Microseismic Field Acquisition & Frac Monitoring
Real-time information transforms average wells into exceptional producers, with consistent IPs and higher EURs. When it comes to optimizing production, hydraulic fracturing is the most crucial operation, and you only have one chance to do it right. Having confidence in microseismic event location is critical to success.
For the dynamic subsurface model to become predictive and operationally useful, it must incorporate information about hydraulic fractures location, orientation, and size. One useful tool for acquiring that information is microseismic fracture mapping. Ideally, a dynamic subsurface model will update in real time when fracture mapping events are received and processed so that the information can be used to support decisions in real time during completion. For that to occur, confidence in the acquisition and processing of microseismic fracture mapping must be established.
Many different methodologies exist for microseismic acquisition and processing, and though they all share some similarities the differences are crucial to the reliability of microseismic events as they are reported. Conventional microseismic event location methods consist of simplistic earthquake-like detection calculations. Alternatively, we recommend the APEX methodology, using advanced Kirchhoff depth migration principals and diffraction stacking location solutions. The volume around the treatment wellbore is gridded with image nodes based on velocity modeling using available sources such as VSP, perf shots, etc. Interactive migration solutions test each node in the model volume for as the unique location solution for each seismic event. This comprehensive analysis algorithm produces a repeatable reliable location for every microseismic event.
The microseismic fracture mapping provides locations and magnitudes of events related to the Microseismically-Stimulated Rock Volume (M-SRV). In order to constrain the M-SRV with engineering data, the dynamic subsurface model will calibrate the seismically interpreted M-SRV against net pressure mapping from stimulation completion data. The resulting solution is engineered to provide more accurate M-SRV than seismic alone can provide. The contribution of drilling, completions, and stimulation engineers should not be overlooked in the dynamic modeling process as they often have key subsurface knowledge that should be captured.
If not done in real time then our results are sent at a later date, including an engineering report and 3D visualization software package with imbedded seismic results.
