Ohio Utica Shale

Shale gas production and high decline rates

By Jim Mackinnon Published: September 3, 2013

Shale energy production decline rates get analyzed by Michael Lynch at

Lynch: "In the case of decline rates, the fear has been that offsetting the falling production in existing reserves would make it difficult to increase production to meet rising demand.  Some call this the ‘Red Queen’ issue, running faster and faster just to stay in place.

"Only a handful of reports have analyzed decline rates in detail, most notably the International Energy Agency’s 2008 World Energy Report, which showed a gradual rise in decline rates over the course of decades.  Why rising decline rates suddenly had a major impact in the last decade is left unexplained.

"But decline rates are only one variable determining production levels, the other being additional drilling.  Production is the result of the natural decline rate and offsetting investment, such as infill drilling, water or gas injection, and many other techniques."
