Santos has produced first oil from the Van Gogh infill project in the Exmouth Basin, offshore Western Australia.
The latest announcement marks the completion of the two-well programme successfully and is set to increase the field production.
According to Santos, the Van Gogh oil field is one of three offshore developments that tie into Ningaloo Vision, the floating production, storage and offloading vessel (FPSO).
As part of the project, which started last September, two subsea wells were drilled and completed and connected into existing offshore infrastructure.
Santos managing director and CEO Kevin Gallagher said: “This programme has been a great success, enabling a lift in production from the field.”
“The campaign has also been delivered safely and efficiently, highlighting the tremendous offshore expertise we have brought into the business with last year’s acquisition of Quadrant Energy.”
Targeted to access bypassed oil not drained from the original wells, the two dual-lateral wells involved drilling of horizontal sections in the 3,500m-long reservoirs located 950m below the seabed.
The Van Gogh field started production in 2010. The nearby Coniston and Novara fields were respectively tied back to the vessel in 2015 and 2016.
Santos operates the Van Gogh-Coniston-Novara project with a 52.5% interest.
Last month, Santos announced first gas from the third and final well of the Bayu Undan infill well programme.
For the Bayu Undan gas/condensate project in the Timor Sea, the drilling programme comprised two platform wells and one subsea well connecting into existing offshore infrastructure.
