Rasau is an area in Brunei. The area contains one of the two oil fields of Brunei, the Rasau Field, and a small village, Kampong Rasau, which has a population of 103.
Rasau was historically one of the first stops on the Belait River upriver from Kuala Belait towards the former district administrative capital of Kuala Balai. It was founded further inland from the mouth of the Belait River and Kuala Belait for protection against pirates. Commercial hydrocarbons were first discovered in Rasau in 1979, and production began in 1983. A blowout of one of the wells in the Rasau Field, Rasau-17 occurred in April 1989. The resulting fire lasted from 25 April to 8 May when it was finally extinguished. Rasau gained prominence in the latter half of the 20th century when a bridge was built across the Belait River providing a route to Miri in Sarawak, Malaysia without the need for any ferry crossings across the Belait River. However, the bridge was not opened until after a family of Malaysians drowned at the ferry point during heavy rain.
Kampong Rasau
The small village of Kampong Rasau is located to the south of the Rasau Bridge. It has a population of 103 and is situated further upriver from Kuala Belait towards Kuala Balai. This was formerly a village of hunter-gatherers and fishermen. The modern day Kampong Rasau serves as a suburb of the nearby Kuala Belait. Villagers residing in Kampong Rasau can obtain a special permit to waive toll payment across the Rasau Bridge. This allows the villagers to conveniently travel across the Belait River for employment opportunities. A shipyard, on the opposite bank from the Port of Kuala Belait at Kampong Sungai Duhon in Rasau, is a major source of employment for the people from the village and the greater Kuala Belait area.
Oil and gas
Rasau is dominated by the Rasau Field which is one of the two onshore oil fields in Brunei. The field is operated byBrunei Shell Petroleum and was discovered in 1979, although production from the field did not start until 1983. Most of the wells are located between the highway linking the Rasau Bridge to Sungai Tujoh in the Rasau area. However, some of the Rasau wells are on the east side of the Belait River in Kampong Sungai Duhon and Kampong Pandan. The Rasau Production Station is located in the Rasau area. Pipelines connect it to the tank farms in Seria via Mumong and to the Refinery of Seria, via Kuala Belait. Hydrocarbons from Malaysia's Asam Paya field in Sarawak, across the border from Rasau is piped into Rasau.
Transportation
The main highway from Bandar Seri Begawan to the Malaysian border passes through Rasau. The road is a single carriageway and it is surfaced. It connects the Seria Bypass and the Rasau Bridge to the 11 km road between Kampong Sungai Teraban and Sungai Tujoh. The Rasau Bridge across the Belait River is a toll bridge. The tolls ranges from B$3 for a passenger car to over $20 for a commercial long vehicle. An unsurfaced road connects the village of Kampong Rasau to the Rasau bridge. A "water taxi" can be hired at the public wharf close to the Kuala Belait market to go upriver towards Kampong Rasau and Kuala Balai. There are no airports in the village. Commercial travellers would have to travel to either Bandar Seri Begawan or Miri to catch a commercial flight.
