World Leader in Life-of-Field Microseismic Monitoring Installations
Traditional tools for understanding reservoir geometry and texture such as well logs, pressure transient testing, and 4D seismic imaging give only a partial, static view of reservoir complexity. Life-of-field microseismic monitoring maps the dynamic interaction of injected/produced fluids with the complex reservoir geology, providing direct measurement of hydrocarbon recovery effect.
Individual Well Drainage Area Mapping
Depletion of hydrocarbons from hydraulically stimulated shale generates significant stress changes during the first few months of production, which produce detectible microseisms. These stress changes will cause compaction of propped fractures and reactivation of connected or nearby natural fractures.
Fluid Injection Monitoring
The injection of water, steam and CO2 into a reservoir for pressure support or oil mobilization will, in most cases, provide sufficient change in the natural fracture confining stresses to initiate movement and create mappable microseismic energy. Mapping these microseismic events over time allows the operator to identify areas that are not swept due to reservoir heterogeneity or structural complexity.
Cap-Rock Integrity and Casing Failure Monitoring
Thermal operations used to produce heavy oil generate considerable stress on both the production casing and the reservoir cap-rock or overburden. Failure of the casing or cementing can produce larger amplitude microseismic events. Monitoring for these can immediately alert operators to the failure and determine the specific location.
