“Our excellent full year results reflect the acceptance of passive seismic as a mainstream technology for the oil & gas industry,” Dr. Peter M. Duncan, Chief Executive Officer, said. “This was the second consecutive year that we recorded a doubling of revenue. During the year we provided expanded services to both new and recurring customers. We are extremely pleased with our 2007 performance and we believe we are well positioned for continued growth and success in 2008.”

MicroSeismic expanded its sales team in the United States, broadening its coverage in its key target market and positioning the company for accelerated revenue growth.

In recent months the Company opened a sales office in Denver managed by Caroline Guynn and expanded its Houston sales team having successfully recruited Jason Forks.

The Company previously announced the opening of a Middle Eastern Representative Office in Dubai, United Arab Emirates where it is represented by Dr. Eugene Nosal.

About MicroSeismic, Inc.

MicroSeismic, Inc. is a world leader in microseismic monitoring and passive seismic imaging. Microseismic monitoring is the practice of listening to the seismic noise emitted from a reservoir so as to directly detect such things as patterns of fluid movement, fracture development or compaction. The knowledge of such patterns will allow for improved reservoir management. Passive seismic imaging is 3-D structural imaging using existing, often naturally occurring, sound sources, rather than dynamite or vibrators. Passive seismic technology enables seismic exploration in places that are difficult to reach or environmentally sensitive. For more information, visit: www.microseismicinc.com
