Abstract: A method is described for predicting and preventing wellbore interactions at wells that are near the injection well. The method includes receiving fiber optics data; performing object detection by detecting object-like events in the fiber optic data; and sending instructions to a hydraulic fracturing system based on the object detection. The method is executed by a computer system.

Abstract: A method is described that includes receiving one or more seismic measurements corresponding to a plurality of source and receiver locations and providing an earth model for a geologic medium having a heterogeneous tilted symmetry axis. The earth model includes a nonzero shear velocity in the direction of the symmetry axis. The one or more seismic measurements are propagated over a plurality of time-steps in accordance with the earth model and a set of energy-conservative self-adjoint pseudoacoustic equations. The set of energy-conservative self-adjoint pseudoacoustic equations describes one or more seismic wavefields.

Abstract: A system and method for processing seismic data on one or more co-processor devices that are operatively coupled to a host computing system via a communications channel. The compression of input data transmitted to the co-processor device and/or the size of the storage provided on the co-processor device may enhance the efficiency of the processing of the data on the peripheral device by obviating a bottleneck caused by the relatively slow transfer of data between the host computing system and the co-processor device or by the relatively slow transfer of data within the co-processor device between the co-processor information storage and the co-processor.
