Rang Dong oil field is located 135km southeast of Vung Tau in block 15-2 of the Cuu Long Basin in Vietnam. The block covers 400,000 acres and is proximate to the Bach and Ruby fields.

Japan Vietnam Petroleum Corporation (JVPC), a subsidiary of JX Nippon Oil & Gas Exploration, operates the field by holding majority stake of 46.5% in the project.

The remaining stake is held by ConocoPhillips (36%) and PetroVietnam (17.5%).

In May 2011, ConocoPhillips announced plan to sell its stake in the filed.

Rang Dong has been in production for more than 13 years. In February 2011, JVPC and co-owners of the field announced to conduct a pilot test for enhanced oil recovery (EOR) from the field. It is claimed to be the first offshore EOR in south east Asia.

"Rang Dong oil field is located 135km southeast of Vung Tau in the Cuu Long Basin in Vietnam."

An agreement to conduct a 20-day pilot test in June 2011 was signed between the state owned Japan Oil, Gas and Metals National Corporation (JOGMEC), PetroVietnam and JX Nippon Oil & Gas Exploration.

As per the feasibility study, Rang Dong has a potential for increased oil production while reducing CO2emissions.

The test involves injecting CO2 into the reservoir well to improve production.

Infrastructure of Rang Dong oil field

Rang Dong has three platforms named NI, S1 and E1. Oil produced from the field is stored in MV-17, a floating storage and offloading vessel, and offloaded to tankers for export.

MV-17 was installed at the field and given the ready for first oil certificate in November 2008. The FSO is owned by MODEC and leased to field operator Japan Vietnam Petroleum Corporation (JVPC).

MV-17 has a deadweight tonnage (dwt) of 52,000 and installed at a depth of 60m inside the sea. The vessel can store 350,000bpd and receive 60,000bpd of oil.

Production of oil rates

In 2009, Rang Dong produced seven million barrels of crude oil a day and 14 million cubic feet a day (mmcfd) of natural gas.

Development of the Vietnamese oil field

Having acquired interest in block 15-2 in October 1992, JVPC discovered the Rang Dong field in June 1994. Production commenced in August 1998 after the construction of the first platform. Two more platforms, added in 2003, increased the production from 50,000bpd to 68,000bpd.

Initially the associated gas produced from crude oil production was flared at the offshore platform. To reduce the gas emission into air, an associated gas recovery and utilisation project was undertaken in 2003.

Under this project, the associated gas is recovered and supplied to local power generation companies through the gas pipeline linked to Bach Ho's gas pipeline.

The Rang Dong project was registered as a clean development mechanism (CDM) in February 2006 under the Kyoto Protocol. It has received certified emission reductions (CER) issuance for 4.49 million tons of emission reduction from December 2001 to December 2005.

Rang Dong has CER approval until November 2011 that will result in the accumulation of eight million tons of emission reduction.

Contractors

The engineering, procurement, construction and installation (EPCI) contract of MV-17 was awarded to MODEC in July 2006.

"Rang Dong has been in production for more than 13 years."

The contract also called for commissioning, operation and maintenance of the FSO for nine years, with an option of one year extension for a further five years.

MODEC was also responsible for the supply of an external turret mooring system.

The system was designed and constructed by Sofec for MODEC.

Pacific Energy was involved in the engineering and geo-technical services of the offshore field and QIS was responsible for the testing of pressure vessels and piping systems of the platforms. PFP provided the CS pipes, fittings, valves and flanges for the platform. The gas pipelines were laid by Global Industries.

Future of Vietnam's Rang Dong oil field

PetroVietnam has proposed to the Vietnam Government to allow the operators of Rang Dong to work on the east and southeast of the field for additional two years.
