About MEQ Geo

MEQ Geo was founded in 2008, after seeing the need for an independent consulting firm specializing in microseismic applications. Julie Shemeta has been involved with earthquake seismology since the 1980’s and microseismic applications from its earliest commercial uses in the 1990’s.  Bob Langan has 30+ years of experience in research and consulting services in oil & gas, where he has had many opportunities to combine his science and engineering background.

 Julie Shemeta (MS Geophysics University of Utah, BS Geology, University of Washington) is the founder and president of MEQ Geo and brings a global perspective and broad commercial microseismic experience to the company. She has worked on both surface, buried array and borehole microseismic projects in unconventional oil and gas resources in North America, Australia, Argentina, Mexico, Columbia and India. Prior to MEQ Geo, Julie worked for a major service provider in borehole microseismic services, the geothermal industry and offshore US oil and gas exploration. Her career has focused on seismicity related oil and gas and geothermal energy development. Julie shares an inventor's patent on stacked receivers for microseismic monitoring.

BobLangan

Bob Langan (PhD Geological Sciences, MS Civil Engineering, MS Geological Sciences, BS Electrical Engineering, all Northwestern University) retired in 2013 from a 32-year career at Chevron in earth science research and consulting services. While in graduate school he consulted with Soil Testing Services (later called STS Geotechnical Services), conducting geotechnical site investigations and foundation design. For his MS in Civil Engineering, he worked under Prof. Chuck Dowding on the response of residential structures to blasting vibrations, work which contributed to new standards for preventing damage and is now very relevant to the topic of induced seismicity. Bob began his energy industry career in 1981 as part of the team at Gulf Research credited with inventing reflection tomography. After Gulf was purchased by Chevron in 1985, Bob “got closer to the well head” by working on Crosswell Seismic Profiles (XSP) and Vertical Seismic Profiles (VSP). Over the next 14 years he planned and executed field trials involving over 70 crosswell profiles and co-managed an industry first 4D VSP in the Lost Hills Oil Field. From 1993 to 1995 he was a Visiting Scholar and Consulting Associate Professor at Stanford University, where he collaborated with Professor Jerry Harris and his students on the development of crosswell imaging technology. After spending three years on a deepwater exploration team (’99-’02), he returned to research where he initiated new programs in both microseismic monitoring and shale gas geophysics, and he provided corporate advice on seismicity near salt domes and induced seismicity risks from waste disposal.  Most recently he has been involved in VSPs in mining applications.

Bob is a member of the SEG, EAGE, and AGU. He has been active in numerous roles in these socities, including the following:

  • Over 45 publications in refereed journals, conference proceedings, and invited contributions to books.
  • Invited Paper, Opening Lecture, Northwestern University Seminar Series on Shale Gas (2013): “A Short History of the Shale Gas Phenomenon”.
  • Invited Paper, 2013 Australian Society of Exploration Geophysicists and Petroleum Engineering Society of Australia Annual Meeting, Keynote Address, “A Brief History of the Shale Gas Phenomenon in North America”.
  • Outstanding Paper Citation from the Society of Exploration Geophysics for 1985 paper in Geophysics: "Tomographic Determination of Velocity and Depth in Lateral Varying Media".
  • Outstanding Paper Citation from Society of Exploration Geophysicists for 1995 presentation at International Meeting: “Crosswell Seismic Imaging in the Permian Basin, West Texas”.
  • Invited Paper, 1999 Society of Exploration Geophysicists International Meeting, Special Session: Recent Advances and the Road Ahead, “The instrumented oil field: Implications for borehole geophysics”.
