Carolina Olivares
Carolina joined CGG Robertson in 2018 as a Senior Geochemist & Petroleum Systems Analyst. Before CGG, she worked with several E&P operating companies.
She has extensive experience in the integration of geological, geochemical data and basin modeling methods for petroleum systems evaluation at the exploration, field appraisal and development scale. Her experience also covers geochemical characterisation of source rocks and fluids, reservoir geochemistry, oil-source correlation, and most recently geothermal exploration and CCS.
When not at her desk, Carolina loves running, yoga and walking her two energetic springer spaniel dogs.

Richard Jupp
Richard has worked in subsurface imaging since 1998. He is a Group Manager in the U.K. seismic processing center, working on numerous projects, across all types of seismic data types and environments.
Richard has extensive experience of seismic processing across land, marine and ocean-bottom seismic disciplines and has published work in the fields of velocity model building and ocean-bottom seismic.
When not working, Richard likes to walk with his dog in the West Sussex countryside and tries to relax while stopping his dog from chasing people on bicycles.

Claire Gill
Claire is a carbonate sedimentologist and the Regional Manager for Geology in the Middle East based in Abu Dhabi.
She specialises in diagenetic analysis and carbonate facies modeling and, since 2013, she has been working in multi-disciplinary teams in order to extract value from the integration of data at all scales.
When not working Claire enjoys playing netball and exploring the natural world through running and walking. She also volunteers her time to support animal welfare organizations and is currently involved with the care and rescue of street animals.

Dr. Gilles Lambaré
Gilles is Chief Scientist and Manager of the Massy Geoscience Research Teams. His areas of expertise include tomography, FWI and pre-stack migration, and he has contributed to numerous articles and lectures relating to seismic wave propagation, seismic imaging, tomography and full-waveform inversion.
From 2012 to 2019, Gilles has been an associate professor at the Institut de Physique du Globe de Paris.
When relaxing from geophysics, Gilles enjoys an adorable and growing family and devotes himself to his other passions for family horticulture and the breeding of galinaceae.

Dr. Heather Clegg
Heather joined CGG as a Geochemist in 1997 and is currently a Senior Petroleum Geochemist. She has extensive regional experience of the petroleum geochemistry of North Africa, South America and the Middle East, and has presented work at many conferences on the petroleum geology and hydrocarbon potential of these areas, as well understanding how best to view and report geochemical data
When not working, Heather likes to bake cakes, has organised and taught Norwegian hardanger embroidery, and is currently learning how to quilt.

Dr. Ross Haake
Ross started his Ph.D. in 2001, working with ocean-bottom seismic data. His work with seabed seismic data continued through two post-doctoral fellowships at the Geological Survey of Canada, and a lectureship at the University of London, where he taught petroleum geoscience.
Ross joined CGG in 2011, working in both the research and processing departments on 3D and 4D seismic processing projects. He has published work on signal processing, imaging and velocity model building for PP and PS data, with 3D and 4D applications.
He is happiest tinkering with module code and trying to solve intractable problems.

Dr. Jeremie Messud
Jeremie works in research and development for subsurface imaging, where he leads two research teams developing innovative technology in the realms of FWI and artificial intelligence/deep learning.
His research topics include reverse time migration, orthorhombic tomography and migration, Bayesian uncertainties for velocity model building and migrated structures, optimal transport based full-waveform inversion, and deep learning for seismic processing.
Away from seismic, Jeremie is a keen musician – playing and performing different styles from laid-back blues to all-out alternative rock.

Gregor Duval
Gregor has led the multi-client and new ventures geoscience support team for Europe, Africa and Asia Pacific since 2011. He is a multi-skilled petroleum geoscientist with experience covering hydrocarbon exploration in the North Sea and Atlantic Margin basins, the Mediterranean and Caspian Seas and the Banda Arc basins around Indonesia.
He is a member of the Industry Advisory Board of Royal Holloway University of London for their MSc in Energy Geoscience program.
When not at work, he keeps busy trying to be a good father for his little three-year-old daughter, and he enjoys competing in the local badminton leagues.

Ranald Kelly
Ranald Kelly recently joined CGG as Chief Petroleum System Analyst. His expertise focuses on implementing and improving petroleum system workflows, with integration into the wider exploration process.
Ranald’s career, working with many operators in a host of geological environments, has provided the opportunity to develop the ideas on the “integrated charge evaluation” workflow common in the industry today; hydrocarbon fluid geochemistry and bulk character, source rock characterization, and petroleum systems modelling are integrated into a single, self-supporting and testable geological concept.
At home, Ranald is a devoted father of three free-range children and is inspired by the idea of sustainable self-sufficiency.

Dr. Mark Cowgill
Since joining CGG as a structural geologist in 1995 Mark has held a wide range of technical and managerial posts. He is currently Technical Advisor to the Geology and Geophysics group.
Mark has extensive experience of the petroleum geology of North Africa, the Middle East, the UKCS and South Asia. He has presented work at many conferences on the petroleum geology, geological evolution and hydrocarbon potential of these and other petroleum-rich areas such as the Gulf of Mexico and the Caribbean.
When not working, Mark likes to cook, walk his dog and chop wood, but not necessarily all at the same time.

Keith Maynard
Keith joined CGG Robertson in 2019 and is the Technical Director of the Geoscience Interpretation Group. Prior to CGG, he specialized in geologically focused seismic interpretation with a number of E&P operating companies.
He has 40 years’ experience across the full E&P project lifecycle, including roles in new venture acquisitions, prospect evaluation and drilling, field appraisal, and production geoscience. His most recent roles have been in leading technical quality assurance processes.
When not working, Keith enjoys spending time with his family, painting, enjoying the outdoors by biking and hill walking, and working on his wildlife garden.
