“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

Simon Chipperfield, SPE, is team leader of central gas exploitation at Santos. During the past 15 years, he has held positions in petroleum engineering (drilling, completions, and stimulation) and reservoir engineering. Chipperfield previously worked for Shell International E&P. He was awarded the 2007 SPE Cedric K. Ferguson Medal. Chipperfield has authored more than 20 technical publications in the areas of hydraulic fracturing, reservoir engineering, completion technology, and sand control. He holds a petroleum engineering degree with honors from the University of New South Wales. Chipperfield serves on the JPT Editorial Committee and the SPE International Awards Committee and has served as a reviewer for the SPE Production & Operations journal.
