ELGIN FIELD LAYOUT Presentation title - Place and Country - Date Month Day Year 3
ELGIN: KEY FACTS & FIGURES Operated by Total for 8 x JV partners Elgin PUQ (Production Utilities Quarters) & wellhead platforms linked by 90m bridge High Temperature/High Pressure fields On stream since 2001 Produces 135k boe/d 4
ELGIN G4: WELL ARCHITECTURE On Elgin A (wellhead) platform Seabed @ 93m below platform Chalk HOD non-producing low permeability high pressure Fulmar producing high permeability lower pressure 5
ELGIN G4 LEAK: DAY ONE (25 MARCH) 12.20: gas & condensate leak confirmed at the wellhead on Elgin s G4 well 13.30: evacuation begins of Elgin and the adjacent drilling rig 16.40: 219 people have been evacuated, leaving 19 still on the complex 01.45: Elgin OIM decides to fully abandon Platform, rig & wells shut down Export pipelines isolated 02.30: the last 19 people are evacuated All 238 people safely and quickly evacuated 6
ELGIN G4 LEAK: INITIAL RESPONSE Informed all appropriate Authorities Mobilised Emergency & Crisis Response Teams Oil Pollution Emergency Plan (OPEP) activated Enforced sea & air exclusion zones (2 & 3 N miles) Mobilised a fleet of safety & support vessels mainly Guard, FIFI & ROV vessels Specialists WWC were mobilised early to assist Dispersant ships and planes put on standby Mobilised well control specialist WWC to assist Mobilised Oil Spill Response Limited (OSRL) and started frequent monitoring flights (2/day) Mobilised Blow Out Task Force from Total HQ Activities controlled sequentially by detailed risk assessment, many of which were reviewed by authorities The Ocean Ness Emergency Response & Rescue Vessel 7
ELGIN G4 LEAK: INITIAL IMPACTS Gas, condensate & mud released via D annulus Condensate & mud fall to sea Sheen covers a large area of sea surface Waxy paraffinic deposits on wellhead platform 8
ELGIN G4 LEAK: INITIAL IMPACTS 7 April surface sheen still visible, but less than 1/10 th micron thick 27 March gas plume and sheen visible, but not obvious 9
Elgin G4 leak: environmental impacts Environment Monitoring Activities 2 Oil Spill Response Limited (OSRL) flights per day to monitor marine pollution Regular survey flights by the National Centre for Atmospheric Science (NCAS) Daily water samples taken in Elgin surroundings Regular ROV surveys of seabed around conductor pipe Leak flow rate estimated at an initial 2kg/s but quickly fell to less than 0.6kg/s Gas composition: 70% methane + 30% ethane, butane, etc; no H2S traces Surface sheen extended many kms, but was less than 1/10 th of a micron thick Light condensate that disperses naturally and easily: 50% evaporation in the first 24 hours alone Several independent chemical, sediment and & fish analyses confirmed no direct marine contamination (eg, Scottish Government, etc) Widespread consensus that the environmental impacts are minimal 10
ELGIN/FRANKLIN: PIPELINE SYSTEM back Elgin PUQ shutdown and isolated from pipeline systems 11
SAFETY STATUS Full POB (138) re-established on PUQ Normal ISSOW and risk assessment processes re-established Required SCEs now essentially operational on PUQ and on WHP Essential CAT A maintenance re-established by crew. 3 Senior Management Briefings have been made to offshore crew in recent weeks involving both TEPUK and Rowan. Surface exclusion zone still in place, but only to control abnormal access to area, otherwise normal operations resuming. Air exclusion zone gone. Preparation ongoing to install Elgin B jacket in late September by S7000 HLV. Ongoing involvement of HSE & DECC they remain very supportive Normal Operations Resuming Presentation title - Place and Country - Date Month Day Year 13

G4 ENVIRONMENTAL RESPONSE: MONITORING Twice daily aerial surveillance flights for sheen quantification 115 flights will have been undertaken by the final sortie planned on 6 th June OSCAR Modelling from DGEP/HSE/ENV informs flight plans and alerts to neighbouring installations / transboundary lines if required. OSIS modelling linked to aerial surveillance findings supports condensate release rate calculation and daily PON1 updates to DECC Satellite imagery DGEP & OSRL Protocol developed for daily sampling of sheen / waxy deposits from sea surface. Wax / mud samples taken from Elgin WHP. Sample analyses undertaken by Intertek, FGO & CEDRE confirmed weathered condensate and with HOD condensate characteristics Short, medium and long-term survey and Environmental Impact Assessment scope of work shared with DECC, Marine Scotland and Government Interest Group (GIG) Environment Group TEPUK Onshore Emergency Response, 30/05/2012, Aberdeen 23
G4 ENVIRONMENTAL RESPONSE: SPILL COMBAT READINESS Hercules and Nimbus aerial dispersant application system pack, plus air crew and OSRL personnel on standby at East Midlands Airport throughout incident (returned to normal service once well killed) 44m3 of dispersant strategically located at Inverness airport (airside) FiFi vessels available to hose sheen if required Other vessels available to prop-wash or use dispersant sprayers to spray water to speed up dispersion if required 2 containment & recovery systems in the field (reduced to one post-kill) with back-up system portside if required. 24
