Cloud-based 3D modelling technology advances exploration geophysics for improved geologic understanding and drill targeting
TORONTO April 19, 2012
Over the past decade, 3D geophysical modelling has become increasingly important to exploration around the world. The ability to convert geophysical measurements directly into 3D images of subsurface rock properties that can be integrated with other exploration information in three dimensions enables resource explorers to extract significantly more insight from geophysical data.
Integration is important, says MacLeod, because no one technique provides all the answers. "Geophysical models often need to be constrained by geological and geochemical observations in three dimensions. Our aim as explorers is to develop the most complete subsurface picture of geology and mineral systems that we can."
While effective, 3D geophysical modelling has been limited to use by expert modellers, and the ability to generate earth models with confidence has been out of reach for most geophysicists. With its VOXI Earth Modelling solution Geosoft is targeting speed, usability and accessibility to remedy this.
Behind VOXI Earth Modelling’s speed and agility is cloud technology engineered by Geosoft to conduct the complex geo-computing using powerful cloud server farms, with minimal drain on the explorer’s personal computer systems. The VOXI Earth Modelling cloud service is powered by Microsoft Windows Azure.
Included in the first release of VOXI Earth Modelling is the Geosoft Magnetization Vector Inversion (MVI) modelling technique. MVI allows the magnetization direction to vary within the model and thus take into account the combined effects of remanence, demagnetization, anisotropy and induced magnetization. The result is a more realistic representation of rock magnetization, which is the fundamental rock property measured with the magnetic method.
