Seismic anisotropy of shale: Inversion of microseismic data
SEG Technical Program Expanded Abstracts 2014, 2014Microseismic data recorded in downhole arrays promise a potential way of estimating in situ shale anisotropy, which can be used to verify and calibrate the results of laboratory experiments on shale anisotropy. Reversely, rock physics studies can provide constraints when estimating and interpreting seismic anisotropy of shale in microseismic dataset ...

Seismic Velocity Inversion from Microseismic Data
1997Seismic tomographic imaging is the generation of maps of the spatial variation in a seismic parameter through a rockmass. Several seismic parameters may be imaged, such as attenuation or velocity, although P wave velocity images are most common because of the relative simplicity and accuracy of the measurement. P wave velocity images may be constructed

Earth science: microseismicity data forecast rupture area.
Nature, 2005On 28 September 2004 there was an earthquake of magnitude 6.0 at Parkfield, California. Here we show that the size distribution of the micro-earthquakes recorded in the decades before the main shock occurred allowed an accurate forecast of its eventual rupture area.

Completions and reservoir engineering applications of microseismic data
SEG Technical Program Expanded Abstracts 2014, 2014Evaluating hydraulic fracturing treatments by employing passive seismic monitoring technology has become an accepted industry practice and standard in the last decade foremost for unconventional resources. Due to microseismic monitoring it is now understood that the fracture created during hydraulic stimulation greatly deviates from the planar bi-wing ...

Imaging pre‐existing natural fractures using microseismic data
Geophysical Prospecting, 2015ABSTRACTIn hydraulic fracturing treatments, locating not only hydraulic fractures but also any pre‐existing natural fractures and faults in a subsurface reservoir is very important. Hydraulic fractures can be tracked by locating microseismic events, but to identify the locations of natural fractures, an additional technique is required.
