Perenco is present in three associations in Vietnam, with a participation of 23.25% in block 15-1, 36% in block 15-2 and 16.33% in the Nam Con Son pipeline, generating a gross production of about 60,000 boepd.
Activities
Located about 260 kilometres off the South-East coast of Ho Chi Minh, block 15-1 is located in the Cuu Long basin and is operated by the Joint Operating Company of the same name. The production began in 2003 with the Su Tu Den field and continued with the Su Tu Vang field in 2008, and the Su Tu Den North-East field in 2010. Three years later, Su Tu Vang North East started producing.
In 2014, Perenco began operations on the Su Tu Vang North-West field. In the same year, the significant development of the Su Tu Nau field, with two platforms and ten wells, allowed the production of 50,000 additional barrels per day.
The production on the Su Tu Trang gas/condensate field began in 2012. In 2016, the process was reviewed, with new equipment and a separate compression platform, thus increase the condensat production.
The crude oil is routed to the FPSO (Floating Production, Storage and Offloading unit) Thai Binh Vietnam, with the capacity of one million barrels, to be processed and stored. The gas is exported through a 16 inches pipeline (40cm). In June 2016, block 15-1 produced 300 million barrels of oil. It is the second largest operator in Vietnam.
Block 15-2, also located in the Cuu Long Basin, comprises the Rang Dong field, of which the crude oil is stored in the MV-17FSO. The PSC (Production Sharing Agreement) of block 15-2 was approved for an extension until April 2025, opening the way to a major EOR project (Enhanced Oil Recovery) with reinjection of water and gas, acted in 2013. The full scale production began with the gas injection in November 2014. This ambitious project, the first in Vietnam, generated a significant incremental production.
For its part, the Nam Con Son pipeline, with a length of 400 km, carries 777 mcf per day. The infrastructure consists of an offshore pipeline segment with a length of 370 km, which delivers wet gas to the gas processing plant located in Dinh Co, in the Ba Ria-Vung Tau province.
The liquid is then separated, the gas is conditioned in order to respond to the specific characteristics required for its sales, before being delivered through an onshore pipeline segment of 30 km long to the Phu My gas distribution centre.
The fourth sender (blocks 05-2/05-3) delivered its “first gas” in the system in September 2013. In August 2016, the Nam Con Son pipeline safely transported and processed 70 billion cubic feet of gas to its consumers.
