I love industry documentation because it always provides a rare opportunity to catch them telling the truth.
A presentation by: ADVANCED RESOURCES INTERNATIONAL, INC.
Prepared for: Gas Shale Development Workshop
U.S. Department of Energy
U.S. Trade and Development Agency
This presentation focused on the Barnett Shale, which it calls the “gold standard of shale gas development.”
On slide #6 they clear up one of the frequent lies industry and our regulators like to tell us: They have been hydraulic fracturing gas wells for 60 years. That’s only partially true.
Not only is horizontal shale drilling a new technology that was only started in 2002, through 2003, there were only 76 horizontal wells in the Barnett Shale. By 2006 there were 1008 horizontal wells. This technology is so new that it’s still in the experimental stage.
Slide #11 explains that for decades natural gas production depended on natural fractures and the wells were shallow, vertical wells using small fracks.
At first Mitchell Energy experimented with refracking the wells when the production decreased.
From slide #27:
Further analysis also showed that many of the early well failures in the lower Ro areas were due to lack of fracture containment rather than insufficient thermal maturity.
I wonder if “lack of fracture containment” had anything to do with the contamination of Jim Bartlett’s water well.
On slide #31 you can see how little they know about how far and where their frack jobs go.
Slide #35 shows the newest hydraulic fracturing technology, a 12 stage fracture that will use 18,000 barrels of water per stage.
18,000 bbl X 42 gallons/bbl = 756,000 gallons
756,000 gallons per stage X 12 stages = 9,072,000 gallons
Remember, this water is not at all like the water used to water golf courses which is a claim industry loves to make. They water they used is a permanent withdrawal of our overall water budget. Natural Gas Production Causing Water Bankruptcy
On slide #42, we learn that the optimal well spacing in order to “raise gas recovery to over 50%” is 20 acres/well. But on slide #44 they admit that 20 acre well spacing would diminish individual well performance.
Downspacing to 40- and 20-acre would increase the recovery of gas inplace to over 50%, although well performance would decline.
I think the important thing to consider in that quote is that the reserve gas figures they bandy about are only 50% recoverable at best.
UPDATE: Why do you suppose Tarrant County is trying to get water from Oklahoma? Maybe Tarrant County should call for a temporary moratorium on new drilling permits until drillers can recycle the water they are using.
