Peng Lai is the largest offshore oilfield ever discovered in China, identified by the government as one of the country’s most important development projects across any industry sector. 

The Peng Lai field was discovered in 1999, and lies within the 1.6 million acre Bozhong Block 11/05 of the Bohai Sea, a giant ocean bay in the northeast of the country. Six successful appraisal wells followed its discovery, with a full field development plan for a two-phase development. 

The first phase, referred to as an early oil production project, came on stream at the end of 2002 through a wellhead platform and converted FPSO. Phase two covers not only the original Peng Lai discovery in the PL 19-3 area of the 11/5 license, but also two later discoveries – PL 25-6, made in 2000, and PL 19-9, made in 2003. Production from phase two started in the first half of 2007, following installation of the second wellhead platform in the fourth quarter of the year. 

Phase two construction and installation will continue encompassing a total of five wellhead platforms (B-F), a central riser utilities platform (RUP) to which all the wellhead platforms will be tied, and a new build FPSO, which will be known as the Hai Yang Shi You 117, or the Peng Bo. This second phase is expected to produce approximately 154.7 MBOD gross.
