My professional career has focused on both carbonate and siliciclastic sequence stratigraphy and related depositional patterns, i.e., I love to correlate, imagine the past and use that information to explore for oil and gas. I also became interested in horizontal drilling in the early 1990s, so at Masera we researched which formations worldwide would be the best candidates for resource plays. As a result, Mike Horn, Sada Joshi and I taught multiple short courses for AAPG on predicting resource plays. Along with many good co-authors, I have produced over 30 years of technical presentations and publications for AAPG and other professional societies. In addition, I have written significant proprietary publications throughout the United States with Masera Corporation, many of which we are bringing forward for publication in scientific journals.
