I Must Be Doing The Math Wrong -- Fracking Sand Volume -- February 24, 2017

Later, 11:57 a.m. Central Time: see comments below. Maybe it's pounds of proppant per foot per stage, but even so, not sure. Doesn't matter in big scheme of things. Just idle chatter. Bottom line: CLR thinks the law of diminishing returns applies to how much sand one uses when fracking. Fifteen pounds/foot may get as good a financial return as three thousand pounds/foot.
 
Original Post
 
Back-of-the-envelope:
  • Bakken horizontals are about 10,000 feet long
  • 1 million lbs of sand = 1,000,000 / 10,000 = 100 lbs / foot
  • 10 million lbs of sand = 10,000,000 / 10,000 = 1,000 lbs / foot
  • 30 million lbs of sand = 30,000,000 / 10,000 = 3,000 lbs / foot
Is that correct?

Note this article at Investor's Business Daily:
Continental Resources (CLR) plans to use less sand than other exploration and production companies do, as demand for materials used in fracking takes off and potentially adds to cost pressures for shale companies.

Glen Brown, Continental's vice president of exploration, said during a conference call Thursday that the bellwether shale company is using 1,000-2,000 pounds of fracking sand per foot as it tests enhanced completion techniques in the Bakken formation.

He noted that Continental's optimum range is closer to 1,000-1,500 pounds in the company's part of the shale play, while other operators in the area are using more than 3,000 pounds.
I must have done the math "wrong."

Over at "high intensity fracks" -- these are the exceptions -- run through the list, see how many are using more than 10 million lbs/frack. I'm not seeing it (yet). So either I must have done the math wrong (which is probably the case) or I mis-read the linked article above.
