42% increase in 2P reserves to 1.44 billion barrels

60% increase in CSG 2P reserves to 3,748 PJ Santos share

Santos today announced a 42% or 427 mmboe increase in its year-end 2P reserves, taking the company’s total 2P reserves to a record 1.44 billion barrels of oil equivalent.

This significant reserves increase is a result of the consistent delivery of Santos’ transformational LNG growth strategy. 2P reserves dedicated to Santos’ portfolio of LNG projects are now more than 700 mmboe or almost 50% of total 2P reserves.

The overall reserves increase was net of 2009 production of 54.4 mmboe. It represents a 2P reserves replacement ratio for 2009 of 885% and is the company’s sixth successive annual increase in its reserves position.
