Abstract

The TexNet Earthquake Monitoring Network and its partner dense seismic networks are now providing detailed information on seismicity in Texas. Areas of active seismicity include the Delaware Basin, Midland Basin, Scurry Co, Texas Panhandle, Fort Worth Basin, East Texas Basin, and the Eagle Ford operating area. Each of these areas has unique geologic and operating histories that need to be considered when assessing seismicity at the local to regional scale - the earthquake habitat. What are the similarities and differences in the habitats of these areas? Each area has a unique stress state, fault architecture, fluid pressure regime, tectonic history, operational history, and earthquake sequence history. Some areas appear to have mainly induced seismicity, some have mainly naturally-caused events, and others have a mix. Comparing the geology of these areas to each other provides insight into the specific characteristics that may be important to understanding earthquake cause and to defining the scope of steps required to reduce the hazard where possible.

Bio

Dr. Peter Hennings is a Research Scientist at The University of Texas Bureau of Economic Geology where he is Principal Investigator in the Center for Integrated Seismicity Research and a Lecturer in the Department of Geological Sciences. Peter retired after 25 years in the petroleum industry where he worked as a research scientist (Mobil Oil and Phillips Petroleum) and technical manager (ConocoPhillips). Peter received his B.S. and M.S. degrees from Texas A&M University and his Ph.D. from The University of Texas. Peter’s technical specialties include structural geology, seismic structural analysis, reservoir geomechanics, induced seismicity, and geology of Texas and the Rocky Mountains. Peter is an AAPG Distinguished Lecturer, GSA Fellow, and a founder of the AAPG Petroleum Structure and Geomechanics Division.
