Daniel Silva

Ph.D. Graduate (2015)

Silva Maureira, D.A., 2015, Enhanced Geologic Modeling with Data-Driven Training Images for Improved Resources and Recoverable Reserves, Ph.D. Thesis, University of Alberta, Edmonton, Canada

Dr. Silva is a mining engineer from Universidad de Chile currently pursuing Ph.D. in mining engineering at the University of Alberta. Prior to joining the Centre for Computational Geostatistics Mr. Silva worked as Geostatistician at AMEC based on Santiago, Chile conducting mineral resource-reserves evaluations and technical reports for pre-feasibility and feasibility projects in South and Centre America.

Research

The main area of research comprises developing advanced numerical modeling techniques for improved uncertainty characterization in mineral deposits. My particular interest lies on:

  • Theory and applications of multiple point statistics algorithms to modeling complex geological settings in mineral deposits
  • Hybrid multiple point statistics models incorporating and integrating multiple training images for an accurate forecasting of recoverable resources and reserves

Mehdi Khajeh

Ph.D. Graduate (2013)

After Finishing BSc (2001-2005) and MSc (2005-2007), both in Petroleum Engineering, I Started my PhD at University of Alberta, Department of Civil and Environmental Engineering and in Reservoir Geomechanics Research Group (RG2). As Geological Modelling and uncertainty analysis of stochastical Geological Modelling processes was always my passion, I decided to consider Geostatistical Techniques in my PhD Research, but from Geomechanical Engineering side of view. I investigated how heterogeneity of in rock mechanical properties (in addition to heterogeneity of petrophysical properties which conventionally was considered in geological modelling process) have effect in SAGD. Additionally,  I developed Ranking Technique to rank geological realizations based on Geomechanical Response and also developed  Numerical Upscaling Technique for upscaling of rock mechanical properties.

CCG team and specifically Dr. Jeff Boisvert were great help and great support during my PhD. From February 2013 so far, I am working with Cenovus Energy as Geomechanical Engineer. “

Growing up in St. John’s, Newfoundland I completed my undergraduate degree at Memorial University obtaining BSc. in Earth Sciences. I have background as a professional geologist in greenfield/brownfield exploration, grade control, and resources estimation. I have experience in several different locations within Canada moving between uranium exploration, nickel-copper production & supervision, and gold production. In 2013 I decided to expand my knowledge base by joining the CCG and beginning my MSc. in Applied Geostatistics. I am an active member of the research group in the latter portion of degree completion.

Research

  • Tyler will continue to focus primarily on the mining industry in his research in geostatistics. His current interest is in practical uses of simulation in a mining context that not only provide correct estimations but also delves into accessing and using further information such as uncertainty or understanding a learning model for specific sites.
