Description

  • The Atla field is part of the PL102C license and is located in block 25/5. The field was developed subsea with a tieback to the existing Skirne/Byggve subsea system
  • It is connected to the Heimdal host platform located 24 kilometers southwest.
  • The Atla field is expected to produce gas at an average flow rate of 14,000 boe/d including 2,500 b/d of condensates in 2013.
  • Gas transport to the UK or the Continent via Gasled. For condensate, the plan is to use the same transport solution as Heimdal, the Forties system in the UK (via Brae).

Contractors

  • Subsea 7: Management, engineering, procurement and installation of a 7km 9,3’’ flexible flowline between the Atla and the Bygve Tee on the existing pipeline between Byggve and Heimdal, together with the installation of a 7km umbilical between the Atla Production Guide Base (PGB) and the Byggve PGB.

History

  • 2010 - Atla Gas And Condensate Field discovered
  • 2011 - The plan for development and operation (PDO) was approved by the Ministry of Petroleum and Energy
  • 2011 - Subsea 7 awarded flowline and umbilical contract
  • 2012 - Total starts-up production at the Atla field

Geology

  • The reservoir contains gas/condensate in sandstones of the Middle Jurassic Brent Group, at a depth of about 2 700 metres
  • The recovery strategy is gas depletion with one production well
