bp starts non‑associated gas production at Caspian Sea ACG field
Key Highlights
- bp started non‑associated gas production at ACG field in the Caspian Sea.
- The gas reservoirs are beneath and above the producing oil reservoirs.
- ACG contains an estimated 4 tcf in non-associated gas recoverable reserves.
bp started non‑associated gas (NAG) production at Azeri–Chirag–Gunashli (ACG) field in the Azerbaijan sector of the Caspian Sea. This production represents the first step in developing ACG’s non-associated gas resource.
ACG is primarily an oil field, but non-associated gas reservoirs were identified beneath and above the producing oil reservoirs. ACG’s first NAG production operations began with an initial producer well drilled last year from the existing West Chirag platform into two priority NAG reservoirs: the shallower Qirmaki Upper Sand and the deeper Qirmaki Lower Sand. Both are beneath the producing oil reservoirs.
The well confirmed gas resources in the upper sand and encountered high‑pressure gas in the lower sand.
The first NAG operations are focused on the Qirmaki Lower Sand reservoir for initial well and reservoir testing. Gas and condensate produced from the well will be directed to the Sangachal Terminal via the existing ACG infrastructure through the integration of oil and gas development systems.
NAG recoverable reserves are estimated at 4 tcf with a potential upside of 6 tcf.
bp is operator of ACG with 30.37% interest. Partners are SOCAR (35.3%), MOL (9.57%), INPEX (9.31%), ExxonMobil (6.79%), TPAO (5.73%), and ONGC Videsh (2.92%).
