Another Random Example Of Fracking Effects On An Existing Neighboring Well; The "Halo Effect" Of Fracking

September 8, 2014: possibly another example of the halo effect, #18362
 
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:

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:

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:

For CLR, these are very, very good wells.
