Mehran Gharibi – Chief 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.

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.

Benoît Tournerie – Senior Geophysicist: P. Geo., Ph.D. in Earth Sciences – Geophysics

Benoît 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). Benoît 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.

Juan Pablo Ensinck – Regional Geophysicist: MSc in Applied Geophysics

Juan Pablo is experienced in mineral exploration in South America using magnetic, gravimetric, magnetotellurics, electrical resistivity and IP methods. He completed a B.Sc. degree in Geophysics from Universidad Nacional de San Juan, Argentina; and his Masters degree in Applied Geophysics held by Idea League, with the participation of three Universities: TU Delft (The Netherlands), ETH Zurich (Switzerland), and RWTH Aachen (Germany). He is responsible for geophysical data processing for our three South American offices: Argentina, Chile, and Perú.

Darcy McGill – 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.

José Antonio (Tono) Rodríguez, B.A., M.Sc. (Geophysics)

Tono has worked in geoscience-related industries for over 30 years, in positions ranging from a geophysical programmer and business developer for the oil and gas service industry in Calgary, to managing exploration and development projects for geothermal power generation in Central America.  While working in El Salvador and Nicaragua, Tono was principally responsible for the oversight of the exploration, construction, and commercial operation of over 220 MWe of new geothermal capacity. Since joining Quantec in 2014, he has focused on project management, quality control, and inversion of DCIP data.
