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)

    this re frac process will increase when these drilling companies have more of there leased land held by production ( hbp ) . the companies want to get the initial well going and i project in about 3 years this willbe a bakken norm.

    You know, Don, after listening to the CLR earnings conference call (just a few minutes ago), it's obvious "we're" just beginning in the Bakken. It is incredible how much work there is yet to be done just to hold their leases. It's incredible. I sound like a broken record but that's why I'm not worried about these quarterly earnings reports yet; this is all seed corn that is being planted. We'll see staggering numbers of production two and three years down the road, and then re-frac and then EOR.
