Malaysia’s national upstream company Petronas Carigali has lined up three of compatriot Velesto Energy’s jack-up rigs for comprehensive domestic drilling campaigns.

The charters of the three rigs — Naga (Dragon) 3, Naga 4 and Naga 6 — are together worth an estimated $128 million to subsidiary Velesto Drilling.

The contractor on Tuesday received approval of Petronas Carigali’s earlier notice of assignments for the trio of jack-ups with all three charters due to start during the third quarter.

Petronas Carigali is leasing the Naga 3, a premium independent-leg cantilever jack-up that can operate in water depths of up to 350 feet, for eight firm wells.
