Re-Fracking

One year ago, October 25, 2009, I posted my "three-legged stool" of energy in North Dakota. One of the legs included horizontal drilling, multi-stage fracture stimulation and re-fracking. (I should have added multi-well pads).

Since that post I had not heard much about re-fracking. Until today.

Over on the Bakken Shale Discussion Group board someone asked how the Hess refrac wells were doing, noting that the HA-Thompson-152-95-1720H-1 and the HA-Dahl-152-95-0607H-1 had been recently re-fracked.

Many numbers rounded for easier tracking; see original source for exact numbers.

HA-Thompson-152-95-1720H-1

• First 30 days: 9,000 bbls
• Second month: 4,700 bbls
• Twelfth month: 2,000 bbls
• Twenty-fourth month: 1,200 bbls
• Twenty-eighth month: Re-frac -- no production
• First month after re-frac: 11,000 bbls (24 days)
• Second month after re-frac: 9,000 bbls
• Third month after re-frac: 7,000 bbls

HA-Dahl-152-95-0607H-1

• First 30 days: 10,000 bbls
• Second month: 7,600 bbls
• Twelfth month: 2,700 bbls
• Twenty-fourth month: 1,700 bbls
• Thirty-second month: 1,600 bbls
• Thirty-third month: Re-frac -- no production
• First month after re-frac: 14,000 bbls (20 days)
