Aquaterra Energy has been contracted to design and install 260 centralisers for BP Azerbaijan in its latest development on the West Chirag field platform in the Azeri-Chirag-Guneshli (ACG) oilfields in the Azeri sector of the Caspian Sea.
The contract includes pre-engineering the casing requirements and devising a centraliser package for tieback operations. Aquaterra said that the West Chirag platform has 48 drilling slots, of which 20 are deemed tieback slots. A maximum of 17 wells will be tied back to the platform during BP’s pre-drilling programme and will require centralisation.
