Random Update Of Zavanna's Nelson Well With Huge Uptick In Production Following Gas Lift -- August 24, 2015

HUGE THANKS FOR A READER OVERSEAS WHO BROUGHT THIS WELL TO MY ATTENTION (Sweden/Denmark) 

THERE WILL BY FACTUAL AND TYPOGRAPHICAL ERRORS. If this information is important to you go to the source, either NDIC or Zavanna.

*********************************** 

Important: when you look at the production profile below, note that the well went from less than 2,500 bbls over 20 days to almost 11,000 bbls in only 17 days. Extrapolated to 30 days one gets a well that went from 3,750 bbls/month to almost 20,000 bbls/month. 

For those who follow the "decline curve" discussion, imagine what this does to the decline curve.

See also this post on the Zavanna Angus wells in Stockyard Creek / Long Creek, about ten miles east/southeast of Williston. 

The importance of this well: note the huge increase in production after the well came back on-line. Things to consider:
  • error in reporting (previously reported for another well by another operator) when production was commingled; in this case, the other two wells to be commingled have not been completed to the best of my knowledge (SI/NC) although the paperwork could be delayed from what is happening in the field
  • gas lift
  • halo effect of neighboring fracks

Note: the horizontal laterals may be mislabeled, but I don't think so. The GIS map server is a bit difficult to read with where the horizontals originate.

Sundry forms (newest ones first)
  • 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
