Event localization results obtained by various processors in downhole microseismic monitoring and their analysis

Abstract

The paper compares the processing results of four different companies for the same amount of data. The main focus of the work is related to assessing the quality of building a velocity model of the medium. It turned out that the performers used quite different models from each other, and, accordingly, received different results from each other on the example of one of the events. We analyzed the quality of localization of perforation events in these models and the quality of timing, both for perforations and for one of the microseismic events.
