MicroSeismic, Inc. Granted Patent for its PSET Technology

Thursday, October 01, 2009

Houston, TX -- MicroSeismic, Inc., a leading geophysical service company providing 3-D passive seismic imaging for energy exploration and production, today announced that it has been granted a patent by the United States Patent and Trademark Office for its Passive Seismic Emission Technology (PSET®) service.

PSET® is a passive seismic monitoring, mapping and analysis process invented by MicroSeismic. It is coupled with MicroSeismic’s FracStar® array and its Buried Array product, which utilize geophones to locate very low level acoustic energy emissions associated with hydrocarbon producing activities.

"Receiving the patent for our PSET® technology is a significant accomplishment for MicroSeismic and one that we are extremely proud of," said Peter Duncan, Ph.D., Founder and CEO of MicroSeismic. "This is an important step for MicroSeismic as we have now received recognition and protection for our core technology, one which enables us to identify "real" microseismic signals in the presence of otherwise overwhelming noise. It is a key differentiator for our company as it provides unique microseismic processing and analysis capabilities not offered by any other company. PSET® raises the bar in the reservoir and frac monitoring industry."

With its PSET® technology, MicroSeismic is able to provide services such as hydraulically induced fracture mapping, the delineation of reservoir-scale faults or reservoir discontinuities, the identification of areas of reservoir compaction, injected fluid front monitoring as well as continuous reservoir monitoring. It provides an understanding of the heterogeneity of the reservoir and the geological or reservoir conditions from which hydrocarbons are being extracted which in turn enables operators to make better informed decisions in their production and hydraulic frac programs.

About MicroSeismic, Inc.

MicroSeismic, Inc. is a leading provider of passive seismic and microseismic data acquisition, analysis and interpretation to the global oil & gas industry. MicroSeismic’s technology and services enable E & P operators to better manage their reservoirs, increase their production rates and decrease their completion costs and risks.

Microseismic monitoring is the practice of listening to the seismic noise emitted from a reservoir to directly detect patterns of fluid movement, fracture development, compaction or faults. 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.

About PSET®

Passive Seismic Emission Tomography, PSET®, utilizes a FracStar® array or a Buried Array of surface detectors to locate very low level acoustic energy emissions associated with hydrocarbon producing activities. The surface array approach has the advantage of not requiring dedicated monitor wells. There are many potential sources of seismic energy from the reservoir, all associated with specific dynamic reservoir interventions. Mapping of these energy fields can yield valuable information to optimize frac treatments and other processes.
