Premier Oil is making progress with plans to develop the Laverda field in the Greater Catcher Area.
The London-headquartered firm hopes to develop Laverda with a single production well connected to a new subsea pipeline.
The line would be shared with the nearby Catcher North development.
Liquids would be processed on the Catcher floating production, storage and offloading vessel.
Laverda is located 105 miles east of Aberdeen and has recoverable reserves of 2.8 million barrels of oil.
Premier has now submitted a letter of application to give the Oil and Gas Authority “preliminary notification” of its proposals.
The application is supported by an environmental statement and the public consultation is open until January 21.
Project sanction was anticipated in the first quarter of 2019, with development activity also due to commence next year.
First oil is slated for early 2021.
The field has an estimated production life of four years.
Premier has 54% of Laverda, Nautical Petroleum has 36% and Dyas UK is on 10%.
