Twelve wells, eight seams, 320 acres. Which seams to perf? Which seams to avoid? Guess and hope - or test and know.

An operator needed to decide how to complete their multizone wells in the Wall, Cook and Canyon seams - and their five stringers. Conventional wisdom said to complete the lowest zone, the Wall, to get the most gas. Basin-wide anecdotes held that the middle zone, the Cook, was the best target. Surprisingly, both the conventional wisdom and basin-wide anecdotes were incorrect. Reservoir testing found more gas and less water in the most shallow seam, the Canyon. In addition, gas content and critical desorption presure in these continuous seams varied by up to 30% across the 320 acres.

A 2,240 acre coalbed methane field located on Clear Creek in the Powder River basin had been dewatered sporadically by three different operators over more than five years.
