Depth Imaging unfolds complex geology and impacts Reserves The Q4 Story Depth Imaging unfolds complex geology and impacts Reserves Mark Kemme

Summary 425 km2 seismic data from four surveys successfully merged Q8 Q4 Q1 Q5 425 km2 seismic data from four surveys successfully merged Very complex geology with major reverse faults 1 2 3 4 5 3600 3800 4000 4200 4400 4600 4800 5400 5200 5000 5800 6000 6200 5600 Divided in 5 major blocks up to 5 zones per block Rigorous velocity building approach applied: top - down & W - E Velocity updating Final migration velocities picked from scaled velocity maps

Conclusions Dramatic improvement in resolution Revised interpretation Improved fault positioning Result: Successful second well Reserves increased with 50% First gas: Dec. 2000 ( within 2.5 yr !!)
