Microseismic monitoring illuminates phases of slope failure in soft soils [PDF]

Engineering Geology, 2021
The role of microseismic monitoring in rock slope stability has been long established: large microseismic events associated with rock failure can be detected by seismometers, even at distances of a few kilometres from the source.

Excavation-induced microseismicity: microseismic monitoring and numerical simulation

Journal of Zhejiang University SCIENCE A, 2012
The volume of influence of excavation at the right bank slope of Dagangshan Hydropower Station, southwest China, is essentially determined from microseismic monitoring, numerical modeling and conventional measurements as well as in situ observations. Microseismic monitoring is a new application technique for investigating microcrackings in rock slopes.

A Validation Assessment of Microseismic Monitoring

SPE Hydraulic Fracturing Technology Conference, 2016
AbstractMicroseismic monitoring of hydraulic fracturing in unconventional reservoirs is a valuable tool for delineating the effectiveness of stimulations, completions, and overall field development. Important information, such as fracture azimuth, fracture length, height growth, staging effectiveness, and many other geometric parameters, can typically ...

Microseismic Monitoring of the Valhall Reservoir

61st EAGE Conference and Exhibition, 1999
Microseismic monitoring is an emerging technology within the hydrocarbon industry which is being driven by operator requirements for real-time information on hydraulic and geomechanical processes taking place within the reservoir in the interwell region.

Microseismic Monitoring with a Surface Array

First EAGE Passive Seismic Workshop - Exploration and Monitoring Applications, 2006
We propose an alternative to down hole microseismic monitoring that uses large arrays of surface geophones. The method presents several logistical and technical advantages over more common down hole techniques, but has its drawbacks as well. We have employed the technique in more than 16 projects to date and present here some of the results and ...

Microseismic Monitoring - Technology State of Play

Proceedings of SPE Unconventional Gas Conference, 2010
Abstract Microseismic monitoring has been largely accepted as an important adjunct to the hydraulic fracturing of unconventional gas reservoirs. Both surface and downhole methodologies are now common for the performance of such monitoring, each with its advantages and challenges. This paper discusses the state of the technology today and

Uncertainty in surface microseismic monitoring

SEG Technical Program Expanded Abstracts 2011, 2011
SUMMARY Uncertainty in a migration based approach to surface and near surface microseismic monitoring occurs in two ways: uncertainty in the validity of detected events and uncertainty in the estimated position of the event. Synthetic modelling and comparison to case studies show that sign-to-noise-ratio is a key indicator of both types of the ...

Microseismic Deformation Rate Monitoring

Proceedings, 2009
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.

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
