Microseismic Hydraulic Fracture Monitoring

StimMAP services for hydraulic fracturing monitoring record microseismic activity in real time during the fracturing process. A full range of software provides modeling, survey design, microseismic detection and location, uncertainty analysis, data integration, and visualization for interpretation, wherever and whenever decisions must be made. Computer imagery is used to monitor the activity in 3D space relative to the location of the fracturing treatment. Then the monitored activities are animated to show progressive fracture growth and the subsurface response to pumping variations.

The StimMAP service uses Petrel seismic-to-simulation software to provide accurate characterization of the locations, geometry, and dimensions of a hydraulic fracture system. Advanced processing techniques provide fracture characterization that enhances fracture models and reservoir characterization for production simulation.

Microseismic monitoring, which delivers information about the changing stress of a reservoir can be used to enhance reservoir development in tight gas completions, fault mapping, reservoir imaging, waterflood monitoring, drilling waste disposal, and thermal recovery.

StimMAP LIVE Microseismic Fracture Monitoring Service

StimMAP LIVE microseismic fracture monitoring in real time provides fracture monitoring within 30 seconds of microseismic activity. Based on proprietary coalescence microseismic mapping (CMM) that allows processing more events per minute than would be possible with hand picking, there is close agreement for the fracture geometry on the same dataset. The CMM technique provides more events because multiple arrivals can be handled in a single time window.

Accurate fracture characterization

Understanding fracture geometry is key to effective stimulation treatments and well economics. Microseismic fracture monitoring provides imaging of the geometry of a hydraulic fracture to accurately measure fracture geometry. Accurately measuring the fracture geometry offers precise data on hydraulic fracture systems to increase understanding of the fracturing process. This increased understanding in real time

• reduces well stimulation costs
• optimizes field drilling plans
• allows changes in perforation strategies and plan diversion schemes to be made on the fly.
