KNOC obtained operatorship of this block in May 1992. The Rong Doi(Twin Dragon) and Rong Doi Tay(Twin Dragon West) gas fields were discovered by KNOC in March 1998. KNOC signed an interim gas sales purchase agreement with PetroVietnam in December 2004, which was finalised shortly thereafter and commenced construction works for the development of the gas field, which was completed on schedule less than two years.

Korea National Oil Corporation (KNOC) is sole operator and carries out exploration, development and production activities in Block 11-2, located 320km offshore Vietnam.

KNOC holds 75% participating interest in this block on behalf of itself and a Korean Consortium which consists of LG International Corp., Daesung Industrial Com., Daewoo International Corp., Hyundai Corp., Samwhan Corp., and Seoul City Gas Co. Ltd. PetroVietnam Exploration and Production Company(PVEP) also holds 25% participating interest in Block 11-2.

This field commenced production on December 25, 2006. Now 7 Production Wels in the fields are producing the average 171 million standard cubic feet of natural gas per day upon the buyer's gas nomination. The recoverable volume of this block is 770 billion standard cubic feet and Production will continue by 2024.

After the first discovery of Su Tu Den Field, CLJOC had consecutively successful results from Su Tu Vang(Gold Lion) in October 2001, from Su Tu Trang(White Lion) in November 2003, and from Su Tu Nau(Brown Lion) in September 2005.

In Su Tu Den Southwest field 25 production wells are now producing average 18 thousand barrels of oil per day. The Su Tu Den offshore facilities consist of the Cuulong Thai Binh FPSO, a 28 well slots wellhead platform(WHP-A), and over 2.4km of pipelines(from WHP-A to PLEM). The oil produced from Su Tu Den field is processed and stored on boarding the FPSO, a Floating Production Storage and Offloading vessel (FPSO). The Thai Binh FPSO has 1 million barrels of storage capacity. The oil produced from Su Tu Den Field is exported to FPSO.

In Su Tu Vang field 10 production wells are now producing average 6 thousand barrels of oil per day. The Su Tu Vang offshore facilities consist of the central processing platform(CPP) and a Floating Storage and Offloading vessel(FSO). The oil produced from Su Tu Vang field is exported from CPP(100 thousand barrels of processing capacity per day) to FSO(1.1 million barrels of storage capacity).

Also Su Tu Den Northeast field was completed in Apr 2010 and this field is producing average 8 thousand barrels of oil per day now.
The new development of Su Tu Trang field was completed in Sep 2012 and producing 45 million cubic feet of gas and 5 thousand barrels of condensate per day. Su Tu Nau field will commence production in 2014.

The estimated recoverable volume of Su Tu Den, Su Tu Vang , Su Tu Trang and Su Tu Nau fields is 621 million barrels and Production will last by 2023.

Block 11-2 is the first overseas operating project of KNOC. The successful production in RD/RDT fields is a milestone not only for KNOC but also for Korean oil and gas industry. Korean personnel were involved in all stages of the project, from evaluation of drilling prospects, to discovery of the accumulations of gas, to negotiating all the required commercial arrangements and designing and overseeing construction of the production facilities, which were constructed and installed by a Korean company. A successful discovery and production in Block 15-1 is also a great achievement of KNOC. KNOC actively participated from exploration to production in developing the fields. These blocks are of great significance in securing energy resources for Korea by developing overseas fields.

KNOC has diversity of experience and technology in oil and gas upstream areas like exploration, development, production and distribution.
With its experienced technology, KNOC will expand its participation in oil exploitation around the world.
