Any Additional Information On CLR's Lawrence Wells?


Four Lawrence wells from the north, going south, paralleling the Lawrence wells noted in the original post:
  • 19534, 579, CLR, Lawrence 2-13H, North Tioga, t10/11; cum 401K 1/19;
  • 19536, 986, CLR, Lawrence 3-13H, North Tioga, t10/11; cum 364K 1/19;
  • 21518, 710, CLR, Lawrence 5-13H, North Tioga, t1/13; cum 207K 1/19;
  • 21516, 762, CLR, Lawrence 4-13H, North Tioga, t1/13; cum 196K 1/19;
August 2, 2018: production data has been update. Need to be re-fracked, it appears.

March 14, 2015: test dates, IPs, and total production to date has been updated in original post below. 

October 26, 2014: it looks like the Lawrence wells are coming back on-line. 

Original Post
A reader over at the discussion group had a question re:
  • 17745, 616, Lawrence 1-24H, CLR, North Tioga, long lateral, going due north through sections 24 and 13 (sited in section 24), cased hole frack; 1.4 million lbs sand; t2/09; cum 306K 6/18;
The reader noted:
On the Lawrence 1-24 (17745) well, the horse head has been removed, and flow lines capped with pressure gauges. I'm assuming its because they are soon going to be fracking the 6-well pad (Lawrence 6-11) to the SW as opposed to shutting the well in permanently.
And when fracking occurs will they also temporarily shut the Lawrence 2-5 in that on the same 1280?
What is the time span on fracking 6 wells on the same pad? 
I'll let others weigh in with more expert advice but my non-expert thoughts and comments:

It looks like the 6 wells referenced by the reader come off the confidential list between late May and early June, 2014, running west to east, updated October 3, 2014:
  • 26873, 235, CLR, Lawrence 7-24H2, North Tioga, t8/14; cum 75K 1/19; sporadic production; only 13 days of production 1/15; lousy well; needs to be re-fracked;
  • 26874, 1,130, CLR, Lawrence 11-24H1, North Tioga, t10/14; cum 122K 1/19;
  • 26875, 260, CLR, Lawrence 10-24H2, North Tioga, t10/14; cum 76K 1/19; off line as of 12/18;
  • 26876, 292, CLR, Lawrence 9-24H, North Tioga, t9/14; cum 132K 1/19;
  • 26877, IA/204, CLR, Lawrence 8-24H3, North Tioga, t10/14; cum 44K 6/18;
  • 26880, 343, CLR, Lawrence 6-24H1, North Tioga, Three Forks, 33 stages, 6.2 million lbs sand, t8/14; cum 76K 1/19;
Yes, according to the well file, #17745, was converted from "flow" to "pump" on October 28, 2013. It was a cased hole frack, 1.4 million lbs sand, February 4, 2009.

My hunch is that once they start fracking, they will have all six wells fracked in one month. So, maybe they start fracking soon (in some areas road restrictions have slowed things down, including Williams County in which these wells are sited); so I will guess we could see a test date in the June time-frame. Operators go to DRL status after wells come off CONF status if the wells are not fracked/completed, and have 30 days from the end of the month in which the well was fracked to report the results. So, if they frack/test any time in June, they have until August 1, 2014, to provide results.

So, we'll see how far off I am by the end of the summer.

If any experts want to weigh in, I'm sure the reader would be very appreciative.

Now, back to the original Lawrence well (#17745) above: this was a Three Forks well. The roughnecks reached total depth in 35 days. "Gas counts ranged from 800 - 2,000 units for approximately 2,500 feet MD, then began to decrease to 150 - 600 units....while in the target zone, gas readings were constantly near 2,000 units on average after, 12,000 feet. While out of target, gases ranged from 200 units to 3,000 units in the lower portion of the target. Trip gases encounterdd ranged between 5,000 - 10,000 units."


  1. This is probably the best reply ive ever gotten from the Bakken Shale Discussion group. Very informative. Although, im still not 100% on what is going on with #17745. Any other information on this well is very appreciated. Thank you much for the quick response and plethora of info :) G'Day!

    1. Thank you. Yes, we probably won't know what is going on with the original Lawrence well for a few weeks; at the NDIC site, through March, 2014, the most recent month data is available, shows that the well is still producing a full 30 - 31 days/month, about 2,000 bbls/month.
