Hélène Binet is a geostatistician with a background in geophysics, specializing in spatial data analysis, filtering and time-to-depth conversion. She has more than a decade of international experience including working in Brasil and Norway in the Oil&Gas industry. Hélène also has experience in geostatistics applied to chemical and radiological soil contamination.

As a geostatistician and engineering consultant, she applies her experience to carrying out  exploratory data analysis, sampling optimization, geostatistician estimations and simulations, building cartography together with quantifying uncertainties and delineating contaminated surfaces and volumes. All these techniques are used to answer in the best way the client-centered needs.

Moreover, her indepth-knowledge has allowed her to become a successful product manager and also be an integral part of our training team.

Jean-Marc Chautru is a Senior Geoscientist with 30 years of experience in Geological Engineering. His main skills are in 2D and 3D geological mapping, flow modeling in porous media, facies simulations, and uncertainty quantification. He has joined Geovariances in 2013 as Consulting and Training Manager and is currently Expert Geostatistician and Senior Geoscientist.

After a Master’s degree in geological engineering, and a Ph.D. in Geostatistics, he worked in Beicip-Franlab, the consulting arm of the IFP group, for 24 years. He was first Geologist, specialized in rock-typing and geological modeling. He became Reservoir Engineer in 2004 and worked on several flow simulation projects (history match and forecasts). As Principal Advisor for Modelling, he was in charge of studies review and assistance to junior engineers. He was often involved in training sessions for national companies’ young specialists. As Project Director, he has led several integrated studies.

Thanks to his double experience in geology and reservoir engineering, Jean-Marc is mastering all the aspects of subsurface studies, from rock properties modeling to fluid flow simulations, even in the most complex cases.

In addition to his Oil&Gas experience, he has worked on resource estimations for the Mining Industry in Geovariances, mainly for Gold, Nickel, and Manganese deposits.

Jean-Marc is the technical leader of studies and training sessions conducted by Geovariances in all sectors related to subsurface modeling.

Yvon Desnoyers has now 15 years’ experience in consulting, mentoring and training as a geostatistician expert at Geovariances. His main proficiency fields are sampling optimization and radiological characterization of nuclear facilities and contaminated sites to drive decommissioning & dismantling and remediation projects.

Raphael joined Geovariances as North America Sales Manager in 2021. As a geologist, he has about 15 years of experience in the mining industry and covered all the aspects of exploration, database management (SQL, DataSched, etc.) and quality control implementation, geological and geostatistical modeling, resource estimation, production geology (open pit and underground), grade control and reconciliations. His area of expertise includes various commodities such as Gold, Silver, Zinc, Copper, Lithium, Uranium, and Nickel in various countries such as Canada, Suriname, Senegal, New-Caledonia, Brasil. Raphael has advanced knowledge in Mineral Resource Estimation and can act as a Qualified Person in accordance with the NI43-101.

Claire Faucheux joined Geovariances in 2010 as an engineering consultant applying geostatistics to environmental fields. After graduating with a diploma of Ingénieur Agronome (equivalent to Msc.) from the Ecole Nationale Supérieure d’Agronomie de Rennes, she gained experience in sampling for water quality assessment at IRSTEA as well as in geostatistics for soil pollution and air quality at MinesParisTech.

Her geostatistical and statistical expertise allows her to carry out exploratory data analysis, sampling optimization, geostatistician estimations and simulations, build cartography together with uncertainties quantification and delineate contaminated surfaces and volumes. Claire mainly applies these techniques to soil contamination and air quality, while responding to client-centered needs. Her scientific software skills include Isatis, Kartotrak and R.

As part of our experienced training team, Claire is able to offer her expertise in English as well as French.

Christianne Mariz is a senior mineral resource consultant who graduated from the Universidade Federal de Minas Gerais with a master’s degree in engineering from the Ecole Nationale Supérieure de Mines de Nancy. Her MSc thesis involved mineral resources, exploitation, and storage.

She has a decade of international experience in the mining and construction industry working in Brazil, France, and Australia. She first worked with Geovariances as a mineral resource consultant dealing with exploratory data analysis, mineral resource estimation, sampling analysis and optimization, and risk analysis for various mining companies and commodities including Nickel (lateritic), Cupper-Gold (porphyry), Cupper-Zinc (skarn), and bauxite. After a few years in Australia where she reinforced her experience in resource estimation of Caledonian Nickel deposits, she came back to Geovariances in 2021 to develop the mining business.

Following his postdoctoral project about the geostatistical characterization of contaminated soil, Pedram Masoudi joined Geovariances in 2019, with more than 5 years of experience in the earth-sciences: radioprotection, mineral, and petroleum exploration.
