Technical Presentation: Felt seismicity in the vicinity of gas/oil production/gas storage facilities

When:  Jan 25, 2018 from 5:00 PM to 6:00 PM (CET)
Associated with  Vienna Basin Section

Seismicity in the vicinity of oil or gas reservoirs can be natural and induced. It is important to differentiate between the two types of seismicity not only from academic but also from economical point of view. This presentation will discuss theory and history of induced felt seismicity. Leo will show why seismic moment and total injected volume are related and explain why induced seismicity may occur in the vicinity of gas storage reservoirs or other producing fields. He will discuss two case studies: the Blackpool and Castor field case studies. Additionally, Leo will also discuss the Oklahoma seismicity and its relationship to salt water disposal. He will conclude with discussion on hazard assessment and mitigation strategies.

Leo Eisner started his professional carrier as a Senior Research Scientist with Cambridge Schlumberger Research where he filed five patents and issued numerous publications. He joined MicroSeismic, Inc. in 2008 and was promoted to chief Geophysicist in 2009. In the fall of 2010 he has accepted honorary position of Purkyne Fellow at the Academy of Sciences of the Czech Republic in Prague. He is founder and president of seismic service company Seimik s.r.o. He is a Continuous Education lecturer for SEG on microseismicity. His papers and extended abstracts cover a broad range of subjects, including the seismic ray method, finite-difference methods, seismological investigations of local and regional earthquakes and microearthquakes induced by hydraulic fracturing.
