Tool Taxis and Pathfinder Enable Gravity Descent in Highly Deviated Wells in Guyana

In Guyana’s deepwater wells, deviations of 60–70° had traditionally required TLC conveyance, adding risk and costly rig time. Petromac Tool Taxis improved efficiency by reducing drag and enabling gravity descent, but severe washouts still caused tool hang-ups. The solution was the addition of the Pathfinder centralized hole-finder , which guided the toolstring smoothly through ledges and washouts. On its first run with a CMR–MDT combination, Pathfinder enabled full gravity descent to TD through a 1,500 ft tangent at 66°. In addition, taxis ensured zero sticking even on an 8.5-hour MDT station. Overall, by avoiding pipe-conveyed logging, the operator saved ~2 days of rig time, translating into substantial cost savings while ensuring safe, reliable data acquisition. Tool Taxis combined with a centralized Pathfinder enabled safe gravity descent reducing rig time and
