The company signed the extension contract with regulator Office Des Mines Nationales Et des Industries Strategiques (OMNIS) to extend the licences at Block 2104 and Block 3113 until November 2017, the company said.
Yanchang conducted 2D seismic surveys at the two blocks last year covering 197 kilometres and 470 kilometres, respectively, which will be processed before the extension expires.
The company concluded that, based on previous exploration, there is limited upside for the commerciality of the two blocks.
