Name Change

Earlier (original post was March 14, 2010, updated in August), I reported on CLR's Eco-Pad in the Little Knife oil field:

Note the "Orion Belt" of  the four CLR wells in section 12 of T146N-97W, all four are confidential as of August 30, 2010, most likely all four are drilled:

18515 -- CLR, Hegler 1-13T, first of the four to be reported (August 30, 2010)
18513 -- CLR, Arthur 1-12T
18747 -- CLR, Hegler 2-13H, new permit, 23 Feb 10
18748 -- CLR, Arthur 2-12H, new permit, 23 Feb 10; rig was on site; now off

From east to west, the distance between the outside wells is 105 feet. From the nomenclature, one can see that two of these wells will be going south into section 13, and two wells will be going north into section 12. Two of the wells (Hegler 1-13T and Arthur 1-12T) will be targeting the TFS; the other two will be targeting the Middle Bakken. (It is interesting that the NDIC GIS map server does not use the "T" designation, but that is how the NDIC daily activity report reported it.

In addition, I have seen the designation of two of the wells as "M" wells (Hegler 2-13M and Arthur 2-12M) suggesting the Middle Bakken.

It now appears that all are known by the "H" designation, but historically this helps us keep track which formation is being targeted by which well. Some suggest that the reason that there was no data provided when the first of these four wells came off the confidential list was because all four wells were fracked at the same time, and that will delay reporting of how the wells are doing.
