FISHING JOB : EQUIPMENT, OPERATION, AND APLICATION



FISHING JOB : EQUIPMENT, OPERATION, AND APLICATION

The term fishing applies to all operations concerned with the retrieving of equipment or other objects from the hole. Portions of the drill string, bit, drill string accessories, and inadvertently dropped hand tools are typical items which may require fishing. The most common fishing job is that recovering of a portion of the drill string left in the hole due to either its failing or becoming stuck.
The best fishing technique is elimination of the cause. Periodic equipment inspections minimize drill string failures by detecting faulty joints before they fail. The alertness of the drilling crews in detecting  crooked joints, in cleaning and lubricating tool joint threads properly, and in exercising good house keeping and safety precautions, fishing jobs do  occur frequently. Most of them are relatively simple, and the only lost is the time required to run the fishing tool and retrieve the fish. A few such jobs however, become extremely costly and time consuming and even result in the loss of the hole.
