Quantec’s Technical team has a vast collective amount of experience. Our core team is made up of Professional Geoscientists that have worked in the area of data analysis and interpretation most of their careers.

Mehran Gharibi – Head of Interpretation Dept. 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.

Saman Perera – B.Sc., M.Sc. (Mineral Exploration)

Saman has over 27 years of experience in geology – geophysics integration for mineral and groundwater exploration, and geological mapping over metamorphic and sedimentary terranes. His areas of expertise include survey planning, acquisition, modeling and interpretation of potential field, DCIP, MT and marine seismic data. With the Quantec Interpretation Group since 2009 he has worked mainly on 2D and 3D inversions, and geological interpretation of TITAN 24, SPARTAN, and ORION DCIP and MT data. His previous positions include Senior Geophysicist, Geological Survey of Sri Lanka, and Geophysicist, Continental Shelf Delimitation Project, Sri Lanka. Saman is also experienced in monitoring seismic activities related to earthquakes, tsunami and landslides, and has worked in Canada, Sri Lanka and the Netherlands.

José Antonio (Tono) Rodríguez, P.Geo., 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.

Jeff Warne – Geophysicist: B.A.Sc. (Geophysics option)

Jeff commenced his career in 1981 after attending Queen’s University. Initially based in Vancouver with Lloyd Geophysics he was responsible for acquisition of 100’s of kilometers of time domain IP data at Pine Point Mines on behalf of Cominco. He subsequently joined Quantec where has worked for over 25 years and was involved with the initial IP data acquisition at Collahuasi in South America contributing to the discovery of the Ujina deposit. Jeff now works in the interpretation department at Quantec. He provides analysis and interpretation of DCIP data as well as gravity, magnetics and EM. Jeff has a wealth of experience in survey logistics and survey design.

Leduar Ramayo Cortes – Geoscientist: PhD in Geology and Geophysicist

Leduar is experienced in mineral and oil and gas exploration using magnetotellurics, electrical resistivity and IP methods. He possesses extensive knowledge in exploration geophysics and has published several scientific papers, including ones on these topics:

Deep IPDC and MT Imaging For Exploring Porphyry Deposits
Geophysical Exploration in Lithium Salars.

His responsibilities include business development and integrated interpretation of TITAN DCIP/MT, ORION 3D DCIP/MT, conventional DCIP, SPARTAN MT, CSAMT, and magnetic survey data in combination with legacy geophysical data and geology datasets.
