Microseismic Sounding Method Tested in Taiyuan
A recent study in Taiyuan, China, tested the Microseismic Sounding (MMS) Method to assess limestone permeability for geothermal exploration. Conducted by Terravox Global Limited and Sinopec Green Energy (SGE), the experiment aimed to map subsurface structures using seismic shear wave velocities.
Key Findings
- Fault Zone Detection: MMS successfully identified a buried fault zone, confirming its ability to detect deep geological structures.
- Porosity Correlation: Areas with lower seismic velocities matched higher porosity zones, validating the method’s effectiveness.
- Unexpected Productivity Results: Contrary to expectations, wells in high-porosity zones showed lower productivity, suggesting complex geological factors at play.
Conclusion
MMS proved valuable for fault and porosity mapping, but the unexpected porosity-productivity relationship calls for further investigation. This study enhances geothermal exploration methods, reducing drilling risks and improving resource assessments.
