Unconventional Gas & Oil Fracture Monitoring
The combination of hydraulic fracturing and horizontal drilling are the key techniques that have made recovery of shale gas economically viable. Environmental concerns regarding aquifer contamination and gas migration are now threatening to limit widespread extraction of shale gas using these techniques. Meticulous monitoring during these extraction processes could allay these concerns, however, such monitoring using today’s technology is simply not affordable. At less than 1/5 the cost of conventional monitoring technology, USSI is changing the rules.

4D Reservoir Monitoring
New oil discoveries are not keeping pace with the worldwide demand for oil. To make up for this shortfall, more oil must be produced from existing fields, which dictates increased use of 4D seismic techniques (repeated 3D seismic images to monitor the movement of oil reservoir fluids over time) to increase the percentage of oil extracted. For 4D to be cost-effective, permanently-installed seismic sensors are needed. Only USSI’s fiber optic seismic sensors can meet the demanding performance, cost, and reliability requirements needed for 4D.
