Abstract: Embodiments provide a pressure meter testing apparatus and method that allows operations/engineers the ability to determine in-situ stiffness values of geological stratum.

Abstract: The disclosure relates to a method of evaluating characteristics of an earth formation, comprising deploying a packer assembly in a borehole penetrating an earth formation, the packer assembly comprising an instrumented inflatable packer element including fiber optic sensors; inflating the instrumented inflatable packer elements; detecting, using the fiber optic sensors, events occurring in the earth formation; and transmitting data corresponding to the detected events to a surface processing system. The disclosure also relates to a packer element and a instrumented packer assembly system. The disclosure may enable to derive formation characteristic in several configurations such as a stress test or a hydraulic fracturing configuration.

Abstract: A system and method for detecting defects in a tubular structure installed in a wellbore extending into a subterranean formation. An input image of the tubular structure contains input data indicative of a characteristic of the tubular structure. A background image is determined based on the input image. The background image contains background data indicative of the characteristic of the tubular structure associated with manufacturing of the tubular structure. A defect image is determined based on a difference between the input image and the background image. The defect image contains defect data indicative of the characteristic of the tubular structure associated with defects in the tubular structure.

Abstract: A method can include receiving well path data and geomechanical simulation data; rotating at least a portion of the geomechanical simulation data from geomechanical simulation coordinates to well coordinates associated with the well path data; determining at least one of an axial strain proxy and a shear strain proxy based at least in part on the rotating; and analyzing at least the one of the axial strain proxy and the shear strain proxy.

Abstract: A method can include receiving data that characterizes anisotropy of a formation; receiving a model that models one or more planes of weakness in an anisotropic formation; and, based at least in part on the model and the data, outputting information germane to stability of a bore in an anisotropic formation.

Abstract: A method can include receiving a geomechanical model associated with a geologic environment that includes a borehole where the geomechanical model includes a vertical dimension and lateral dimensions and where the borehole includes a lateral extent that spans a lateral distance in the geologic environment; conditioning the geomechanical model to provide a conditioned geomechanical model that includes representations of structural features based at least in part on borehole-wall image data of at least a portion of the lateral extent of the borehole; and determining a stress field for at least a portion of the geologic environment using the conditioned geomechanical model. The step of conditioning the geomechanical model can optionally include conditioning the geomechanical model to provide a conditioned geomechanical model that comprises representations of structural features based at least in part on sub-surface tool data of a substantially lateral extent of the geologic environment.

Abstract: Systems, methods, and computer-readable media for processing geomechanical data. The method may include receiving a three-dimensional model of a subterranean volume that includes a reservoir, and determining, using a processor, one or more hydraulic fracture performance attributes of the subterranean volume based in part on the model. The method may also include determining a completion quality for one or more locations in the subterranean volume based at least in part on the one or more hydraulic fracture performance attributes.

Abstract: A technique facilitates selection of underground substance storage sites. Criteria are established to enable evaluation of a plurality of underground storage sites for storing a given substance. Optimal goals or targets are determined, and the potentially numerous and varied criteria are assessed against those optimal goals. A predetermined rational method is used to process and evaluate the criteria in a manner that ultimately enables selection of a desirable storage site.

Abstract: Chlorinated olefin polymers prepared from olefin polymer base resins having I10 values of 0.05-0.8 dg/minute act as impact modifiers for vinyl chloride polymers under low to ambient temperature conditions. When vinyl chloride polymers are mixed with a preferred class of the chlorinated polymers, having chlorine contents of 20-30 percent by weight, compositions that exhibit short fusion times and low fusion temperatures are produced.

Abstract: The present invention is specifically directed to improved polyvinyl chloride compositions having excellent impact strength. In particular, the impact resistant composition comprises a) a vinyl chloride polymer, b) at least one ethylene/alpha-olefin copolymer, said copolymer having a density of 0.858 to 0.91 g/cc and having a melt index from an I10 value of 0.1 to an I2 value of 10, and c) at least one randomly chlorinated olefin polymer having a chlorine content of from 20-40 percent by weight, the feedstock for said chlorinated olefin polymer having a melt index from an I10 value of 0.1 to an I2 value of 10. Optionally, these impact resistant polyvinyl chloride compositions may have inorganic filler levels from 5 to 50 parts per hundred relative to the polyvinyl chloride polymer.
