Rang Dong

Rang Dong Oil Field Profile

The Rang Dong oil field is located approximately 135 kilometers southeast of Vung Tau in Block 15-2 of the Cuu Long Basin in Vietnam.
The field is situated in a water depth of about 60 meters.

The field is operated by Japan Vietnam Petroleum Corporation (JVPC), a subsidiary of JX Nippon Oil & Gas Exploration, which holds a majority stake of 46.5%.
The remaining stakes are held by Perenco (36%) and PetroVietnam (17.5%).

Japan Vietnam Petroleum Corporation (JVPC) acquired the block in October 1992.
The Rang Dong field was discovered in June 1994.
Production commenced in August 1998 after the construction of the first platform. Two additional platforms were added in 2003, increasing production capacity.
In 2012, Perenco acquired a 36% stake in the field from ConocoPhillips.

The field has three platforms: NI, S1, and E1.
Oil produced from the field is stored in the MV-17 Floating Storage and Offloading (FSO) vessel, which has a storage capacity of 350,000 barrels and a receiving capacity of 60,000 barrels per day. The MV-17 was installed in November 2008 and is owned by MODEC, leased to JVPC.

The field has been in production for over 13 years. In 2009, it produced seven million barrels of crude oil and 14 million metric cubic feet (mmcf) of natural gas.
As of 2021, the remaining recoverable reserves of crude oil and condensate are estimated at 70.71 million barrels.
Cumulative oil production from the block reached 200 million barrels by 2014.

In February 2011, JVPC and co-owners announced a pilot test for enhanced oil recovery (EOR) using CO2 injection, which was the first offshore EOR project in southeast Asia. The test concluded positively in February 2012, indicating potential to increase production and reduce carbon dioxide emissions.

Initially, associated gas from crude oil production was flared. However, an associated gas recovery and utilization project was undertaken in 2003 to reduce emissions. The recovered gas is supplied to local power generation companies through a gas pipeline linked to the Bach Ho gas pipeline.
The Rang Dong project was registered as a Clean Development Mechanism (CDM) under the Kyoto Protocol in February 2006 and received certified emission reductions (CER) for 4.49 million tonnes of emission reduction from December 2001 to December 2005.

MODEC was responsible for the engineering, procurement, construction, installation, commissioning, and operation of the MV-17 FSO, including the external turret mooring system designed and constructed by Sofec.
Other contractors involved include Pacific Energy for engineering and geo-technical services, QIS for testing pressure vessels and piping systems, PFP for supplying pipes, fittings, valves, and flanges, and Global Industries for laying gas pipelines.

The MV-17 FSO is currently in operation, with a charter period from November 2008 to April 2025, plus three one-year extension options.
PetroVietnam has requested an extension for the operators to work on the east and southeast of the field for an additional two years.
