Random Update Of A Re-Fracked Older MRO Well In The Sanish Oil Field -- March 12, 2018; Another Wrinkle In The Bakken

MRO appears to continue it's aggressive re-fracking program.

Back on January 17, 2018, this DUC (#33290) was reported as completed:
  • 33290, 4,204, MRO, Lena USA 14-22H, Antelope, Sanish pool, t12/17; cum -- (#19144)
At the time I noted #19144 was in the immediate area and was curious what its production profile would look like once it was brought back on line. The well:
  • 19144, 952, MRO, TAT USA 34-22H, Antelope, Sanish pool, API - 33-053-03182, t3/11; cum 364K 1/18;
Here is the production profile:

A production jump like that suggests that the well was re-fracked, and checking FracFocus, it turns out that yes, indeed, it was re-fracked in November, 2018.

I assume other operators are doing the same but I haven't found any consistent examples. But it seems to be a "regular occurrence" that when MRO is fracking "new" wells, MRO often re-fracks older wells in the immediate area at the same time.

But look at this. Look how little water and proppant was used to re-frack this well:
  • water : 90.6% of total proppant by weight
  • water: 1,759,603 gallons
  • sand: 8.9% by weight
  • a gallon of water weighs 8.345404 million pounds
  • 1.76 million gallons of water weighs 14.7 million pounds
  • 90.6% of what = 16.2 million lbs
  • 16.2 million lbs total proppant (sand+water+all that other stuff)
  • 8.9% of 16.2 = 1.44 million lbs of sand 
  • my numbers may be off a bit but 1.44 million lbs of sand is an extremely small amount of sand to be using when fracking wells in 2018
  • it doesn't take a rocket scientist to see the point that is being made
  • if I have this correct, this is very, very clever -- what MRO is doing; just one more interesting wrinkle in the Bakken
