A Peculiar Phenomenon Of The Bakken -- Take A Bakken Well Off-Lline For A Few Months And Watch Production Surge When Brought Back On Line -- September 29, 2017

Well #1 and well #2 are adjacent horizontals. Well #1 is a new well among many new wells from the same pads running south to north; well #2 is an older well that runs north to south; it was not re-fracked, but even so production has surged. 

Well #1 below was fracked 1/31/2017 - 2/6/2017 and the data is already at FracFocus.

Well #2 well has not been re-fracked based on data at FracFocus.

Production of well #1, recently fracked:

From the archives: at this post, if you scroll down, there was a very, very interesting study back in 2009 -- "Simultaneous Hydraulic Fracking Treatments In Adjacent Horizontal Wells."

Years ago, I posted the likelihood that operators would run horizontals in opposite directions once in-fill wells started to be drilled. I won't be able to find it, but if I run across it, I will post the link.
