FractVis: Visualizing Microseismic Events
We present our efforts of applying information visualization techniques to the domain of microseismic monitoring. Microseismic monitoring is a crucial process for a number of tasks related to oil and gas reservoir development, e.g., optimizing hydraulic fracturing operations and heavy-oil stimulation. Microseismic data has many challenging features including high dimensionality and uncertainty....
متن کاملLocating a microseismic event using deconvolution
We demonstrate a technique to enhance the ability of imaging the location of a microseismic event by improving both spatial and temporal focusing. The technique improves locating a microseismic event in a velocity model for which the interface boundaries are approximate but where it has the correct mean slowness. Our method designs a signal to be rebroadcasted from the receivers, using only the...
متن کاملSensor Placement for Microseismic Event Location
Mining operations can produce highly localized, low intensity earthquakes that are referred to as microseismic events. Monitoring of microseismic events is useful in predicting and comprehending hazards, and in evaluating the overall performance of a mine design. A robust localization algorithm is used to estimate the source position of the microseismic event by selecting the hypothesized sourc...
متن کاملFocusing of elastic waves for microseismic imaging
Microseismic events generate compressive waves and shear waves which can be recorded at receivers. We present a theory that shows how elastic P and S waves separately backpropagate to the original source location. These refocused P and S wavefields are free of singularities. We also demonstrate a technique that enhances the ability to image the spatial focus for each wave type using elastic wav...
متن کاملJoint microseismic event location with uncertain velocity
We study the problem of the joint location of seismic events using an array of receivers. We show that locating multiple seismic events simultaneously is advantageous compared to the more traditional approaches of locating each event independently. Joint location, by design, includes estimating an uncertainty distribution on the absolute position of the events. From this can be deduced the dist...
