Microseismic events created during the hydraulic fracture can be compared with the FracCADE hydraulic fracture predictions.
Hydraulic Fracture Monitoring
A Solid Foundation for Informed Decision Making
StimMAP diagnostics services map hydraulic fracture systems as they are created—delivering understanding of the microseismic activity within the reservoir and allowing the operator to make informed decisions about reservoir stimulation.
Understanding hydraulic fracture geometry is key to any effective stimulation treatment as well as to improving economic viability of the well. Traditionally, reservoir monitoring information has allowed evaluation of the effectiveness of reservoir treatments after the fact.
Schlumberger now offers StimMAP services for real-time, onsite microseismic monitoring that records activity during the fracturing process. Computer imagery is used to map the activity in 3D space relative to the location of the fracturing treatment. Then the maps are animated to show progressive fracture growth and the subsurface response to pumping variations.
StimMAP LIVE
The StimMAP LIVE microseismic fracture mapping service delivers data while the fracture treatment is being pumped, with less than 30 seconds of lag time. The automatic microseismic detection and location process of the StimMAP LIVE service virtually eliminates the delay in obtaining fracture mapping results, allowing engineers to change fracture pumping procedures to improve the final geometry of the fracture. An increased understanding of the fracturing process 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.
StimMAP
The StimMAP service allows accurate characterization of the locations, geometry, and dimensions of a hydraulic fracture system. StimMAP measurements can be used to ensure optimal hydraulic fracture placement and improve reservoir development. Ultimately, this service makes it possible to optimize reservoir performance by incorporating stimulation procedures with reservoir characterization.
