(*2) Provisional means the connection has been tested and appears to be technically satisfactory, but needs field evaluation prior to final approval. Please contact EPTG Drilling prior to using any Provisional connection. (*3) Hydril CS/CS-CB, Benoit BTS-8/BTS-8PR, HI TS-HP/TS-HP-SR, and GP RTS-8/RTS-8PR are equivalent connections. The Benoit, Hunting, and Grant Prideco connections are interchangeable with the Hydril connection, but NOT with each other.
