Major Projects

Bryan’s work focuses primarily on well performance analysis in unconventional reservoirs using analytical and numerical modeling, coupled with production diagnostic techniques. His research led to the development of analysis techniques to assist with the interpretation of poor-quality production data.

Bryan has a broad background in well performance analysis for nearly all of the major shale and tight gas systems across North America (Bakken, Eagle Ford, Haynesville, Marcellus, Wolfcamp). He works extensively with PHDWin and Citrine to develop reserves estimates based on development plans, decline-curve analysis, well performance diagnostics, and economics.
