RISC completes CPR for Ophir on the proposed acquisition of Santos’ Asian assets

RISC has recently completed a project for Ophir Energy PLC (Ophir) to provide a Competent Person’s Report (CPR) on Santos Limited’s (Santos) Asian assets, compliant with the requirements of a Class 1 transaction under the Listing Rules of the London Stock Exchange, for inclusion in a circular.

The assets are the Santos operated Sampang PSC offshore East Java, Indonesia which contains the Wortel and Oyong gas fields, the Santos operated Madura Offshore PSC East Java, Indonesia which contains the Peluang and Maleo gas fields and Block 12W offshore Vietnam operated by Premier Oil plc, which contains the Chim Sáo and Dua oil fields. Over 70% of the total value of the proposed acquisition is attributable to the Chim Sáo and Dua oil fields. RISC reviewed the reserves/resources of the five producing fields in accordance with the Society of Petroleum Engineers’ internationally recognised Petroleum Resources Management System (SPE-PRMS).
