Abstract: A method and system for measuring strain rate at a scale shorter than gauge length are disclosed. The method includes deploying a plurality of discrete seismic receivers and a distributed acoustic system (DAS) in a borehole extending into a formation. The method further includes obtaining a first DAS measurement (DAS1) between a first position and a second position, obtaining a second DAS measurement (DAS2) between a third position and a fourth position, and obtaining a discrete seismic receiver measurement between the second position and the fourth position. The method further includes determining an DAS equivalent discrete measurement (DASeq) from the discrete seismic receiver measurement, determining a sub-gauge DAS measurement (DASsg) based, at least in part, on the first DAS measurement, the second DAS measurement and the DAS equivalent discrete measurement, and determining mechanical characteristics of the formation based, at least in part, on the sub-gauge DAS measurement.

Abstract: A method includes providing a distributed acoustic sensing (DAS) system and a fiber sample. The DAS system includes a chamber and a signal generator positioned proximate to and outside the chamber. The method further includes manipulating the fiber sample into a desired shape, filling the chamber with a freezable liquid, wherein the freezable liquid is provided at room temperature, and placing the fiber sample into the chamber. The method also includes recording a first set of room temperature baseline measurements, freezing the freezable liquid, and recording a first set of frozen baseline measurements. The method further includes performing strain-sensing measurements while the signal generator is active, and melting the freezable liquid.

Abstract: A system may include a wellbore extending a first depth into a formation. Additionally, a cured-in-place pipe liner may be coupled to walls of the wellbore. One or more fiber optic cables are embedded in the cured-in-place pipe liner to monitor a curing of the cured-in-place pipe liner and record well data. The one or more fiber optic cables may be used to continuously monitor the wellbore during a method for lining the wellbore is performed. The method for lining the wellbore may include inserting the cured-in-place pipe liner into the wellbore; forcing the cured-in-place pipe liner against walls of the wellbore; curing the cured-in-place pipe liner; monitoring the curing of the cured-in-place pipe liner with the one or more fiber optic cables embedded in the cured-in-place pipe liner; and coupling the cured-in-place pipe liner to the walls of the wellbore.

Abstract: Systems and methods are presented for determining a calibrated vertical seismic profile (VSP) with a distributed acoustic sensing (DAS) system in a borehole. The methods include obtaining a density log and an acoustic slowness log for the borehole; determining a first impedance, a DAS impedance from well log (DIL) curve, from the density log and the acoustic slowness log; obtaining a VSP dataset in the borehole; for each of the plurality of gauge lengths: determining a second impedance, a DAS from vibrations (DIV) curve, from the VSP dataset for the plurality of gauge lengths, and determining a fit between the DIV curves and the DIL curve by using a misfit functional for each of a plurality of depth adjustments. The method further includes determining the calibrated VSP by applying a preferred depth adjustment to the VSP dataset.

Abstract: A method of determining rock matrix and fracture permeability to perform a reservoir fluid flow simulation. The method includes: obtaining a petrophysical characterization of a formation sample, measuring a first and second elastic wave velocity of the formation sample at a first and second frequency, calculating an average rock matrix density and an average porosity of the formation sample, determining a set of calculated elastic wave velocities for the first and second frequencies over a range of candidate permeabilities, and determining a rock matrix permeability and a fracture permeability based on the set of calculated elastic wave velocities at the first and second frequency respectively.
