18”+ washout successfully navigated in a vertical well in Peru

Petromac Pathfinder is a hole finder device that can be attached to the bottom of any wireline logging toolstring. The Pathfinder mandrel is made from strong, ultra-light carbon fiber composite. The integral bow-spring centralizer ensures the Pathfinder nose is at the center of the wellbore regardless of the hole size, thereby avoiding ledges. The Pathfinder is suitable for wellbores from 6 to 26in, regardless of deviation. The Pathfinder was mobilized for a vertical well in a remote location in Peru, where, historically, it had not been possible to navigate the enormous washouts formed below the casing shoe. A standalone hole-finder system (Pathfinder) centered the bottom of the tool in a huge washout ,which permitted the toolstring to pass through seamlessly. Fig1: Pathfinder helped the toolstring to be centered in the hole and navigate a 42 m long and 18”wide washout.
