Hydro fracture and micro seismic monitoring
To improve reservoir management, monitor seismic events caused by hydro fracturing, to gain vital information on fluid fronts, active faults, shear movements and compaction of reservoirs. This in turn will help optimise production and mitigate geomechanical risk.
The main objective for microseismic monitoring is to analyse microseismic data (events). This analysis can be done in( near) real time or off line. The analysis results will provide rapid and user-friendly information about reservoir behaviour during production and/or hydro-fracturing. Ultimately, production and fraccing operations can be optimized through this analysis.
Microseismic data can provide important information about the movement of the water fronts during fluid injection and can contribute to the mapping of small fault zones which cannot be seen in conventional seismic data. This information is vital for reservoir management, optimum re-injection of produced water and proper diagnosis and management of reservoir fluid movements.
To handle microseismic or hydro-fracture monitoring, the data analysis process can be divided into three main steps:
- Event Detection and Location
- Analysis of source parameters
- Data Integration and Interpretation
Near real-time displays of events occurring in the reservoir can be made available, as well as summaries showing the space and time distribution of the events. Event statistics like histograms, and other distribution functions are available.
