SPE Publication: First 22” PDC Run on RSS (Kuwait)




The paper presents the successful use of a new 22" PDC bit design with an RSS push-the-bit system to drill a challenging S-shaped directional trajectory in the top hole section of a well in North Kuwait. Extensive collaboration and 3D dual UCS transition simulations were used to optimize the design for stability and steerability in interbedded formations. The optimized PDC bit achieved a 60% faster ROP compared to offset wells, excellent directional response, and set a new ROP benchmark. This milestone run represents the first S-shape RSS application worldwide in 22" hole and the first 22" RSS directional system in the Middle East, enabling more complex well trajectories and field development. The project highlights the value of advanced simulation tools in achieving new drilling innovations.
