Interferometric hydrofracture microseism localization using neighboring fracture
Hydraulic fracturing is the process of injecting high-pressure fluids into a reservoir to induce fractures and thus improve reservoir productivity. Microseismic event localization is used to locate created fractures. Traditionally, events are localized individually. Available information about events already localized is not used to help estimate other source locations. Traditional localization...
متن کاملInterferometric microseism localization using neighboring fracture
We show how interferometric methods can be used to improve the location of microseismic events when those events come from several different fractures and are observed from a single well. This is the standard setup for a multi-stage hydraulic fracturing experiment. Traditionally, in such experiments each event is located separately. Here, we adapt the interferometric approach to the problem of ...
متن کاملMicroseism source direction from noise cross-correlation
S U M M A R Y Inhomogeneous noise sources surrounding stations produce asymmetric amplitudes in crosscorrelation functions that yield preferential source directions. Here we show that preprocessing biases the dominant source direction estimate towards the source producing long-duration signals by down-weighting high-amplitude signals. Tests with both synthetic data and observations show that co...
متن کاملP-Wave Microseism Source Areas: Tracking Tropical Cyclones
8 Nonlinear wave-wave interactions generate double-frequency (DF) microseisms, 9 which include both surface waves (mainly Rayleigh-type) and compressional (P) waves. 10 Although it is unclear whether DF surface waves generated in deep oceans are observed 11 on land, we show that DF P waves generated under Super Typhoon Ioke far offshore are 12 detected by beamforming of land-based seismic array...
