Abstract: Systems and methods for obtaining downhole images through velocity analysis may be provided. For example, systems and methods may disposing a borehole sonic logging tool into a borehole disposed in a formation, wherein the borehole sonic logging tool comprises: a transmitter configured to transmit sonic energy comprising at least one or more waveforms into a formation; and one or more receivers configured to record a sonic wave field comprising at least one or more reflected waveforms and one or more direct and/or guided waveforms. In addition, systems and methods may select a group of traces from a receiver; select a set of trial velocities from at least a sonic profile; compute a coherence value between at least two or more traces from the shifted group of traces; record the coherence value for the shifted group of traces at its initial trial velocity and depth; and determine reflections.

Abstract: A method and system for coding of a media “genome” employs machine learning models for social tagging of media titles. A media genome is a detailed description of the intrinsic elements that make up a piece of content; it is a comprehensive taxonomy that considers every impactful dimension of a film, TV episode, video short, video game, or other media title. The genome may be used by filmmakers to better understand their content, as well as that of competitors. It may also be used by entertainment marketers to better target their marketing budget for specific audiences, and by brands to determine which televisions programs and films they wish to advertise around or sponsor placements in.

Abstract: A method for computing attenuation from seismic data. The method may include measuring one or more seismic events with a distributed acoustic sensing (DAS) system to form a well log of one or more traces. The method may further include isolating a first seismic event with a tapered windowing function, performing a spectral ratio of two or more pairs of traces in the well log, identifying a velocity at each of the one or more traces in the well log, identifying an analytic correction for a gauge of the DAS system, and applying the analytic correction to the spectral ratio to form a corrected spectral ratio. Additionally, the method may include identifying a slope of the corrected spectral ratio for at least a part of the well log, converting the slope to a Q value, and identifying one or more formation properties in a formation from the Q value.
