Methane levels from the hydraulic fracturing of shale gas were 9,000 times higher than previously reported.
Finally, the model of matrix porosity and the evolution of permeability tensor of Microfracture for hydraulic fracturing rock is established.
Jackson said the data should be made available now to independent researchers and to agencies investigating the hydraulic fracturing process.
Mr. Howarth included methane losses associated with flow-back and drill-out processes in hydraulic fracturing and other unconventional gas drilling techniques.
Thanks to new drilling technology, and in particular a controversial process called hydraulic fracturing or "fracking," the size of the proven reserves is growing.
By cannoning water, sand and chemicals at them, a process known as hydraulic fracturing, or “fracking”, the bubbles can be released.
The reason for this “quiet revolution”, as Tony Hayward, the boss of BP, recently described it, is a drilling technique known as “hydraulic fracturing.
The pore pressure also strongly influences the state of stress in a formation (by as much as 50%) and is therefore a critical piece of information for designing hydraulic fracturing treatments.
Shale traps gas more tightly than other rock. To extract it, the shale is blasted with huge volumes of fresh water at high pressure, a practice known as hydraulic fracturing, or "fracking".
