MicroSeismic, Inc. Awarded Contract by Whiting Oil and Gas Corporation for Buried Array Program in the Sanish Field for the Bakken and Three Forks Formations

MicroSeismic, Inc. (MSI), a leading geophysical service company providing 3-D passive seismic imaging for energy exploration and production, today announced that it has been awarded a contract for a Buried Array microseismic monitoring program in the Sanish Field by Whiting Oil and Gas Corporation, targeting the Bakken and Three Forks Formations. Whiting Oil and Gas Corporation, the wholly-owned subsidiary of Whiting Petroleum Corporation (NYSE: WLL), is a Denver-based independent oil and gas company that acquires, exploits, develops and explores for crude oil, natural gas and natural gas liquids primarily in the Permian, Rocky Mountain, Mid-Continent, Gulf Coast and Michigan basins of the United States.

MSI will install the Buried Array over a 152 square mile region in the Sanish Field in North Dakota to provide microseismic monitoring, mapping and analysis of hydraulic fracturing for Whiting’s field development program.

The system applies MSI’s patented PSET® processing and analysis to the seismic data collected by MSI’s Buried Array as the reservoir undergoes fracture stimulation. The Buried Array has been proven to offer both technical and cost advantages over other methods of microseismic monitoring. It enables operators to monitor a larger percentage of wells treated for a more complete picture of reservoir performance.

“We are excited to be working with Whiting Oil and Gas Corporation on such an important program in the Williston Basin. We expect that our Buried Array technology will help make a significant difference for their production in these formations as it has for our clients in the Haynesville Shale,” said Peter Duncan, Ph.D., Founder and CEO of MicroSeismic. “This is our first Buried Array outside of the Haynesville play, which demonstrates the broad market acceptance that this unique service offering is gaining. We now have more than 300 square miles of permanent, Buried Arrays that are either installed or currently being implemented, which will be used to monitor several hundred wells. We also have additional Buried Arrays planned for other major shale plays.”

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®

PSET®, Passive Seismic Emission Tomography, is a passive seismic monitoring, mapping and analysis process invented by MicroSeismic. 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.
