Ghana – a short oil & gas industry historyGhana – a short oil & gas industry history
1900+• early land wells find oil & gas shows only
1957 Ghana gains independence• 1970 ‐ Signal Oil discovered Saltpond Field offshore Ghana, still producing c.500 bopd via MOPU
1983 GNPC established as statutory body with E&P responsibilities• legal and fiscal framework for E&P activities
• following shallow water discoveries sub‐commercial
21st Century shift to deepwater • since 2000 ‐ Significant number of deepwater exploration wells have been drilled in Ghana by international oil companies
• June ‐ July 2007 ‐Mahogany‐1/Hyedua‐1 wells discovery g y / ythe Jubilee field
• 2008 to 2011 – discoveries at Odum, Teak, Tweneboa, Enyenra, Akassa + also Paradise (Hess), Sankofa + GyeNyame (Eni), Dzata (Lukoil)

Jubilee Phase 1 Well Construction
• Prior to 2008 Tullow had never drilled a deepwater wellassembled an experienced team and delivered!
Eirik Raude• 12 drill‐wells• 1 DST
Jubilee Phase 1 Well Construction
‐ assembled an experienced team and delivered!
• Drilled 14 new wells and re‐used 3 E&A wells‐ 47 km of new wellbore drilled
• 1 DST• 1 inj test• 1 gauge install
to do all completions+ 1 further drill‐well
• 3 year contract
Blackford Dolphin
• Drilling & completions make up ~50% of grossproject capex‐ drill‐ex ~$700 million‐ completions ~$900 million
