Abstract: A method of predicting three-dimensional fracture geometry in a subterranean region of interest is disclosed. The method includes obtaining a strain tensor for the subterranean region of interest, calculating a set of principal strain components from the strain tensor, and determining a strain cyclide from the set of principal strain components. The method further includes calculating a set of quadrimodal fault normal vectors from the strain cyclide and determining an in-plane shear strain magnitude and a shear strain orientation from the set of quadrimodal fault normal vectors.

Abstract: A method for measuring a strain field involves determining an expected source mechanism of the strain field, based on the expected source mechanism, estimating strain field tensors of the strain field in an area of interest, determining principal strain vectors from the strain field tensors, identifying the most extensional principal strain vectors, ε3, from the principal strain vectors, establishing a trajectory of a fiber optic path through the area of interest, discretizing the fiber optic path to obtain directions of fiber axial strain, εa, comparing εa against ε3, and based on the comparison, optimizing the fiber optic path for an alignment of εa with ε3.

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 includes a plug standard formed of a geomaterial, a fiber optic cable and a support lattice embedded within the plug standard, and a joint attached to an end of the fiber optic cable outside of the plug standard. The fiber optic cable captures at least strain measurements and temperature measurements of the plug standard. The support lattice supports the fiber optic cable within the plug standard, and the joint connects the fiber optic cable with a fiber optic interrogator.
