South Heart Area (Bakken, ND, USA)

News

October 30, 2010: Officials considering "man-camp" for South Heart area.

Scroll down to see the original blog regarding the sudden "explosion" of interest in the South Heart area; the initial focus was on the number of Fidelity permits in the area. Since then, for me, the South Heart area has become a bigger story.

The Original Blog

This is really cool; this image was sent to me by someone who obviously enjoys following Fidelity (MDU) activity in the Bakken.

Fidelity recently announced six new permits in the area around South Heart, North Dakota.

Here's a look at where those Fidelity permits are located in relationship to other wells in the area:



If you click on the image, it will open up in a new window and you can enlarge it for easier viewing.

The grids (light blue outline placed by MDU graphics) are two miles north-south, and one mile wide.

The "X" marks the city of South Heart, North Dakota.

The "W" is a Whiting well, Kubas 11-13TFH, NWNW 13-140N, #18837, a wildcat, plugged or producing status as of September 30, 2010.

The "T" is a Tracker Resources well (now a Whiting operated well), Brueni 28-1H, NENW 28-140N-98W, permit 19562, in the Green River oil field, permit only, no action yet. (Nov 3, 2010: now on the confidential list.)

Interestingly enough, this is the area that was the subject of "Teegue's" last posting on his blog site, dated March 23, 2010, with regard to Whiting' s new wells near the town of Belfield.

The 2010  Fidelity permits in Stark County:
  • Kostelecky 31-6H, Lot 2 6-139N-97W, wildcat, #19264
  • Wock 14-11H, SWSW 11-40N-97W, wildcat, #19275
  • Oukrop 34-34H, SWSE 34-139-97W, wildcat, #19277
  • Kostelecky 11-5H, Lot 4 5-139N-97W, Heart River oil field, #19685
  • Wagner 11-4H, Lot 4 4-139N-98W, Zenith,  #19688
  • Kuchynski 24-12H, SESW 12-140N-97W, wildcat, #19698
The link above to the Kubas well takes you to a press release. About halfway down is this on the Kubas well:
The Kubas 11-13TFH, located approximately five miles northeast of the Froehlich well, was tested on September 13, 2010 flowing at a daily rate of 1,780 barrels of oil and 1,035 Mcf of gas, or 1,953 BOE per day from the Three Forks formation. The 24-hour test was gauged on a 46/64-inch choke with a flowing casing pressure of 520 psi. The Kubas well was fracture stimulated in a total of 29 stages, 21 stages using sliding sleeve technology and the remaining eight stages using the “plug and perf” method. Whiting operates the Kubas 11-13TFH, holding a working interest of 90% and a net revenue interest of 73%.
A couple of points:

1. This is at the southeastern boundary of the producing Bakken formation in the Williston Basin, but from this point onward, the TFS formation continues in a southwesterly, southerly, and southeasterly direction.

2. Based on this note, it looks like 30-stage fractures seem to be the optimum number of fractures right now, balancing cost vs initial production. This comment is not based on this single well, but on many, many wells that have been reported. Yes, there are some super-fracks with 40 stages, but I don't see many of those, suggesting expertise and capability of the rigs is about 30 stages right now.

    1. I think it's great. An image is worth a 1,000 words. Saved me a lot of writing to be able to post an image.

    2. Do you know what the yellow areas on the map mean?

    3. I assume the yellow acreage is the area Fidelity controls around South Heart.

      The map is on the same slide that talks about acquiring 40,000 net acres, so I assume this is the acreage Fidelity (MDU) acquired.

      It looks like Tracker might have a permit in the area, so I don't know if Fidelity acquired this acreage from Tracker or if Tracker still has some acreage in this immediate area.

      But generally, when one sees colored areas on a slide like this, it represents the acreage controlled by the company making the presentation, unless otherwise specified.

    4. Whiting frac on the Froelick was all 24 stg plug and perf. On the Kubas was 20 stages PIP and 4 plug and perf. It would seem to me they are testing the economics and production rates. Stay tuned for the results. This may set the parameters for the TF in this area.

    5. Thank you very much. I still remain very excited about the Bakken and the TFS. This does not get old for me. I think we still have a lot to learn, and I really take my hat off to the roughnecks doing the tough work (especially the North Dakota winter coming) and the geologists, drillers, and CEOs trying to sort out best technology and processes. It has to be exciting for them, also.

      I am convinced that they will eventually solve the horrendous decline rate, also.

      Thank you for this bit of information; more pieces of the puzzle.
