Getting the Last Gasp: Deliquification of Challenging Gas Wells

A common characteristic of “challenging” unconventional gas<br>resources, namely low permeability sands, shale and coal bed<br>methane, is that the ultimate recovery is dependent on<br>economic removal of liquids accumulation, generally termed<br>“deliquification”. This resource is making up an everincreasing<br>part of the North American gas supply. Since there<br>is no one “perfect solution”, and the problem affects thousands<br>of wells, the opportunity involves not only technology<br>development but also knowledge management and building<br>resource capability.
