At 19,000 bbls in the first 4.5 months, this Spearfish well looks to be as good as a middle Bakken well.Disclaimer: I may be completely wrong on everything I said on this page. I often read things incorrectly. I often screw up simple arithmetic; don't even get me started on math.
The total vertical depth of this well was 3,015 feet (no typo). A typical Bakken well will go down 9,000 to 11,000 feet. The total depth was 5,900 feet, so the horizontal, including the kick-off point/curve was about 3,000 feet. The "standard" Bakken well will run a horizontal three times that long, 9,000 feet, or almost two miles.
It was fracked with 167,551 lbs of sand (no typo), 19 stages. Total water used was 1,660 bbls (about 70,000 gallons). A typical Bakken wells uses about 4 million gallons of water, and about 4 million lbs of sand (EOG is testing with 10 million lbs of sand. Again, look at the amount of sand (almost none, compared to a Bakken well; and the water, almost none). According to a very unreliable source: A water tanker truck, of the largest 18 wheeler kind, can carry about 30 tons of water. Which is about 8000 gallons. So, was this about 10 truckloads of water? A Bakken well in comparison would require 500 truckloads of water. [This was corrected; see first comment.]
But that's not all. What else did you notice about this Spearfish well compared to a typical middle Bakken well?Again, I may be completely wrong on everything I said on this page. I often read things incorrectly. I often screw up simple arithmetic; don't even get me started on math. Let me know if I'm seeing something wrong.
Bingo! Good for you. I saw that, too: minimal decline rate. Production did decline but not all that much on a percentage basis. My hunch is that it has probably already leveled out.
Oh, one more thing. How many days did they have to pay for the rig? It was spud November 26, 2012; the rig was released December 1, 2012. That's barely enough time to drive into Williston and back to get a McDonald's hamburger before the well was completed. Five, six days?
Awful close the bottom of the potable aquifer at 3000 feet depth.
ReplyDelete1 bbl = 42 gallons
ReplyDeleteThank you. I've made that mistake before. Much appreciated that you caught it. I will correct the post tomorrow when I have more time.
