MACI Bridges Scholarly Research with Petroleum Industry
of Alberta researcher Dr Mauricio Sacchi is breaking
new ground in exploration seismology. Sacchis
research focus on seismic imaging and inversion plays
an important role in the oil and gas industry since
new developments in high-resolution imaging save time
and money for industrial exploits. Working in collaboration
with industrial leaders like Geo-X Ltd, PanCanadian
Petroleum, Veritas GeoServices and the Schlumberger
Foundation, Sacchis research group has been able
to test seismic imaging development directly increasing
interest generated in the oil and gas field.
this time, Sacchi and his colleagues are developing
new imaging and signal processing algorithms. They are
trying to further improve the resolution and quality
of seismic images. Use of high-resolution methods to
detect the spatial distribution of hydrocarbon bearing
formations will lead to substantial industry savings
and enable the accurate investigation of potential oil
and gas exploration sites. The successful development
of signal processing and imaging algorithms also play
a significant role in addressing fundamental problems
in crustal and upper mantel seismology.
and his group rely heavily on the computing capabilities
of MACI. Developing algorithms to image seismic data
is computationally intensive. This research continually
demands systems with extensive memory and storage capabilities
and the parallel processing offered through MACI provides
the confidence to carry out these research equations.
MACI infrastructure enables the successful development
of high-resolution seismic images, which heavily influence
the development of realistic elastic 3D seismic inversions.
These inversions require high-end systems with the capability
of processing terabytes of data. MACI is essential for
research in this direction.
