About EMGS

EMGS, the marine EM market leader, uses its proprietary electromagnetic (EM)

technology to support oil and gas companies in their search for offshore

hydrocarbons. EMGS supports each stage in the workflow, from survey design and

data acquisition to processing and interpretation. The Company's services enable

the integration of EM data with seismic and other geophysical and geological

information to give explorationists a clearer and more complete understanding of

the subsurface. This improves exploration efficiency and reduces risks and the

finding costs per barrel.
