In 2010, ARC added 108 mmboe of P+P reserves, replacing 502 per cent of its annual production of 27 mmboe, primarily from internal development activities. Our corporate reserves increased by 29 per cent on a P+P basis to 487 mmboe and 25 per cent on a proved basis to 336 mmboe over 2009.

This growth was achieved at an all-in annual FD&A cost of $9.21 per boe excluding FDC for P+P reserves. This brings ARC’s three year average FD&A cost excluding FDC down to $8.60 per boe. ARC’s P+P F&D costs were $6.47 per boe in 2010.
