Zavanna Gas Lift -- September 3, 2015

I was in a rush to do this -- going off to soccer; there will be factual and typographical errors in a long note like this. If this is important to you, go to the source. A huge "thank you" to a reader for alerting me to this well, another great example of ... well, you will see. 

First, as a reminder, look at this earlier post.

Now, on to this well:

• 24543, 1,086, Zavanna, Bear Cat 33-28 1H, Williston, t4/13; cum 259K 7/15; unfortunately with current slump in oil prices and restrictions on flaring, we do not know to what extent this well might be choked back at the present time; unfettered, one can only imagine what this well could produce.

First, the production profile:

So, let's see if the file report shows what was going in last summer / autumn / winter (2014).

The well was returned to production on/about February 16, 2015, when the work was completed: workover rig to place/set gas lift packer assembly.

Shortly before that, a request to commingle: #24543, #25553, and #25552. (I will look at those again later.)

From a sundry form dated on/about November 3, 2014:  "Zavanna will install a gas lift on the Bear Cat multi-well pad location. Estimated January, 2015. With gas lift, we no longer use sucker rods. The tubing has been run with a packer on bottom to prevent flow up the casing annulus and gas lift mandrels/valves at specific depths in the tubing. 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 use gas as the drive for fluid lift. A pumping unit will no longer be required  while on gas lift."

Prior to that, well taken off-line for fracking other wells in the area.
