A wellbore instrument system includes a pipe string extending from earth's surface to a selected depth in a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal channel. A power sub including an electric power source is coupled proximate a lower end of the pipe string. At least one electrically powered wireline configurable wellbore instrument is coupled to the power source in the sub.

A method and apparatus for fishing a wellbore with wired drill pipe are provided. Embodiments of the invention advantageously identify objects for removal and signal proper attachment therewith. In an embodiment, a method of fishing with wired drill pipe comprising attaching a fishing apparatus to the end of a wired drill pipe string, extending the wired drill pipe string into a wellbore, monitoring signals received through the wired drill pipe string from one or more sensors coupled to the fishing apparatus, and determining proper coupling of the fishing apparatus with one or more objects intended for removal based on the signals received from the sensors is provided.

Method of using wired drillpipe for oilfield fishing operations

Deploying systems and methods for deploying a plurality of seismic devices into a borehole comprising a cable including a plurality of inter-connected cable segments and ellipsoid seismic units with at least two rows of offset seismic protrusions to establish at least three points of contact between the seismic units and adjacent cylindrical surface of a borehole casing.
