Cloud-based 3D modelling technology advances exploration geophysics for
improved geologic understanding and drill targeting
TORONTO, April 19, 2012 /PRNewswire/ - Geosoft announced the release of VOXI
Earth Modelling, a cloud-based geophysical inversion software service
that generates 3D voxel models from airborne or ground gravity and
magnetic data. VOXI is available as part of the Geosoft 2012 Software
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.
"One of the important benefits of converting gravity or magnetic data
into a 3D earth model is that the visual end product allows explorers
to see and understand the subsurface using now common 3D viewing
platforms," said Ian MacLeod, Geosoft Chief Technologist. "VOXI
produces a model of rock properties, which can be directly integrated
with other surface and subsurface geologic observations. "
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.
" We have designed VOXI Earth Modelling to fit naturally within an
explorer's workflow" said Robert Ellis, Geosoft Senior Earth Modelling
Scientist, "and we've made it fast, recognizing that speed in
generating 3D inversions is a critical requirement that will allow
geoscientists to use this tool routinely. Speed also allows us to
iteratively improve our models as we add constraints and learn more
about our projects."
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.
Geosoft VOXI Earth Modelling is being offered as a software service
extension accessible within Geosoft Oasis montaj. Visit http://www.geosoft.com/voxi to try VOXI Earth modelling or learn more about geophysical 3D
