Effectiveness of microseismic monitoring for optimizing hydraulic fracturing in California
… in California. Some of these companies use microseismic monitoring technologies to maximize production from hydrocarbon reservoirs. In this study, the effectiveness of microseismic monitoring to maximize production in California is explored. This is accomplished by comparing trends in oil …

Microseismic Monitoring of a Room and Pillar Retreat Coal Mine in Southwest Virginia
… rockmass behavior associated with the process. A microseismic monitoring system was installed in a retreat mine in Southwest Virginia to provide more information about the changing stress conditions created by retreating and ultimately reduce risk to miners. Microseismicity has been proven to be …

PORTABLE WIDEBAND MICROSEISMIC DATA ACQUISITION SYSTEM
Microseismic monitoring has gained importance ever since a correlation was established between earthquakes and intensive mining operations at various mine sites across the world. A microseismic network is in place at the Cory, Saskatchewan, mine site to record vibrations from minor tremors and to …

PetroVis & FractVis: Interactive Visual Exploration of High-dimensional Oil and Gas Data
… of two oil and gas domain case studies, namely: microseismic monitoring (in the design of FractVis) and petrographic analysis (in the design of PetroVis). For each of the case studies, we outline the necessary tasks, needs, and the challenges faced by the domain experts. By closely collaborating …

Integrative Geophysical and Environmental Monitoring of a CO2 Sequestration and Enhanced Coalbed Methane Recovery Test in Central Appalachia
… scheduled to begin Fall 2016. The design of the monitoring program for the test considered several site-specific factors, including a unique reservoir geometry, challenging surface terrain, simultaneous CBM production activities which complicate the ability to attribute signals to sources. A …

Investigation of coal bumps in the Pocahontas No. 3 seam, Buchanan County, Virginia
… mining equipment were detected using the microseismic monitoring system developed by the U. S. Bureau of Mines. Areas of high stress occurring within the panel were detected by a series of convergence points installed by the mine operator and by small diameter auger holes drilled into …

Automated seismic event location by waveform coherence analysis
… of seismic events is a very important task in microseismic monitoring operations as well for local and regional seismic monitoring. Since microseismic records are generally characterised by low signal-to-noise ratio, such methods are requested to be noise robust and sufficiently accurate. Most …

Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman
… and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better understand reservoir geomechanics. The network comprises 12 4C stations in 5 monitoring wells which can be used for focal mechanism and anisotropy studies. In this Study, …
