Follow-Up On That Incredible South Fork Dakota-3 Well: 130,000 Bbls in < 6 Months -- No Pump -- 17 Stages -- KOG Nearby -- The Bakken, North Dakota, USA

While updating the top stories of 2011, I was reminded of this story:
  • 18922, 472, Dakota-3 (WMB), Dakota-3 Skunk Creek 1-12H, (South Fork field), 19,354 bbls in first 14 days; s9/10; t6/11; cum 416K 9/14;
So, how is it doing now?

The company did not summarize the completion report but attached the entire "well completion summary."

As a rule I do not read these summaries, so I may have some of the details incorrect, but this is what I see:
  • Spud: 9/25/10
  • Date TD reached: 11/2/11
  • 17-stage frack
  • Date of 1st stage: 5/13/11
  • Date of 2nd stage: 6/9/11
  • Date of 17th (last) stage: 6/12/11
  • Looks like about 130,000 lbs sand (including ceramics)/stage: 2.2 million lbs (very rough est)
This is part of the geologic summary: "The Zenergy Operating Company's Precision 517 Dakota-3 Skunk Creek 1-12 is a wildcat well located ... The initial phase of the Skunk Creek 1-12H is a vertical section, and curve landing in the upper part of the Middle Bakken formation. It will be re-entered at a later date as a single lateral coplanar well targeting the Middle Bakken Silty Dolomitic Limestone / Sandstone formation. The Skunk Creek 1-12H spudded September 22nd, 2010, and reached a Total Depth of 19,228 feet Measured Depth, and 10,490 feet Total Vertical Depth on November 1st, 2010..."

Production data:
Test date: 6/15/11
IP: 472
Still flowing (no pump)
Date/Days/Runs:
  • 11/11; 30 days; 18,154 bbls
  • 10/11; 31 days; 16,741 bbls
  • 9/11; 28 days; 17,587 bbls
  • 8/11; 31 days; 29,410 bbls
  • 7/11; 29 days; 31,310 bbls
  • 6/11; 14 days; 19,354 bbls
Of interest, KOG has a rig on site just to the west of this well, less than a mile away:
  • 21065, 539, KOG, Skunk Creek 9-2-3-12HS/Skunk Creek 9-2-3-12H3, t3/12; cum 144K 8/14;
At the time of the original post, I noted:
In South Fork oil field (where the Dakota-3 well is), there are 12 permits; three are active and producing; all the rest are confidential. But note this: 8 of the 12 permits belong to KOG.
Cost of well, according to the "well completion summary":
  • AFE budgeted: $6,487,650.00
  • Actual: drilling, $3,610,264.00; completion (fracking), $3,685,033.65. Total: $7,295,297,65.

  1. Continental has a couple interesting eco pads next to each other in Oakdale field.

    The Carson Peak 2-35H has produced 171,204 BBLs in basically 7months. Its sister well the 3-35H has produced 157,114 during the same time.

    A mile to the west the Whitman 2-34H has produced 109,436 BBLS in 3 month and the most interesting well of the area is the 3-34H as the well is an uncompleted open hole lateral 2,000 feet long that has produced 32,021 barrels. The had to stop drilling this lateral due to well control issues. What did the drill into in this area?

  2. Another great example, thank you.

    Your example and hundreds of others explain why oilmen with 30 years of experience say that they have never seen anything like the Bakken.

    This is all occurring in a business-friendly, industry-friendly, politically-stable state without the terrorism and instability of much of the rest of the world. It's quite an incredible story.
