In collaboration with Tad Patzek, I have been studying the physics of hydrofracture. There are two main areas of research. In the first, the goal is to extract information about well properties from well production. Our main finding is that well production in almost every play follows a universal curve that we compute based upon basic physical properties. A description of the work is at http://bit.ly/1wczGRY and the scientific publication is at http://bit.ly/1BiucIu
In the second area of research, the goal is to learn how the physical process of hydrofracturing results in a branched network underground into which gas flows. With a better understanding of the physical process, it may be possible to improve the productivity of each well.
