Penn State researchers say they’ve found a better, lower cost way to identify potential high yield areas for Marcellus Shale gas extraction. How? By using well production data taken from more than 5,600 existing wells, and only for wells with at least two years of production logs, the researchers created decline curves. They then extrapolated those curves to the entire PA Marcellus region and say they can predict, with a pretty high degree of accuracy, the amount of gas that would be extracted if a new well were drilled in a given location. How cool is that?!
