The Mysterious Disappearing Natural Gas In The Bakken -- June 7, 2021

Note: this was done quickly during a lot of distractions. There may be typographical and content errors. But the general theme holds true. 

In all the examples below, there are nine columns.

The last three columns have to do with natural gas over the given month.

The sum of the last two columns "should" equal column #7, MCF produced. If not, the question is where did that natural gas go that is produced but neither sold nor vented?

A reader who has been following this for awhile and has sent me observations before regarding this issue, sent me this note today regarding four wells that came off the confidential list today and over the weekend:

That WPX well #37830 produced, but did not sell or flare, 100,000 cubic feet of gas per day its first month online
The MRO well #37250 produced, but did not sell or flare, 66,000 cubic feet of gas per day its first several months online. 
In contrast, Oasis has no such unidentified 'spread' in their gas production/sold/flared categories. That is, those 3 numbers add up precisely.

Observations ... 
Some effective gas lift is being used and - importantly - it is being used right from the start of production.  (By MRO and WPX, at least, in these instances). 
The "dreaded decline" in Bakken wells is very apt to take on a much shallower profile as gas lift can be an exceptionally effective means of recovering oil.

While the initial costs can be higher in installing the needed hardware, longer term operating costs can be much cheaper as sand problems, gassy flow through and other issues that damage ESPs are avoided when using gas lift.

The question: what innovations are companies like WPX and MRO using to produce more efficient lift with natural gas?

And, of course, the next question, will we start to see this in other companies, like Oasis.

I wonder what CLR numbers show. Randomly, I will simply look at one recently reported CLR well.

36056, A, CLR, Gordon Federal 15-8H, Haystack Butte:

If I did the arithmetic correctly, CLR's numbers are similar to those of Oasis.
