Oil major Shell has stated that it had made its fourth oil and gas discovery in a joint venture with Malaysia’s Petronas Carigali and US-based ConocoPhillips in deep water off eastern Sabah state.

The Pisagan-1A exploration well, located in Deepwater Block G northwest of the Malaysian state of Sabah on the island of Borneo, encountered both oil and gas after being drilled to a water depth of 1,465 metres, Shell said in a statement.
“We are pleased to be able to announce our fourth successive deep water oil and gas discovery offshore Sabah,” Wouter Hoogeveen, Shell's vice-president for exploration in Asia Pacific, said in a statement.
Shell said it held a stake of 35 percent in the so-called Block G, while ConocoPhillips (East Malaysia) owned 35 percent and Petronas Carigali, a unit of Malaysia’s national oil firm Petronas, 30 percent.
Meanwhile, Nigerian troops battled militia fighters in swamps around a Royal Dutch Shell PLC oil platform that militants had attacked last week, the third assault on Shell oil facilities in less than a week in the troubled region.
