came into use
- "it should also be noted that the command center faced away from the flare stack and rig"
"Neset personnel would intermittently leave the command center to look for a flare but none was observed" - saltwater based drilling fluid was used throughout the lateral
- the target window would be ten feet
- the Lodgepole is a massive body of limestone in the Madison group
Middle LodgepoleDrilling
Bakken-Three Forks
- 9110' TVD - 9290' TVD for a total of 180 feet of core
- this core will include 30 feet above the middle Lodgepole, middle Lodgepole, and 30 feet below the middle Lodgepole; all of this core is in the Lodgepole
- 9550' TVD - 9780' TVD for a total of 230 feet of core
- 20' above the Upper Bakken Shale, Upper Bakken, Middle Bakken, Lower Bakken, Three Forks 1st Bench, Three Forks 2nd Bench, and 30' of the Three Forks 3rd Bench
- the rat hole for the open hole logs will end up in the Birdbear formation
- spud rig: December 6, 2013
- drilling rig: May 13, 2014
- cease drilling: May 16, 2014 (3 days)
- 37 stages
- acid frack; no proppant
The only other active well in the immediate area:
- 8257, 176, McRae & Henry, Ltd, Gallagher 43-15, vertical Madison well, t7/81; cum 160K 5/15;
- 12790, 242/115, Hess, Pederson 14-33, Silurian/Ordovician, the Silurian was drilled in 1991; before it was abandoned at the end of 2008, cum 814K bbls of oil; 1.4 bcf gas
