Abstract: A method for processing distributed acoustic sensing (DAS) vertical seismic profiling (VSP) data is provided. The method includes operations to receive DAS data associated with an optical fiber's response to seismic energy applied by three seismic energy sources. The three seismic energy sources each configured to apply seismic energy to the optical fiber in a direction that is orthogonal to a direction of seismic energy applied by the other two seismic energy sources, the optical fiber is at least partially positioned within a wellbore, and the DAS data includes three components directed in an axial direction of the wellbore associated with energy application by the respective three seismic energy sources. The method further includes operations to apply reciprocity to the three components to model an equivalent vertical point force source in the wellbore with receivers configured to receive the three components at a location of the respective three seismic energy sources.

Abstract: A sensing system may comprise a deployment device having an optical fiber cable with a predetermined curvature or an intrinsic curvature. The sensing system may be deployed into a location that is remote or difficult to navigate, for example, a large vessel or a borehole of a well. A deployment device may deploy the optical fiber cable and a tension control tool may maintain the deployment device along with the optical fiber cable in a straight or non-curved shape until the optical fiber cable has reached a predetermined location or position. A force may then be applied to the optical fiber cable to cause a portion of the optical fiber cable to contact an interior wall of the area or location, for example, a borehole or the deployment device. Measurements may be retrieved from the optical fiber cable, for example, measurements used in distributed acoustic sensing in vertical seismic profiling.

Abstract: A method of performing acoustic logging comprises generating a first acoustic signal from a first source at a first time, wherein the first source is a first distance away from a wellbore wall, and generating a second acoustic signal from a second source at a second time, wherein the second source is a second distance away from the wellbore wall. The difference between the first time and the second time depends on a calibration value.
