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.

After a tense stand-off involving a single patrol craft from Brunei, Total backed off and both sides stopped work in the disputed areas.
