The Sanjiaobei PSC covers 1,056 km2 and is contiguous with Linxing West to the north and the producing Mizhi field to the southwest. The Sanjiaobei Resource area is divided into a discovered area in the northwest supported by well and well test data, and a prospective area to the south and east where mobile gas has yet to be demonstrated. A series of faults separate the prospective area from an area further east where the formations are shallow and no Resources are assigned.

Sino Gas holds a 24% net participating interest in Sanjiaobei through its shareholding of SGE (assuming full back-in of PSC partner). SGE (SEH 49%, CNEML 51%) holds a 49% interest in the Sanjiaobei PSC. Sanjiaobei PSC partner PCCBM (subsidiary of PetroChina) is entitled to participate up to its 51%-PSC participating interest by contributing its future share of costs.

The Sanjiaobei PSC exploration period currently extends to August 2018.
