Caspian Sunrise’s current principal interest is in the BNG Contract Area in the Pre Caspian basin in Western Kazakhstan, a favorable and competitive landscape. Additionally, Caspian has interest in the Munaily and Beibars Contract Areas.

Kazakhstan BNG Munaily Beibars

Caspian works with its partners to develop the assets towards either production or monetization and is constantly searching for value enhancing deals that would materially enhance the portfolio in either Kazakhstan or beyond.

In January 2011, BNG engaged Gaffney Cline & Associates (“GCA”) to undertake a technical audit of the BNG Contract Area and subsequently Petroleum Geology Services (“PGS”) to undertake depth migration work, based on the 3D seismic work carried out in 2009 and 2010.

The work of GCA resulted in confirming total unrisked resources of 900 million barrels from 37 prospects and leads mapped from the 3D seismic work undertaken in 2009 and 2010. The report of GCA also confirmed risked resources of 202 million barrels as well as Most ­Likely Contingent Resources of 13 million barrels on South Yelemes.

The depth migration work that was carried out by PGS enabled Caspian Sunrise to gain a greater understanding of some of the deeper prospects yet to be explored. Caspian Sunrise believes the greater potential exists in the pre salt prospects and has plans to drill further wells to validate this belief.

In September 2016 Gaffney Cline completed an assessment of the reserves and resources attributable to the MJF structure based principally on the results from well 143. We plan to ask Gaffney Cline to revisit these finding based on additional information from 143 and information from new wells 141, 142, 144, 145 and 146 when drilled.
