... Evaluation of microseismic data allows to derive comprehensive information about the spatio-temporal extends of the stimulated reservoir volume (SRV) during hydraulic fracturing. In this work, we used an almost completely data driven method using microseismic data to characterize the SRV...

... With the updating of seismic acquisition facilities and the surge of microseismic data volume, manually picking, classifying, and labeling of first arrivals can no longer meet the current production needs. Automated, efficient, and accurate microseismic phase identification algorithms...

... The trend in analyzing microseismic data has been to expand from the simple to complex, but basic, relevant information may be lost in the attempt to extract complex evaluations. Contractor results are often opaque unless the operator takes an active interest in the acquisition and analysis...

The application indicates that the azimuthal anisotropy of instantaneous frequency computed from offset...

... 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...

... 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...

... 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...

... phases. We applied our workflow to 50 minutes of microseismic data from a hydraulic fracturing monitoring campaign. The workflow provides high-quality picks for 689 out of a total of 805 detected events by using three representative template events. We validate the time picks by comparing event locations...

... 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...
