Random Update Of BR #17118, A Re-Fracked Well -- July 6, 2015

A reader sent me this note as a comment to another post which I posted earlier, but I thought it would be interesting to take a look at this well. First the comment that the reader sent me:

Take a look at BR's #17118 just shows the potential of the untapped barrels by refracking old wells. It has produced more bbls in 9 months since the refrack than it did in the initial 6 years of production.

Now, to search the blog to see if I've talked about this well before:

• 17118, 289, BR, Remington 14-11H, Blue Buttes, t6/08; cum 211K 8/16; only 14 days in 8/16

Nope, it's only been mentioned once before, back on November 19, 2010.

Early production:

BAKKEN	6-2008	30	1260	968	702	596	596	0

Production after December, 2008, until June, 2014, was "pathetic." Then it was taken off-line for the entire month of July, 2014, and came back on line in September, 2014. Here is the production profile from August, 2014, to the present:

Pool	Date	Days	BBLS Oil	Runs	BBLS Water	MCF Prod	MCF Sold	Vent/Flare

So, what gives? What's the file report have to say?

From the most recent sundry form, recieved by the NDIC on April 24, 2014:

BR requests: to restimulate (re-frack) the lateral and increase production. The well was drilled and completed as an open hole well with a single stage completion. Precision 825 will be used to install a 4 1/2" liner and and the well restimulated (re-fracked). 

I assume "Precision 825" is a drilling rig.

BR does not currently use any of the following in fracking:

• fuels, diesel
• fuels, diesel, no. 2
• fuel oil no. 2
• fuel oil no. 4
• kerosene

There is an interesting letter on file with regard to royalties to a mineral owner. Mineral owners may be interested in reading the letter. The part that interested me:

If this was back-payments for production sold from the two wells, your interest may not be great enough to exceed the requirement in the paragraph aboeve (greater than $50). Oil prices in May 2007 were around $60/barrel and rose to over $140/barrel in July 2008. Unfortunately, prices dropped drastically to a low of around $20/barrel in December 2008 and this is reducing your payments significantly from what they were last year.

Original drilling / geologist's summary:

• target: "Sanish" member of the Bakken formation
• 20,831 feet
• gas units in the 5-- to 1,000 unit range; 5 - 8' flare

Completion:

• open-hole frack; perforated intervals, 11,193 to 20,382 feet
• 1,044,000 lbs sand
• 8,699 bbl gelled cross-linked fluid
• IP: 289

Think of all the open-hole fracks that operators might be interested in re-fracking. I may have missed it, but I did not see the amount of proppant used or the number of stages for this re-frack.

The original application said the target zone was the "Bakken," not otherwise specified. 

In a long note like this, there will be factual and typographical errors. If this information is important to you go to the source.

Look at the graphic: of the nine wells, one was recently re-fracked, greatly increasing production; the other 8 are waiting to be completed. And this is just one section in the entire Bakken.

There's one more data point about this well that is of interest, but I am purposely not posting it. I am posting this teaser in case someone else points it out, and I can say that I noted it also (for bragging purposes).
