First Break, 1999
Phillips licence 018 group is testing the use of microseismic activity to understand compaction and subsidence. Monitoring in 1997 in the Cl 1a well bore showed activity rates of 5 events per hour. If part of this activity is in association with waterflood fronts, then such a high event rate, combined with good event positioning, shows the potential to

The Uniqueness of Microseismic Monitoring
Proceedings, 2011Microseismic monitoring is synonymous with shale gas development in North America: experience with shale plays suggests a high degree of variability in rock properties, subsequent completion effectiveness, and ultimately gas production and EUR. There are several modes of acquisition currently in use to obtain microseismic information which is related ...

Challenges for microseismic monitoring
SEG Technical Program Expanded Abstracts 2011, 2011We review important challenges in microseismic monitoring and interpretation of the microseismic events. We start with locations of microseismic events and the impact of temporal changes in velocity during hydraulic fracturing and consider effects of uncertainty in deviation surveys on both downhole and surface monitoring.

MICROSEISMIC MONITORING AND DENOISING [PDF]
, 2017 Microseismic data recorded by surface arrays are often strongly contaminated by unwanted noise. This background noise makes the detection and location of small magnitude events difficult. The focus of this dissertation is to develop methods for improving

Abstract Microseismic interpretation of hydraulic fracturing requires an understanding of the mechanism of the microseismic sources. Quantitative geomechanical models can predict microseismicity for quantitative comparison with field data and can be used to reconcile 3D seismic earth models, fracture engineering, and fracture ...

Impact of Geomechanics on Microseismicity
SPE/EAGE European Unconventional Resources Conference and Exhibition, 2012Abstract The proper interpretation of microseismic event patterns to estimate hydraulic-fracture geometries is critical for understanding well performance in unconventional reservoirs. Besides factors such as microseismic event location uncertainty, advanced interpretations should also include a proper understanding of the geomechanical ...

Geophysics, 2011
ABSTRACT Microseismic monitoring has become an important part of borehole completions in tight-reservoir formations. Usually, clear objectives for a microseismic survey are set prior to the data acquisition. The possibility of meeting these objectives is determined by the acquisition geometry, the target formation, the completion ...

A microseismic piezofilm sensor
IEEE CCECE2002. Canadian Conference on Electrical and Computer Engineering. Conference Proceedings (Cat. No.02CH37373), 2003Monitoring seismic activity in mines is an important issue for mine safety. This seismic activity is produced by high stress faults in the vicinity of the mining operations. To estimate the location of a radiating seismic source the acoustic pressure wave travelling through the rock must be recorded at a number of sensors throughout the mine.
