  • Publication number: 20210149790
    Abstract: The present disclosure relates to generating an event specific log file for a computer system. The generation comprises storing buffered log data in at least one memory buffer during an execution of one or more threads in real time. The generation further comprises receiving thread execution data. The generation further comprises inputting the thread execution data into an anomalous program event detector module configured to generate an anomalous program event signal in response to detecting an anomalous program execution event. The generation further comprises searching the buffered log data for event specific log data in the at least one memory buffer with a log dependency analyzer module in response to the anomalous program event signal. The method further comprises writing the event specific log data to an event specific log file using a log archive writer module.

  • Publication number: 20210055437
    Abstract: Implementations for monitoring seismic data recorded in a marine survey of a subterranean formation for coverage gaps are described herein. Implementations include computing Fresnel sum operators for Fresnel zones of the subterranean formation based on a Kirchhoff migration impulse response at horizons of a representative plane layer model of a survey area of the subterranean formation. Implementations also include computing an acceptability map of the survey area based on the Fresnel sum operators. The acceptability map reveals coverage gaps in the survey area. Geoscientist may use the acceptability map to infill seismic data in areas of the survey area that correspond to the coverage gaps.
