Anisotropy Effects in Microseismic Monitoring

SPE Annual Technical Conference and Exhibition, 2009
Abstract The accuracy of microseismic monitoring is highly dependent on the quality of the velocity structure used in the analysis of the arrival time or waveform data. Because most rocks associated with hydrocarbon reservoirs are generally anisotropic, methods must be developed to circumvent the effects of anisotropy or to determine the

Microseismic Deformation Rate Monitoring

SPE Annual Technical Conference and Exhibition, 2008
Abstract Microseismic monitoring of hydraulic fractures is an important tool for imaging fracture networks and optimizing the reservoir engineering of the stimulation. The range of magnitudes of the recorded microseisms depends at the lower limit on the array sensitivity; while the upper limit varies significantly from site to site.

The known unknowns in microseismic monitoring

Proceedings, 2013
The induced seismicity has been known for over 100 years from earthquakes induced by water reservoirs and mining activity. Especially the mining provides a great insight into triggering and seismicity of faults due to redistribution of stresses as the monitoring network allows 3D distribution of receivers.

Microseismic Monitoring Methods

2012
Microseismic monitoring methods have become an important tool used in determining of deformation limits and sizes of a medium under applied stresses in earth, structure and material sciences. Today, this method having many different purposes and fields of use has borrowed a number of analysis techniques from seismology.

Effects of Microseismic Station Location on Source Location Accuracy in Microseismic Monitoring

Applied Mechanics and Materials, 2014
The deviation of microseismic station location will affect the microseismic source location accuracy in microseismic monitoring. The relationship between microseismic station location deviation and source location accuracy is studied in the paper. A global optimization algorithm, particle swarm optimization (PSO), is used to search for the source ...

Microseismic monitoring — The key is integration

The Leading Edge, 2014
Abstract Microseismic monitoring provides good spatial and temporal information about hydraulic-fracture development in unconventional reservoirs, but it is insufficient by itself to define all the important characteristics of the created fracture system.
