Subject: Re: re-frack question
I’m Jerry Lobdill. I am a chemical engineer and physicist (retired). I have been studying the technology used in drilling and completing horizontal gas wells since 2005.
I am unable to find more than a very few wells in the Barnett Shale whose production histories are consistent with even one successful refrack job.
In the gosanangelo.com piece Mr. Nicot suggested that some companies are refracking after, say, five years (quote below)
Mr. Nicot, please tell me what companies are doing this and if possible give me the API number of a refracked well.
I also ask Mr. Davis and Dr. Ireland for the same information if CHK is one of the companies that does refracking every 5-7 years, as was stated several years ago.
Please respond to this request by July 7, 2011 or send me email saying when I may expect an answer.
Thank you very much.

Hello, I saw your name in an article http://m.gosanangelo.com/news/2011/jun/25/one-scarce-resource-for-another-water-151-and-of/
and was wondering if you knew of specific wells that have actually been successfully refracked?
My understanding is that every 5 to 7 years that horizontal wells need to be refracked in order to keep the 20 to 30 year promise of well production for natural gas.
In speaking with Charles E Davis, a Chesapeake employee last night, I thought he said that Chesapeake doesn’t plan on refracking their wells.
I heard that a well can be re-fracked up to ten times, but I never came across a well that has been refracked yet.
I also want to know about stacked wells (Carrizo has experience with this). Can stacked wells also be refracked? Are stacked wells more likely to have methane migration?
The water intensive fracking process is worsened by the alleged need to be refracked at a later date and with the drought conditions, I wonder just how profitable drillers can be if the price of water increases for everybody?
Thanks for at least answering my refrack question-if you have the well(s) name or lease number, that would be great.
