South Korea’s SK Innovation has chartered China’s gas producer Sinopec’s semi-submersible drilling rig Kantan 4 for a drilling campaign in the Pearl River Mouth basin in the South China Sea.

The drilling is part of the preparation for the first oil at SK’s deep-water Lufeng 12-3 field next year.

The campaign involves two wells at the Lufeng play and includes Sinopec’s semisub Kantan 4, sources told Upstream. The rig has just completed a development drilling campaign in the East China Sea

Kantan 4, originally called Western Pacesetter 4, was built by a yard in Singapore in 1994.
