bp has successfully deployed multilateral well technology (MLT) in the Azeri-Chirag-Deepwater Gunashli (ACG) field development offshore Azerbaijan in the drive to maximise recovery and sustain long-term production
The introduction of multilateral well technology is expected to play a critical role in unlocking additional reserves and extending the economic life of the ACG, one of the region’ s most mature assets. It addresses the technical challenges of drilling through complex formations, alongside increasing constraints on available platform slots. By enabling multiple reservoir penetrations from a single wellbore, multilateral wells provide one of the most effective solutions for enhancing reservoir access, improving drainage efficiency, and maximising value from existing infrastructure.
“This the first time we are applying this well design in ACG, and it clearly demonstrates our commitment to deploying the right technologies to maximise recovery from our existing assets,” said Gio Cristofoli, bp regional president for Azerbaijan, Georgia and Türkiye.
“Looking ahead, innovations such as this will be essential to sustaining long-term production and unlocking additional value. By increasing reservoir contact, improving rig productivity and operational efficiency, as well as optimising slot utilisation while making the best use of existing infrastructure, MLT is a step-change solution for well delivery in ACG. We believe it represents one of the most effective ways for us to continue delivering energy safely, efficiently and responsibly, while extending the life of this world-class asset.”
Following the successful drilling of the first MLT well – C44, the first multilateral well ever drilled in the Caspian, bp plans to drill further multilateral wells across the field. Three MLT wells, including C44 and D41, are scheduled to come online this year, with several more planned between 2027 and 2028.
bp’s development strategy focuses on deploying the optimal technology configuration for each subsurface target, to suit the conditions, which will involve combining MLT with other technologies such as horizontal drilling, advanced geo-steering, and smart completions, including sand control and inflow management, unlocking significant potential to further enhance recovery across the field.
