Abstract
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.
Claims20
A method of fishing with wired drill pipe comprising:
- attaching a fishing apparatus to an end of a wired drill pipe string, the wired drill pipe string comprising a cable communicatively coupled at each pipe joint;
- 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 one or more sensors.
A method of logging while fishing with wired drill pipe comprising:
- coupling an overshot to the bottom of a wired drill pipe string, wherein the overshot is adapted to electrically couple with an end of a well logging instrument;
- extending the wired drill pipe string into a wellbore;
- physically coupling the overshot with a well logging instrument being fished from the wellbore such that the overshot is also electrically coupled with the well logging instrument being fished from the wellbore;
- and
- receiving signals through the wired drill pipe string from the well logging instrument being fished from the wellbore.
A system for fishing a wellbore, comprising:
- a wired drill pipe string having a cable communicatively coupled at each pipe joint;
- a fishing apparatus coupled to the wired drill pipe string;
- and
- one or more sensors coupled to the fishing apparatus which may send signals through the wired drill pipe string.
