Why secondary humps?:
Stratigraphic traps:
Scapa, Blake, Buzzard

Future:
Golden Eagle hub, PDL & exploration
OMF Annual Oil Production by Hub
Strat trap & fault

Palaeozoic around
flanks
Many fields are mature and demonstrate low but steady decline
Modern fields demonstrate higher decline rates. (Note cumulative effect)
Emphasises the importance of major finds (Exploration!!)
Input Model database arranged in hubs, LOF production-to-date, needs forecast

Annual Oil Production
Is there another hump to
come?: PDL, Golden Eagle
& future exploration.
OMF has produced 400,000 - 450,000 BOPD over majority of last 40 years
1stSOM
Average: 4 wells per year
Average: <2 wells per year
4 E&A wells per year to <2 E&A wells per year in Q14 & Q15
How many deep exploration wells or testing new plays?
