ABSTRACT
Helper field, located on the southwestern flank of the Uinta Basin in
central Utah, produces gas from multiple coal seams and interbedded sandstone within the
Upper Cretaceous Ferron Sandstone Member of the Mancos Shale. Subsurface mapping, along
with coal and sandstone petrophysical properties obtained from two exploratory wells
drilled in 1993, led to the drilling of a five well exploratory pilot program that
established gas sales in 1994. Drilling from 1995 through 2003 resulted in the completion
of 111 additional coalbed methane wells. In mid-2003, Helper field was producing 35
mmcfg/day and production was increasing as pressure draw down continued. Full field
development is anticipated at 125 wells.
