Abstract
Systems and methods are provided for correcting distributed acoustic sensing (DAS) data. The system can receive a seismic dataset with a plurality of initial seismic phase picks and a plurality of traces, and cross-correlate each of the plurality of initial seismic phase picks using the plurality of traces as reference traces. Each initial seismic phase pick can receive a set of corrected phase picks. The system can calculate a probability density function for each set of corrected phase picks. The system can select a peak of each probability density functions as accurate seismic phase picks. These accurate seismic phase picks can be used for event location in the DAS data.
