Original Post

A big "thank you" to a reader who alerted me to this.

This well was completed and tested in November, 2008:

• 17201, 956, CLR, Mittlestadt 1-20H, Chimney Butte, t11/08, cum 211K 12/13;

This is the production run during a few select months in 2012, after this well had been on-line for a couple of years:

BAKKEN	3-2012	31	1550	1405	525	1088	1088	0

Look at the spike in production in July, 2012. Most interesting, this well was not taken off-line at this time for reworking or re-fracking. Something else needs to explain the spike.

In July, 2012, this well, drilled 475 feet to the west of that well was completed/fracked, and tested:

• 21569, 723, CLR, Mittlestadt 2-20H, Chimney Butte, t7/12; cum 151K 12/13:

BAKKEN	1-2013	29	10080	10027	3334	6839	6504	335

BAKKEN	6-2012	5	1522	1348	0	913	0	913

My hunch is that there will be more and more examples of the "halo effect" of fracking, as some call it. The operators are very aware of this. The average individual will only become aware of this if he/she has interest in adjacent wells that come on-line at least a year apart. I generally won't go looking for examples, but will post them as I come across them or if readers send me examples.

By the way: note the variability in natural gas production/flaring.

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

On a completely different note, look at the production of the newer Mittlestadt wells in the same section:

• 23605, 854, CLR, Mittlestadt 3-17H, Chimney Butte, t8/13; cum 57K 12/13:

BAKKEN	8-2013	4	1920	1723	233	3708	0	3708

For CLR, these are very, very good wells.
