Study Notes
Geostatistics and Numerical Modeling in Modern Science and Engineering
- Science historically involved extensive data collection and physical experimentation, but now focuses more on understanding and quantifying physical laws and numerical modeling for inference.
- Numerical modeling has become more important than physical experimentation in modern science and engineering.
- Geostatistics, started in the 1960s, is now applied in diverse fields such as mining, petroleum, environmental, fisheries, forestry, and environmental remediation.
- Geostatistics places emphasis on the geological context of the data, the spatial relationship between the data, and data measured with different volumetric support and precision.
- Geostatistical techniques are indispensable in resource management for creating 3-D models of heterogeneity, refining estimates of in-place resources, and quantifying uncertainty in those resources.
- Geostatistics provides tools for integrating geological interpretation, hard and soft data, and data representing different measurement supports.
- Numerical modeling aims to capture the true distribution of properties in a deposit, which is influenced by complex physical, chemical, and biological processes.
- Uncertainty in numerical models arises due to incomplete data, which can be managed and reduced by considering all relevant data.
- Conventional mapping algorithms create smooth maps, but for reservoir applications extreme high and low values have a large effect on fluid flow.
- Nevsun Resources Ltd. experienced significant impacts, including a stock drop and production forecast cut, when it revised its reserve estimates in 2012.
- ENGR 3346 introduces theoretical concepts and a design component for ore reserve estimation and geostatistical analysis, emphasizing the importance of numerical modeling and quantifying uncertainty.
- Recommended reading includes Chapter 2 of Isaaks & Srivastava (1990): An Introduction to Applied Geostatistics and AMEC Minproc (2010), Oyu Tolgoi Project: Technical Report.
