When Gerald Schotman, Shell's chief technology officer, looks at the unconventional oil and gas business, he sees so many young technologies and "from the perspective a chief technology officer, that is such an opportunity." Shell's list of promising areas for research and development is broad, ranging from creating cheaper, more effective sensors for seismic testing to a new generation of specialized, automated drilling rigs. The goal is always "change that creates value." In natural gas the rewards can be broken down three ways: produce more gas per well now, bring down the costs per well, and reduce the footprint when doing so. The footprint can be defined in many ways: the size of the pads used for drilling multiple wells; the level of emissions; the water used; and the many ways exploration and production can touch the people and the environment, near and far.
