Marcellus Utica: Faults, Fractures and Folds
What you will learn
- How to describe faults and fractures in carbonates, black shales, and coarser clastics as they occur in the northern Appalachian Basin.
This course will examine the characteristics of faults and fractures that affect the sedimentary units (including black shales such as the Marcellus) in the northern Appalachian Basin of New York State; we will also look into the tectonics that led to the formation of the structures in the northern Appalachian Basin and the adjacent Appalachian Orogen. We will finally study the slides from field trips that demonstrate faults and fractures in carbonates, black shale, and coarser clastics.
Robert Jacobi (PhD, Columbia, 1980) has taught for 34 years at the Universit at Buffalo, NY, where he is a Full Professor (currently part time). He is also a Senior Geology Advisor at EQT (Pittsburgh, PA). Prior to EQT, he was Director of Special Projects at Norse Energy Corp. USA, and a consultant for more than 20 years to business associates in oil and gas, mining, seismic hazards and other environmental concerns. He has worked for 40 years in the northern Appalachian Orogen and Basin. Dr. Jacobi’s present research integrates several sub-disciplines (including tectonics, structure, seismic, sedimentology, stratigraphy, aeromag, gravity, remote sensing, among others) in order to identify, understand, and predict faults, fractures, and folds, and their effects in the black shales for well production optimization, gas migration and fracking issues, and potential CO2 sequestration. He has worked in the Utica since 1980 and in the Upper Devonian black shales since 1989. He has authored or coauthored over 300 journal articles, book chapters, abstracts, and technical reports. Dr. Jacobi is past-President of the ES-AAPG, NE-GSA, ES-SEPM, and NYSGA. He is the recipient of several awards, including the “Outstanding Educator Award” by the ES-AAPG, for which the citation reads: “To an educator whose contribution transcends the classroom. He brings the world to his students and prepares them as a gift to the world.”
