Another Look At The Rolf Well In Brooklyn Oil Field -- March 2019

Updates

May 2, 2019: an update.

Original Post 

Let's go back and look at this earlier posting. Re-posting, from a reader:

I thought you might enjoy this example of the Bakken being awesome.

More Rolf wells were recently drilled and fracked which produced this result on an existing well. This month it it produced 23,432. The new Rolf and Springfield wells have been capped, perhaps awaiting the new gas plant being built on section 16 in Brooklyn Township.

• 20183, 282, CLR, Rolf 1-20H, 33-105-02100, Brooklyn, t6/11; cum 270K 1/19; recent production -- no evidence this well was re-fracked; the full production profile of this well is posted here.

I wonder if anyone really looked at how big a deal this really is.

This well was originally drilled/completed in mid-2011. By September, 2018, it had produced a total of 249,409 bbls of crude oil. Then in January, 2019, no re-frack, it produced 19,636 bbls.

The following month, February, the reader said it produced 23,432 bbls of crude oil.

The raw numbers are impressive, but the percentages are even more striking.

• January, 2019: 19636 / 249,409 = 7.87%
• January + February, 2019: 43,068 / 249,409 = 17.268%

In other words, in two months, this well -- not re-fracked -- produced almost 20% of the total this well had produced between mid-2011 and the end of 2018. This speaks volumes about:

• the decline rate
• what we don't know about the Bakken
• and, a whole bunch of other stuff
