Eliminate Toolstring Hold-up on Severe Rathole Ledges

A Mexican independent operator in northern Mexico had been experiencing repeated failures to log their wells due to a large ledge inside the rathole section, where the borehole shrank from 28” to 17.5”. On multiple wells, it was impossible to pass this restriction, and logs could not be acquired despite several attempts made. To overcome this persistent issue, it was proposed to run the toolstring with the PathFinder. The operator approved the trial on the next well in the sequence. PathFinder enabled two flawless descents, even across a 10” step-ledge. The toolstring passed so smoothly that the head tension showed no significant drop, confirming that PathFinder maintained optimal centralization and avoided direct contact with the ledge. PathFinder is a standalone hole-finder that centralizes the toolstring nose, enabling smooth passage over
