    Abstract: A method can include deriving a cloud of microseismic events corresponding to a fracturing operation in an environment by spatially locating the microseismic events in the environment via a seismic velocity model; extracting a set of fracture planes from the microseismic cloud; assigning characteristics to the fracture planes; determining a second-rank fracture compliance tensor and a fourth-rank fracture compliance tensor based on the characteristics of the fracture planes; determining a change in elastic stiffness of the environment using the second-rank fracture compliance tensor and the fourth-rank compliance tensor; and updating the seismic velocity model based at least in part on the change in the elastic stiffness of the environment or determining permeability in the environment based at least in part on fracture plane locations, orientations and apertures. Various other apparatuses, systems, methods, etc., are also disclosed.

    Abstract: Methods for determining separate velocity components of an acoustic wavefield that are incident on a distributed fiber optic sensor are disclosed. A fiber optic sensor includes fiber that is spatially distributed in non-parallel planes of a three-dimensional volume having three orthogonal axes. The fiber includes a first fiber pattern that is spatially distributed within a first plane of the three- dimensional volume, and a second fiber pattern that is spatially distributed within a second plane of the volume. The fiber patterns are interrogated separately by a distributed fiber optic interrogation system. The individual responses from each pattern are combined and processed to determine separate velocity components of the acoustic wavefield relative to the orthogonal axes of the three-dimensional volume.

    Abstract: A system where a group of substantially universal pre-manufactured explosive pellet assemblies are provided for on-site forming of shaped charges. That is, a specifically tailored liner may also be separately provided to the worksite/oilfield and combined with any one of the pellet assemblies so as to form a shaped charge having characteristics that are determined by the particular liner used. In this manner, hazardous shipping of fully assembled shaped charges may be avoided while at the same time allowing the operator a full range of shaped charge performance options based on the availability of uniquely tailored performance determinative liners that are also provided to the oilfield location

    Abstract: A fluid analyzer of a downhole tool is provided. The downhole tool is positionable in a wellbore penetrating a subterranean formation. The wellbore has a downhole fluid thereabout. The downhole tool has a housing with a flowline therethrough for receiving the downhole fluid. The fluid analyzer includes at least one optical source to pass a light through an optical window and through the downhole fluid in the flowline, at least one photodetector to measure the light passed through the downhole fluid in the flowline, and at least one optical mirror. An optical path of the light extends from the optical source to the photodetector. An optical path length is defined as a length of a portion of the optical path within the flowline. The optical mirror is positionable about the flowline, and has an optical layer selectively passing the light from the optical mirror to the photodetector whereby the optical path length may be varied.

    Abstract: A technique provides protection against unwanted conditions in wellhead structures and other structures. According to the technique, a system provides a feed through in a wellhead structure or other type of structure. The feed through may accommodate a communication line routed therethrough. A closing device is positioned in the structure at a location to enable closing of the feed through via the closing device. Additionally, a condition-sensitive device is operatively engaged with the closing device to initiate actuation of the closing device once the condition-sensitive device is exposed to a predetermined condition. Upon exposure to the predetermined condition, the condition-sensitive device initiates closing of the feed through via the closing device.
