Abstract
Technology Focus “Geology drives technology,” and “the best solutions are multidisciplinary.” Understanding the best way to develop an unconventional reservoir requires an understanding of the rocks and a close interaction between the geosciences and engineering. Without this base understanding and creative tension, unlocking the full potential of any play will not be achieved. Some of the greatest results in my career have come when working in a cross-functional team where all members were sufficiently aware of the geology to then apply the most appropriate technology for extraction. Interaction was open, robust, and balanced, and amazing results were produced. The most successful field developments that are being proposed today in unconventional gas use this model. For example, horizontal wells with multistaged stimulation that use image logs to identify and target existing rock fabrics highlight the close working relationship between drilling, geology, stimulation, and geomechanics. “Geology drives technology,” and “the best solutions are multidisciplinary”—this has never been more true than when developing and appraising on the challenging unconventional frontier.
