chief technology officer, commented, “Te integration of ARKeX gradiometry technology with Global’s 3D seismic data sets will enhance our Basin Insight offering and provide unrivalled understanding of the Marcellus Shale’s structural complexity at a regional scale. “Tis is the first time that this


combination of technologies has been applied in unconventional resource exploration at such a scale,” he added. Te survey will be flown using BlueQube


technology, which comprises high-resolution gravity gradiometry, gravity and magnetic data acquired simultaneously using the same airborne platform (Fig. 1). Te data will be used to generate a high resolution 3D structural model over the study area, and the structural model is then used as input into the FEA work. Following the calibration of the stress and


strain fields present in the geologic model, FEA is used to calculate zones where there is a
