The Halo Effect -- Update In Long Creek -- December 5, 2016

For background to this story, see these posts:
I think those posts provide more than enough background precluding another long note.

A reader who follows this area closely wrote this morning to suggest comparing:
  • 20085(H1) to the TFH wells #26676 and #26677; and
  • 19981, and the TFH well 28885 and the H well 28886.
The reader's very pithy remark: all of these after fracking. #20085 is "like a new well."

Here's the production profile for #20085. Even without looking at the background at the linked posts above, one can probably guess when neighboring wells were fracked after looking at the production data. There could be other reasons for increased production after neighboring wells were fracked (they are addressed at the linked posts above) but build-up of pressure while wells were off-line seems a bit of a stretch due to the length of time production remained so high.

The production profile after 12/15 looks just like a first-time post-frack production profile.

From an earlier post: sundry forms (newest ones first) for #20085:

  • Return to production, 6/14/15
  • Request to commingle
  • November 12, 2014: re-worked; 
  • November 7, 2014 (est): Zavanna will install a gas lift; a high pressure gas line has been run to the wellhead to inject gas down the casing annulus. Gas will go from casing to tubing through the gas lift mandrels/valves and will sue gas as the driver for fluid lift. A pumping unit will no longer be required while on gas lift. 
  • May 7, 2014: currently SI for offset Zavanna Angus drilling operations until further notice.
  • January 27, 2014: LACT unit installation.
  • May, 2013: pumping unit installed 
*****************************

Likewise, #19981, a middle Bakken well and its production profile below. Neighboring TFH wells #28885 and #28886 are incredibly good wells and were fracked shortly before #19981, a middle Bakken well, shown below, had a huge jump in production, again, well after all that excessive pressure should have been exhausted.
