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

Excavation-induced microseismicity: microseismic monitoring and numerical simulation
Journal of Zhejiang University SCIENCE A, 2012The 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.

Microseismic depletion delineation
Interpretation, 2014Hess Corporation performed an extensive data collection project in 2011 designed to investigate infill well spacing in the Williston Basin. Using combined microseismic and pressure data collected from six observation wells and the original depleted horizontal wellbore, we identified the potential for using microseismic data to monitor the extent of ...

This paper describes a series of experiments having as their main purpose the investigation of the dynamic characteristics of soils. Waves in the soil were produced by a mechanical oscillator on top of the soil and picked up by seismometers on the surface and by pressure cells below the surface of the soil.

Microseismic Monitoring Of Engineering Structures
2nd EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1989The monitoring of microseismic activity/acoustic emissions in engineering structures allows the detection and location of preliminary instabilities that always precede a structural failure. The primary advantage of this approach is that it can be used on operational structures and provide early warning of impending failure.

GEOPHYSICS, 2011
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 schedule, and only to a lesser

High-resolution microseismic imaging
The Leading Edge, 2017We examine the feasibility of high-resolution microseismic imaging of unconventional reservoirs. Given frequencies in typical downhole microseismic data that are almost an order of magnitude higher than in seismic reflection data, a comparable increase in image resolution might be expected, bringing potential resolution of downhole microseismic images ...

We discuss the elements of a generalized processing workflow for a single well geometry. Key elements of the processing workflow including data loading, filtering, event detection, arrival picking, velocity model building, hypocenter location and magnitude estimation are explained in detail.
