Rob Hearst – Chief Geophysicist: P.Geo., B.Sc., M.Sc.
Robert has many years of project management experience in exploration geophysics. Having obtained his HB.Sc. (Geophysics with Geology specialization) from UWO in 1983, he commenced work with Paterson, Grant & Watson Ltd. (PGW) as a geophysical consultant. In 1993 he obtained an M.Sc. (Geology and Geophysics) from McMaster University. During the ensuing years, Robert has held many roles, technical and management, both as a consultant and as Chief Geophysicist at McPhar Airborne Survey, President and Chief Geophysicist at MPX Airborne Surveys, Manager Interpretation at Quantec Geoscience, Chief Geophysicist for Asperbras, and Chief Geophysicist for Areva Resources Canada Inc. He has worked on the ground in North America, West and Central Africa, the Middle East, China and India. He is a member of the PDAC, SEG, CSEG, ASEG, EAGE and KEGS (past President) and is a registered Professional Geophysicist with APGO, APEGS, APEGA and NAPEG.
Benoît Tournerie – Senior Geophysicist: P. Geo., Ph.D. in Earth Sciences – Geophysics; French distinction
Benoit provides analysis and interpretation of magnetotelluric (MT), DC and IP data for mining, oil & gas and geothermal exploration projects; these include 2D and 3D TITAN 24 (DC/IP/MT) and Spartan (MT) datasets, as well as ORION 3D (DC/IP/MT). Benoit has been a key contributor to the design and development of Quantec’s ORION 3D method. His main research interests are focused on the application of magnetotelluric methods for resource exploration and definition. He develops software for survey design, data QA/QC, and also contributes to improvements on the inversion / interpretation of Quantec DCIP and MT datasets.
Jimmy Stephen – Senior Geophysicist: P. Geo., Ph.D. in Geophysics
Jimmy possesses extensive experience in land and airborne geophysical surveying, processing and interpretation. This includes many years of work with gravity and magnetic surveys worldwide, both airborne and land, including one of the largest airborne gravity and magnetic surveys ever flown, in Saudi Arabia (over 300,000 line-km). He has project managed several integrated geophysical exploration projects for oil & gas companies and other energy companies and government organizations. Some of these involved the regional mapping of sub-trappean sedimentary basins in Central India.
His skills include 2D/3D modelling of various geophysical datasets and the interpretive integration of different types of data including magnetotelluric (MT), magnetic, gravity, DC resistivity (DC) and induced polarization (IP). Jimmy specialises in gravity and magnetic data interpretation for structural identification, using various trend enhancements and modeling techniques. He is experienced with derivative techniques, Euler deconvolution and tilt derivatives.
Jimmy has conducted research on using gravity/topo data to estimate lithospheric strength and anisotropy within continental shields, published several papers in peer reviewed journals, and presented at international conferences.
Mehran Gharibi – Senior Geophysicist: P. Geo., Ph.D. in Geophysics
Mehran is experienced in mineral and geothermal exploration using magnetotelluric, electrical resistivity and IP methods. Current research interests include applying these to SAGD, heavy oil, fracking, and 4D monitoring; developing tools and protocols for joint 2D inversion of MT, DC, and IP TITAN 24 datasets; exploring inner properties of omni-directional 3D DCIP ORION 3D datasets.
Mehran possesses extensive knowledge in exploration geophysics and has published several scientific papers, including ones on these topics:
- Development of interpretation techniques for analyzing time-lapse electrical resistivity data.
- Developing 2D and 3D time-lapse ERI techniques for monitoring evolution of contaminants at remediation sites.
- Time-lapse integrated electromagnetic and electrical methods at remediation sites.
Darcy McGill – Senior Geophysicist: P. Geo. (Limited), B.Sc. Specialist Physics
Darcy has extensive experience in geophysical surveying, both in in the field and the office, airborne and ground. During the earlier part of his career he gained an excellent technical understanding of all aspects of airborne geophysical survey techniques including time-domain and frequency-domain EM, gravity, magnetics, radiometrics, GPS and co-ordinate systems, and the interpretation of such surveys. At Quantec he has applied this experience to the integrated QC and interpretation of airborne and ground geophysics. He is expert with several geophysical processing, modeling and interpretation packages, including proprietary software and techniques developed by various survey companies. His responsibilities include project management, data processing, quality control, and the integrated interpretation of TITAN 24 DCIP/MT, ORION 3D DCIP/MT, conventional DCIP, SPARTAN MT, CSAMT, and magnetic survey data in combination with legacy geophysical data and selected airborne and ground datasets.
Roger Sharpe – Senior Geophysicist: P.Geo. B.Sc.
Roger has been leading teams in the geophysical service sector for over 30 years. Having held positions as General Manager, Senior Interpreter and Manager of R&D, Roger provides clients with a broad range of technical experience for advanced interpretation, survey design and equipment development. Prior to joining Quantec, Roger was Chief Geophysicist at Battle Mountain Gold Company, and at Multi-Phase Technologies he was Senior Geophysicist in hardware and software development for 3D monitoring. Roger is responsible for quality assurance and survey integrity. Roger heads the R&D team which is responsible for maintenance and development of Quantec’s proprietary software and advanced systems including; ORION 3D, TITAN 24 and SPARTAN MT. Roger’s alma mater is Queen’s University and he is a member of APGO, SEG and KEGS.
