Other drilling locations to be surveyed are Beboli, Temu, Inai, Cenmumur, Ruku-Ruku and Memali – all offshore Sarawak.
Seven firm wells
Shell last month awarded Malaysian drilling contractor Velesto Energy an estimated $17.68 million contract to drill seven firm wells offshore Sarawak and Sabah, East Malaysia. Jack-up Naga (Dragon) 4 will perform this drilling campaign, which is expected to start between 15 August and 15 October.
Naga 4 is a premium independent-leg cantilever jack-up rig that has a drilling depth capability of 30,000 feet and can operate in water depths of up to 400 feet.
Shell earlier this year conducted a survey of many of its considered drilling locations offshore Sarawak with the vessel Salvin Explorer.

The operator was to have initially drilled the Salam-3 appraisal well on Block WL4-00, which was expected to take 25 days to complete, and this would have been followed by the Gagau-1 wildcat on the same production sharing contract. The Gagau-1 exploration well was also expected to take some 25 days.
The operator for a few years has been working on plans and engineering studies to exploit its shallow-water discoveries on Block WL4-00, which is home to the Salam field and satellite Patawali and Benum finds.
