Ray Abma Author

Ray Abma graduated from Stanford University in 1995 with a Ph.D. in geophysics after working in the Stanford Exploration Project with Jon Claerbout as his advisor. He graduated from Iowa State University in 1974 with a B.S. in Physics and minors in Mathematics and Computer Science. He worked for BP and ARCO as a senior research geophysicist from 1997 to 2018, Shell from 1995 to 1997, and Western Geophysical from 1974 to 1991. He is presently a visiting scientist at the Texas Consortium for Computational Seismology (TCCS) at the University of Texas in Austin. Ray's research interests are noise attenuation, interpolation and regularization, simultaneous sourcing, and coded sources.

Mark Foster retired from BP in 2016 as Director of Technology Integration, Upstream, based in London. During his 26-year career in BP, he held various positions in seismic processing, acquisition, and operations based in numerous locations around the world from Australia and Indonesia to Colombia and Trinidad and Tobago. These roles varied from running geophysical operations and survey teams to hands on seismic processing and processing QC roles. He created and ran the Land Seismic R&D program in 2006 that resulted in the acceptance of land simultaneous source technology at BP. Prior to BP, he worked for Shell International in The Netherlands as a seismic geophysicist. Mark has a Ph.D. in Solid State Physics from the Cavendish Laboratories of Cambridge University, UK where he also obtained a B.A./M.A. in Natural Sciences (Physics).
