Marvin F. Glotfelty, RG, dives into the art of fishing for lost tooling by covering important considerations. While referencing drilling resources that have information on fishing tools, Glotfelty emphasizes stable borehole conditions (through use of drilling fluid if using mud rotary and collars and stabilizers to keep the hole straight) and implementing safety factors when fishing.
Glotfelty recommends taking photos of everything going in the borehole so one has an idea of what they could be fishing for in the future. Glotfelty says the art of fishing is learned through successes and failures over time. Video surveys and impression blocks can also help to define what the fish is like.
