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:

Pool	Date	Days	BBLS Oil	Runs	BBLS Water	MCF Prod	MCF Sold	Vent/Flare
SANISH	1-2018	22	17936	17796	14782	29794	9197	18607
SANISH	12-2017	8	8163	8540	0	10702	698	9119
SANISH	11-2017	2	1407	931	0	1111	0	948
SANISH	10-2017	0	0	0	0	0	0	0
SANISH	9-2017	0	0	0	0	0	0	0
SANISH	8-2017	0	0	0	0	0	0	0
SANISH	7-2017	3	120	225	51	194	8	136
SANISH	6-2017	30	2411	2485	536	2778	0	1941
SANISH	5-2017	31	2487	2510	520	2887	15	2014

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
