Time-lapse study of microseismic velocity and reflection imaging, A
The unconventional oil and gas industry is convinced that fractures are one of the main differentiators between a good and bad well. Though, fracture delineation within unconventional reservoirs still bares substantial uncertainty. Well logs and surface seismic data try to characterize areas in an effort to populate fracture networks. Unfortunately, logs represent near-wellbore phenomena and 3D seismic data have inherently low frequency content; you are limited to a scale of faulting that can be seen at this resolution. Microseismic data are commonly used to locate induced fractures, but their ...
