... Noise in surface microseismic data usually has complicated features, signal reconstruction from various types of noise is very challenging for existing reconstruction techniques. In this paper, we propose to use a trilateral weighted sparse coding scheme within the block matching framework...

..., extracting potential events, and quality control of the detection results. We have implemented the MF algorithm on a microseismic data set with over 19,000 events detected on two monitoring wells. The MF detection results are compared with the results from STA/LTA. The MF algorithm is more efficient in event...

... of events from a small local broadband network. In this study we integrate a high-resolution microseismic dataset from the same treatment with that previous work, and demonstrate that the microseismic data provides an even more compelling case that aseismic slip plays a role in induced seismicity...

... splitting in the raw microseismic data, so we manually picked Sv-wave arrivals of selected microseismic events and used them to constrain the anisotropic model. The average gamma parameter in the new VTI model increased to 0.2-0.25 in the target formation. The new VTI model reduced the average Sv-wave...

The swarm-like behavior of cluster 2 resumed and intensified after the 4.1 event in cluster 1. Downhole microseismic data at cluster 2 reveal a series of lineaments...

... Microseismic data is being routinely collected as part of large pad scale hydraulic fracturing developments. The large lateral and sometimes, vertical spread of the pad wells allow the possibility of correlating observations made from the microseismicity during treatment phase with known...

... Microseismic data is often used to locate fracture locations and their origin in time created by fracking. Although surface microseismic data can have large apertures and is easier to acquire than the borehole data, it often suffers from poor signal to noise ratio (S/R). Poor S/R poses...
