Marcellus Shale Play

Natural gas estimates of 500 trillion cubic feet make the Marcellus shale play in the Appalachian Basin one of the more promising unconventional resources in North America. Advances in horizontal drilling and hydraulic fracturing have made shale production possible, the key challenge now is to do so safely and cost effectively.

Program Objectives

ION’s multicomponent seismic approach helps operators better understand the spatial variability in rock properties and often production in the target zones of interest. ResSCAN programs provide high quality structural imaging for geohazard identification and avoidance. These programs also establish which seismic and geomechanical attributes predict key reservoir characteristics, such as rock properties and natural fracture insights. Using this information, operators can
  • Pinpoint sweet spots
  • Optimize drilling and completions decisions
  • Maximize production
