Brunei–Malaysia border Total, allowing it to resume operations in the area after suspending activities since 2003. The Production Sharing Agreement for CA2 was signed on 13 December 2010. This block is run by a consortium of PETRONAS Carigali Brunei Ltd (operator), Canam Brunei Oil Ltd. (Murphy), Shell Deep Water Borneo Ltd, ConocoPhillips & Diamond E&P B.V. (Mitsubishi). During the 15th Annual Brunei-Malaysia leaders' consultation which was held on 12 September 2011, the Sultan of Brunei Hassanal Bolkian and Malaysian Prime Minister Najib Razak released a joint statement declaring that the Brunei National Petroleum Company and Petroliam Nasional Berhad (PETRONAS) will work on
Brunei–Malaysia border Petronas Carigali Sdn Bhd and US-based Murphy Sabah Oil Co. Ltd for two areas, which Malaysia calls Block L and Block M, which lie exactly within the area claimed by Brunei as part of its continental shelf/EEZ. Later in March 2003, a Bruneian gunboat was sent to drive away a Murphy drilling ship in the area. The following month, the Malaysian navy sent several gunboats into the disputed area to block the arrival of a Total ship. After a tense stand-off involving a single patrol craft from Brunei, Total backed off and both sides stopped work in the disputed areas.
