Appalachian Basin Producing More Gas than Ever

Posted May 25, 2016 12:00 AM by Engineering360 eNewsletter

Low-cost Appalachian shale gas production has enabled the oldest U.S. natural gas producing area to re-establish itself as a supply juggernaut. Significant improvements in horizontal drilling and multistage fracturing are increasing the ultimate recovery per completion from 3 to 7 Bcf. As a result, overall production in the region increased ten-fold over the past five years. The real challenge becomes finding new markets for the increased production. The American Oil and Gas Reporter speculates on new uses for all that gas.

Re: Appalachian Basin Producing More Gas than Ever

I worked most of the Appalachian Basin, from W. Va. to N.Y. and Ohio for 11 years as a well logger. Don't think I ever did an oil well - just gas wells. Most wells were in a sand formation, but I was amazed by W.Va. where, in the late 1970's, they vertically drilled and simple fracked wells in the Devonian shales. Basically they still were quasi-sand wells as they looked for higher porosity stringers in the shale, which were a bit sandy. They were very very slow but long lived producers. I can only imagine what they are doing now, with the horizontal drilling.

There is one of the Marcellus shale wells about 2 miles from my house. They built a complete compressor station with mercaptan injection just for that one well to allow injection into a Columbia Gas pipeline. The post fracking flaring took most of a week. One of those old wells I logged would have been depleted by then.

Almost makes me want to go back to well logging, but just almost. Too much work even for the great pay.
