David Johnston earned a BSC in Earth Sciences from the Massachusetts Institute of Technology in 1973 and a Ph.D. in Geophysics in 1978, also from MIT. He joined Exxon Production Research Co. (later ExxonMobil Upstream Research) and held assignments in rock physics research, velocity analysis and interpretation, and seismic reservoir characterization and monitoring. He moved to ExxonMobil Exploration Co. in 2002 where he was responsible for the worldwide application of time-lapse seismic technology. Starting in 2008 Johnston provided technical and business stewardship of ExxonMobil’s global production geophysics activity, including 4D seismic. He retired from ExxonMobil in 2017 and formed Differential Seismic, LLC, a geophysics consultancy. David is an Honorary Professor at Heriot-Watt University.

John Wild is a former Production Geophysicist with a near three-decade career in field development, life extension and evaluation of secondary reservoirs with Britoil, Mobil and Exxon-Mobil, that strayed significantly into geomodelling and reservoir engineering. Through involvement in all stages including validation through drilling of several large Canadian, UKCS and Norwegian time-lapse surveys and involvement in a large portfolio of UKCS fields he came to appreciate how much reservoir information remains to be unlocked from these unique glimpses into how reservoirs respond to production.

Jorg Herwanger is a global technical authority on integration of geomechanics and time-lapse seismic data. By collaboration with the Edinburgh Time-Lapse Project he helps to shape the next generation of “Seismic Geomechanics” experts, and creates new insights into monitoring of geomechanical processes in the energy industry. He is the founder and Principal Geoscientist at MP-Geomechanics and a Visiting Professor at Heriot Watt University. For various aspects of his Seismic Geomechanics work, he was invited twice as a Distinguished Lecturer by EAGE and as the 5^th EAGE Education Tour (EET) Lecturer. For the EET lecture tour he wrote the eponymous book on “Seismic Geomechanics”.

Henning Hoeber has held various research positions with CGG since 1998 and is currently research manager for reservoir processing, based in London. He coordinates CGG’s development of processing and imaging technology for reservoir imaging and analysis. After earning degrees from Hamburg University and Edinburgh University, Hoeber became a research fellow at the John von Neumann Supercomputing Centre in Julich, Germany, where he continued his research on lattice gauge theory and quantum chromodynamics. He has contributed to various articles and short courses relating to time-lapse technology, signal processing, AVO, and seismic and GPR diffraction. A co-editor of Classics of Elastic Wave Theory, he also coauthored Compendium of Theoretical Physics. Hoeber is Associate Editor of Geophysical Prospecting and a member of EAGE and SEG. Henning is a visiting Professor at Heriot-Watt University’s Edinburgh Time-Lapse Project.

Jorge Landa has technical interests that include research and technical services in the areas of reservoir engineering aspects of 4D seismic, reservoir flow simulation, probabilistic history matching and forecasting, 4D seismic history matching, 4D seismic inversion, reservoir surveillance, well testing, optimization, geostatistics, geomechanics, and inverse problem theory. He has more than 40 years of experience in the oil industry. He worked for Chevron USA and Halliburton Company. He holds a US patent, was an SPE Distinguished Lecturer, has authored SPE and SEG technical papers, co-authored in an SPE Monograph, participated in the organization of SPE conferences and workshops, and joint research projects with academia and a USA National Laboratory. Jorge holds Ph.D. and M.S. degrees in Petroleum Engineering from Stanford University, USA, and an Electro-Mechanical Engineering degree from Universidad de Buenos Aires, Argentina.
