A well located in offshore Malaysia had a challenging section that included both depleted and high-pressure zones, and the customer was seeking a stable and efficient solution for setting the casing. To drill the high-pressure zone, the mud weight would need to be increased, but would conversely affect the depleted zone above. A dogleg severity (DLS) of 3.0°/100 ft (3°/30 m) build and turn added more difficulty to the section, and previous runs weren’t able to meet the trajectory. Additionally, the customer had found that longer ratholes resulted in compromised cement jobs and hole stability issues due to a necessary second rathole run. Because of this, the customer required the rathole to be shorter than 20 ft (6 m), and it needed to be drilled in the first
