0 — 2000’ 25.6 lb/ft Grade E

2000’ — 11400’ 19.5 lb/ft Grade E

11400’ — 12000’ 6 1/4” x 2 13/16” collars

In practice two grades of drill pipe are usually available on the rig. In the North Sea 5”, 19.5 lb/ft. grade E and 5”, 19.5 lb/ft, grade G are common. The combination of these two grades plus HWDP will meet most requirements.
