Update On The "Recent" Lodgepole Well Drilled By Hess -- August 11, 2019

From the July, 2019, issue of Geo News, ND USGS publication.

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:

LODGEPOLE	10-2018	31	469	610	1387	684	684	0

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

Update on this well. 

I posted this back on August 17, 2014:

• 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

Pilot hole core (plans):

Middle Lodgepole

• 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

Bakken-Three Forks

• 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

Drilling

• spud rig: December 6, 2013
• drilling rig: May 13, 2014
• cease drilling: May 16, 2014 (3 days)

Completion: June 27, 2014

• 37 stages
• acid frack; no proppant 

Location:

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;

An interesting well in the area:

• 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

Note: in a long note like this, there will be factual and typographical errors. I have no formal training in oil and gas exploration and I may have missed important points and/or misinterpreted data. If this information is important to you, go to the source.
