The company holds a 67% stake in the development, while Ithaca Energy owns the remaining 33% stake.
Harbour announced plans to begin subsea activities at Talbot in March.
This included the installation of a 15km pipe-in-pipe pipeline and an electro-hydraulic chemical control umbilical connecting Talbot to Judy.
Gas from Talbot will be transported via the Central Area Transmission System (CATS) to the Teesside Gas Processing Plant (TGPP).
Oil will be exported to the Teesside terminal through the Norpipe transportation system.
Harbour Energy’s UK business unit managing director, Scott Barr, said: “The safe start-up of production at Talbot delivers on our strategy of targeting high-return, short-cycle investment opportunities around our operated hubs in the UK North Sea – on time and on budget – predictable execution is key.”
Harbour Energy highlighted in its half-year results that Talbot is on track to significantly boost production in the fourth quarter.
