Neptune Energy and partners plan to develop in parallel the Duva oil and gas field and an extension designated P1 of the Gjoa oil and gas field in the Norwegian North Sea with subsea completions tied back to the Gjoa platform on PL153 (OGJ Online, Oct. 2, 2018).
Neptune Energy Norge operates both fields, where the water depth is about 360 m. It seeks to develop Gjoa P1 under the plan for development and operation (PDO) covering the Gjoa license, for which it is the operator, as a northern extension. Neptune said in a news release it plans to install a subsea template but didn’t specify drilling. An image with the news release indicates two oil and one gas wells.
Gjoa P1 recoverable resources
Neptune estimates Gjoa P1 recoverable resources at 32 million boe and expects the extension to produce
Neptune estimates Gjoa P1 recoverable resources at 32 million boe and expects the extension to produce at a maximum rate of 24,000 boe/d. Neptune has applied for a PDO for the Duva field, formerly Cara, on PL636, 6 km northeast of the Gjoa field and 12 km northeast of the Gjoa platform.
It plans to install a flour-slot subsea template and drill two oil production wells, one gas producer, and possibly another oil producer.
