March 5, 2015: a fairly exhaustive update of the Hartman wells has been completed.

On an unrelated note I eagerly await completion information on the Hartman wells by CLR.

Completion reports were recently added to the well files but a note indicates testing equipment was down so no production information was available????

They do list the proppant weights, types, and volume of liquid used in the frac and the dates fraced. From late July to early September. I wonder how accurate the information is?

All 6 wells used about the same volume of fluid, 5 of 6 wells about 200,000 lbs of proppant with one TF3 about 1/2 that. Most wells about 1/3 of the proppant was ceramic except the TF1 well which was around 80% ceramic if my memory serves me correct.

I scanned all 6 files then posted from memory. For reference these wells are only a few miles from the Hawkinson wells sweet spot and are spaced twice as close and appears to have used significantly more frac effort.

Note: some wells CLR used a lot more proppant than historically typical for CLR (which they suggested they were going to do).

**********************************

You have hit on the same problem I have: just too much information flowing (pun intended) from the Bakken. I, too, am eagerly awaiting results on CLR, EOG, and other wells and noting the completion techniques. Whiting and NCS (coiled tube fracking) are going to be particularly interesting.

All this time, we seem to have been focused on "sand vs ceramic" and how much proppant to use. Perhaps Whiting and NCS have found the real secret if we want to see the bar reset at a significantly higher level: precise placement of fluid and proppant.

But I digress. Thank you for the reminder about the Hartman wells and the data that is starting to be released.

It looks like it's time to have a stand-alone post on the Hartman wells.

The CLR Hartman Wells in Chimney Butte Oil Field, Dunn County

The Hartman wells are a pilot density project which I refer to as a 660-test. See CLR's corporate presentation, September, 2014. If the wells are not updated below, check this post also.
