SLIDE 22 Reserves and resources at 31 December 2011
No external reserves audit this year:
Field production performance consistent with predictions through 2011 Currently well advanced on building new reservoir models that will allow
- ptimisation of production during gas depletion – will highlight additional
- pportunities
Audit in 2012 will include updates for recent successes in development drilling and near field discoveries
2011 production of 6.7 mmboe led to:
Proven (1P) net remaining oil and gas reserves decrease from 336.8 mmboe to 330.1 mmboe Proven and Probable (2P) net remaining oil and gas reserves decrease from 559.3 mmboe to 552.6 mmboe
2C contingent resources, comprising oil, gas and associated liquids unchanged from 2010 at 317.7 mmboe Total 2P and 2C reserves and resources of 870 mmboe, down from 877 mmboe in 2010 after 2011 production of 6.7 mmboe
