9 CGGVeritas Sommaire Introduction: les grandes orientations de l acquisition sismique terrestre Projet Qatar Petroleum: les grands enjeux La solution intégrée CGGVeritas Conclusion

10 Introduction to Dukhan Field Large onshore field located along the west central coast of Qatar, established in 1941 Over 700 wells producing from 4 major reservoirs; development has staged: natural depletion, water flood and gas cap injection QATAR Future development will be driven by understanding complex static-dynamic models of specific reservoirs Dukhan Field Doha New geophysical data is a starting point for enhancing these models

11 Mature reservoir The Challenges of the Dukhan Project Natural depletion Development has staged A new reservoir model needed Complex surface conditions Industrial areas and Sebkha Desert and transition zone High resolution wide azimuth Unprecedented volume of data Heavy logistics (super crew) Implementation of latest technologies Field data management, QA & QC Leading edge equipment implementation Integrated surface/downhole acquisition Integrated processing & imaging

15 The Challenges of the Dukhan Project 863 sq.km 2,909,044 source points 3.75m x 3.75m bin 40,000 Sercel channels with single geophone 2TeraBytes of data per day (4,000 CDs) 3 different energy sources 24 hour operations 24 months of recording The Challenges of the Project in Numbers 700 km of telemetric cables 2,000 solar panels (110KVA) 17 Nomad65 Sercel 92 vehicles 20 vessels 120 trailers 11,000 km driven per day 12 tons of diesel per day 55 tons of water per day 2 tons of food & drinks per day 370 junior employees 60 managers/technicians 30 nationalities 320,000 working hours/month Over 5 Mh worked without LTIs

16 Energy Emission Vibroseis 12 in simultaneous recording Air Gun 920 cu.in / 460 cu.in / Mini Source Explosive Single hole 10m depth

17 The Challenges in Scope and Location 164 km² Airgun Transition 0-12 m 669 km² Vibroseis No night vibration Extended vibration hours 24 hr vibrator operations 30 km² Explosive Sekkra

18 Swath examples Shooting plan (SP) Areas Planning: Operations Schedule Area by Area Recorded 1x Recorded 2x Recorded 3x Recorded 4x SP 1 RP

19 Real Time DGPS Positioning Reference positioning network Mapping (including access, hazards, exclusions, safe operating corridors) Check offsets Support VSP Erect permanent markers

20 Recording Data Laying geophones and seismic cables ahead of recording Connecting batteries & solar panels Monitoring of ground equipment with the recording truck (24 hours) Management stakeless recording of 3 fleets of 4 vibrators Troubleshooting (24 hours) Picking up ground equipment after recording for redeployment by front crews

21 Sebkha & Tidal Areas Tractor and track drilling of shotholes in sebkha, casing holes in advance of recording operations Monitoring of tides and water levels to deploy recording equipment Monitoring of explosive daily deliveries, loading of seismic explosives and electric detonation for seismic data recording Cleaning of shothole sites by green crew Logistic by special low ground pressure vehicle when possible if all equipment is not hand carried in and out

22 Combined Surface & Massive 3D Vertical Seismic Use VSPs to improve reservoir knowledge and refine surface seismic processing parameters In partnership with Baker Hughes 8 Massive 3D VSPs Sercel Maxiwave 100 levels tool Recording unit synchronized with seismic recorder Record all surface seismic channels within 2 km radius of the well location (30000 VP)
