Webinar: Microseismic Monitoring: What I have learned in the last four years

In 2016, Peter Duncan presented a two-day overview of microseismic monitoring as he understood it at that time. Over the last four years the application of microseismic data, particularly to the development of unconventional resources through hydraulic fracturing, has made great strides particularly through integration with other reservoir geology and engineering practices. In this course, Duncan will try to bring you up to date on what has been accomplished using case histories of recent projects.

EAGE E-Lecture: Virtual Seismology: monitoring the subsurface with virtual sources and recivers by Kees Wapenaar

This E-Lecture introduces virtual seismology: monitoring the subsurface with virtual sources and receivers, which is a new methodology to create virtual sources and virtual receivers in the subsurface from reflection measurements at the earth’s surface. Unlike in seismic interferometry, no physical instrument (receiver or source) is needed at the position of the virtual source or receiver. Moreover, no detailed knowledge of the subsurface parameters and structures is required: a smooth velocity model suffices. Yet, the responses to the virtual sources, observed by the virtual receivers, fully account for multiple scattering. This method is not only useful for reflection imaging but is has also large potential for monitoring induced seismicity, characterizing the source properties and forecasting the response to potential future induced earthquakes. This will be demonstrated with numerical models and preliminary real-data results.​
