Why the need for new companies?
Why the need for new companies?
• To meet government/industry aspirations (PILOT)
• E&A activity has been low for the last three years
• Loss of active exploration companies due to mergers (funding)
• Not replacing production• Maximise ultimate recoverable

Conclusions
• Full spectrum of opportunities remain
• Need to make the UK a better place to do business – stable, responsive, transparent, competitive
• Want to get licenses in hands of those who are ‘hungry and innovative’ – Brian Wilson (UK Energy Minister)
