The Process Innovation Called "Fracking"



(p. B1) I have come to North Dakota to observe the fracking of the Irene Kovaloff 11-18H, a well on the southern edge of the Bakken Shale. It is one of one hundred wells that will be fracked in the U.S. on this particular day in October 2012, 10 in North Dakota alone.


. . .


(p. B2) The hydraulic heart of fracking is the liquid pumped into the well. Almost all of it is water: snowmelt from the upper Rockies. In the Bakken and elsewhere, companies transform the water into a viscous liquid designed to carry sand deep into the new fractures. As it heats up underground, the gel reverts to a watery state. This change allows the sand to drop out and remain in the fractures, holding them open like pillars in a coal mine. The water flows back out.


. . .


Water and guar make up about 99.1% of the liquid; the chemicals are the rest.


. . .


The next night, the 30th frack of the Irene Kovaloff is completed. It takes three hours longer than expected, but otherwise the well is a success. Soon came light, sweet Bakken crude mixed with the water. On its first full day, it produced 800 barrels of crude--a good, but not great, result. By early 2013, Marathon had pulled 20,000 barrels of crude from the well. Considering that the oil had been locked away until the frack, it was good enough.
