The Bakken Never Ceases To Amaze Me -- An Update Of A Poorly Performing CLR Bakken Well -- January 21, 2018
Wow, I love the Bakken. The Bakken never ceases to amaze me. Earlier today I posted the wells that will be coming off the confidential list this next week and it was just like the old days -- a lot of new wells.Now, tonight, with nothing better to do, I was checking up on some wells that have always interested me. Among the thirty or forty or more wells I checked out I came across this one, a well that has already produced in excess of 1.5 million bbls of crude oil since 2011.

That's strange, I thought: taking a great well off-line with no explanation. So I went to the NDIC map to see what might be going on. Parallel to that horizontal, #20210, is its sister well:

Reading this file: "this well was drilled back in 2011. Drilling operations ceased on April 23, 2011, after dangerous levels of oil and gas pressure rendered further drilling unwise at the time. The well has been in production in its incomplete form (13,681' MD reached; open hole; no fracking_ since that time and has produced approximately 120,000 bbls of petroleum. This report primarily concerns re-entry drilling information only, as complete data from the original drilling was generated by a different mud-logging company and is at points incomplete." It was a difficult well to re-enter and complete, but "nevertheless, the well was drilled 100% in the delineated target." The target was the first bench of the Three Forks, "approximately 15' thick, beginning 15' below the Three Forks top, and extending to 30' below the same reference point." Re-entry date, July 5, 2017; TD date, July 8, 2017.
First frack, 9/22/17: 61 stages; 14.5 million lbs; with an IP of 1,008.
I've always wondered why this was such a poor well; now I know. Now, we'll see how well it does.
By the way, 120,000 bbls of oil without being fracked is not a bad well -- had it been a Madison well. But drilling a Bakken well back in 2011 was incredibly expensive; in comparison, Madison wells not so much.
