Well, This Snuck Up On Me -- A String Of Legacy Wells Running North - South in Bottineau County -- Rig on Site -- The Spearfish, North Dakota, USA

For those interested in tracking Bakken/Spearfish wells just north of the Canadian border, consider this interactive map:

May 27, 2015: Legacy Oil + Gas acquired by Crescent Point.

June 25, 2014: Legacy buys Corinthian. See also this post

May 25, 2013: corporate presentation.

March 16, 2013: 
For quite some time I was confused by Corinthian, Legacy, and Surge -- three Canadian operators who extended their Canadian Spearfish play into northwestern North Dakota, most notably Bottineau County.

Surge bought Corinthian, but obviously a lot of older wells will still be "Corinthian" wells.

Legacy is separate from Surge, but both have close working relationships, at least in North Dakota.

According to Legacy's corporate presentation, February, 2013, in Bottineau County, ND:
  • the first 2 hz wells of the most recent program came on line; 150 boepd/well
  • 230 net locations; approx 97% unbooked
  • potentially more than 570 net locations @ 8 wells/section
  • 54K net undeveloped acres 
North Souris / Red Rock Oil Fields

These two fields are about 60 miles northeast of Minot; about ten (10) miles northwest of Bottineau. The North Souris runs east-west along the Canadian border; the Red Rock is south of the North Souris. North Souris has about 18 sections, including quarter/half sections along the Canadian border. Red Rock is 13 sections. These fields are pretty much "owned" by a Canadian company, Legacy, and targets the Spearfish formation. [This paragraph added September 17, 2012.]


April 4, 2013: Legacy announces acquisition of producing acreage in Canada. The deal: 32,522 net acres (some producing); operating netback of $60/boe); current production, 1,775 boe (90% light crude oil); $108 million cash and about 13.9 million x $5.48/share = $5,700/net acre, some producing.

February 13, 2013: operational update.

January 8, 2013: update on Legacy ops in the Williston Basin - a PDF file.

December 31, 2012: SeekingAlpha update of Legacy.

May 14, 2012: Legacy earnings and realignment with Bowood

April 2, 2012: Legacy Oil & Gas provides an operational update. If that link broken, try this one.

January 27, 2012: 2012 capex.  Looking for 30 percent production growth. Anticipating 16,300 boepd.
Legacy Oil and Gas and Corinthian (Surge)

Just east of the North Souris oil field is a string of wells/permitted locations running north to south (SF=Spearfish). Since the original post, more wells have been added.

  1. Nice article on UNDs work on increasing the recover of oil in the Bakken.

  2. Great link; great catch.

    I have been very, very impressed with what UND is doing.

    I think UND's involvement with the oil and gas industry has been under-reported in the mainstream media (as well as its aviation department).

  3. Legacy is drilling (almost) one mile laterals. Surge will drill half milesterals like EOG, in Q1. Both say the wells are good. Both also have wells in Canada.

    Legacy has two wells with problems that need rework or redrills.

    If all goes well, each may have one or two rig programs in a year or two.

    Surge mention Madison and basal Spearfish as well as Spearfish.

    Waterflood to come.

  4. Thank you. I don't have a good feeling for the Spearfish wells yet, but it's my understanding that the Spearfish is driving some of the oil activity (housing, oil services, etc) in Minot.

    That's interesting about the Madison. I still think we will see a resurgence in the Madison before this is all over.

  5. Any more insight on these wells??
    Seems to be more activity happening in the souris area with corithian and ballytine and legacy all active. I'm assuming Surge to follow soon...

    1. Someone else might have to help tonight -- I have a poor wi-fi connection and can't even access any basic information. My hunch is that not a lot has changed since I posted the above (at least publicly reported).

      I checked to see if any IPs for these wells had been reported, and none had.

      I will flag for later follow-up.

      Thank you for taking time to comment; sorry I couldn't be of more help tonight. Maybe someone else will respond.

  6. As a rookie, I'm not sure what all this means. But, it sounds good!

    1. Thank you. You are correct; it does sound like good news. I will post/link the site above. Thank for sending it might way; I would have missed it.
