The 9-month Halliburton Services and Columbia Natural Resources (CNR) study showed a number of ways for improving gas production from Devonian shale and other tight gas formations. This paper discusses these conclusions and the supporting evidence. In the West Virginia study well, the effects of perforation direction on fracture initiation were illustrated by breakdown pressure differences and fluid distribution. This was determined with a prototype directional gamma ray logging (DGRL) tool that measures azimuthal distribution of the tracer. The perforation (4,857-4,860 ft) aligned with the least principal stress broke down at 3,238 psi, while the perforations (4,850-4,853 ft) aligned perpendicular to the least principal stress broke down at 2,731 psi.
