There are also some proceeds from the sales of the by-products, which were held by CNOOC. Primeline and its affiliate company Primeline Petroleum Corp. (“PPC”) today received their shares of all the sale proceeds to end of the first week of December 2014. The total amount received by the Company and PPC is RMB187.7million, or US$30.5 million and the Company’s share is US$22.9 million. Future gas sale proceeds will be transferred by CNOOC on a weekly basis.

Victor Hwang, Chairman and President of Primeline commented: ‘Having earlier announced that we have repaid CNOOC for cash calls advanced during development, I am delighted that the Company has now reached the milestone of first revenue from operations on LS36-1. 2014 has been a key delivery year for Primeline – the gas field development completed, our development obligations settled and strong trial production since July. We now look forward to progressing our exciting plans for rolling development in 2015 and beyond in order to capitalise on the infrastructure we built in LS36-1 gas field with CNOOC’.
