Fishing in slim hole wells
With improved equipment and operating practices, downhole failures have decreased in all drilling operations. The cost and time to sidetrack round a fish has been substantially reduced due to improved directional drilling and surveying techniques.
This is especially true for slim hole drilled with downsized conventional equipment. A sidetrack round a fish should take one or two days of rig time and this tends to render all but the most basic fishing uneconomic.
Some of the precautions against fishing, which can be taken in slim holes include:
