Seismic data
The global energy marketplace is a continually transforming one where sometimes change is the only
thing that remains constant. In order to stay at the forefront, companies have to keep up with the
latest technologies and develop the best strategies. Not only is this the case for oil and gas
companies, but also for the companies that provide services and products to this specific industry.
In the oil and gas industry, seismic data is the primary type of data used by geophysicists. Analysis
of seismic data gives earth scientists and data specialists their first clues as to the whereabouts of
valuable resource locations. Generally, petrotechnical applications export seismic data in CGM
format, which is a two-dimensional graphic data that contains either vector objects or both vector
and image objects. The Canvas support for CGM files as well as other capabilities allow for significant
increases in company productivity and workflow.
