Partners in the Azeri-Chirag-Gunashli (ACG) Full Field Development Project made a decision on sanctioning the Phase 3 east manifold subsea water injection project, Trend reports. The east manifold will inject another 200,000 barrels of water per day into the Deepwater Gunashli reservoir through four subsea wells drilled from a single subsea drilling centre. The engineering and procurement is 20% complete with the delivery of all equipment (except flexible flow lines) on track for 2007
Delivery of the Phase 3 north and south flank subsea equipment to Baku commenced in June this year and the site integration tests (SIT) began at the end of September Two piles have already been installed for the North and South subsea manifold locations using the Dada Gorgud. These facilities will inject over 400,000 barrels of water per day into the Deepwater Gunashli reservoir through six subsea wells drilled from two subsea drilling centres approximately 5km away from the Deepwater Gunashli platform.
On subsea pipe-lay and installations, McDermott, a contractor for BP, has laid 18 subsea pipelines to date totaling over 900km in length since the start of ACG phase 1 subsea pipelines construction (including 274km for Shah Deniz) using the Israfil Huseynov barge, and by the end of the pipe-lay programme we will have installed 21 pipelines totaling about 1000km in length. For this purpose we will have used over half a million tonnes of pipe
The remaining subsea pipelay work for the project is completion of the 16 East Azeri water injection line (4.5km) and connection of Phase 3 platforms' two 30and one 28 lines with the existing two 30 crude oil and one 28 gas export pipelines.
