2. Results of Crude Production

The daily average production at ADOC, QPD, and UPD reached 36 thousand barrels oil per day (hereinafter, "bopd") for 1H FY2013 (Jan. to Jun. 2013) and the daily average crude production based on working interest reached 19 thousands bopd. (Ref.: Reserves to Production Ratio: About 30 years)

3. E&P Business Outlook for 2013

In FY2013, the ordinary income of the E&P business is expected to reach \50.5 billion. (Announced on Nov. 5, 2013)

Cosmo group is one of the biggest Japanese E&P operators in the Middle East. As announced in "5th Consolidated Medium Term Management Plan (FY2013-FY2017)", it is determined to enhance further the profitability of its E&P business through commencing production from Hail Field from which is expected to reach as much as the existing 3 oil fields possessed by ADOC and expanding its business portfolio by making use of good relationships with oil producing countries.

(*1) About results of reserves estimate

The assessment of ADOC reserves which deemed to have significant impact on Cosmo's future profitability was carried out in an independent assessment by Gaffney, Cline & Associate (hereinafter, "GCA"), a leading global independent reserve auditor. Their assessment confirmed Cosmo affiliates' internal assessment of remaining reserves. The assessment was carried out in accordance with the 2007 "Petroleum Resources Management System (PRMS)" prepared by the Oil and Gas Reserves Committee of the "Society of Petroleum Engineers" (SPE), and reviewed and jointly sponsored by the "World Petroleum Congress" (WPC), the "American Association of Petroleum Geologists" (AAPG) and the Society of Petroleum Evaluation Engineers (SPEE). The assessment of QPD and UPD reserves were carried out in these companies respectively. These assessments of the reserves do not guarantee the reserves and production from them.

(*2) Proved Reserves

Proved Reserves are those quantities of petroleum, which by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations. When probabilistic methods are used, there should be at least a 90% probability that the actual quantities recovered will equal or exceed the 1P estimate. (Definition of SPE PRMS 2007 March)

(*3) Probable Reserves

Probable Reserves are those additional Reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves. When probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered will equal or exceed the 2P estimate. (Definition of SPE PRMS 2007 March)

Overview UPD holds one third of equity shares of Bunduq Company Limited which owns and assumes operatorship of the offshore concession of El-Bunduq oilfield on the border of Abu Dhabi and Qatar. El-Bunduq was discovered in 1965 by Abu Dhabi Marine Area Limited and commercial production commenced in November 1975 for export to Japan as "Lower Zakum Crude".
UPD incurs 97% of development costs for El-Bunduq (3% is incurred by BP) and thus UPD obtains 97% of El-Bunduq's production.
Cosmo Ashmore was established in 1996 and took over the exploration rights of oil acreage offshore northwest Australia. Continued exploration program led to the discovery of Tenacious oilfield in 1997 and Audacious oilfield in 2001. Currently Cosmo Ashmore is carrying out exploration in the area of AC/RL5 and AC/RL6.
