Wintershall Holding GMBH submitted a plan for development and operation (PDO) for Maria field in the Norwegian Sea to the Norwegian Ministry of Petroleum and Energy.
Maria lies 20 km east of Kristin field and 45 km south of Heidrun field. Recoverable reserves from the field are estimated at 180 million boe (OGJ Online, Dec. 18, 2014). Production startup is expected in late 2018, along with an estimated production period of 23 years.
Planned development involves two subsea templates on the sea floor tied back to several host platforms in the area.
Maria will be linked via subsea tieback to the Kristin, Heidrun, and Asgard B production platforms.
The Maria well stream will go to the Kristin platform for processing. Supply of water for injection into the reservoir will come from the Heidrun platform, and lift gas will be provided from Asgard B via the Tyrihans D field subsea template.
Processed oil will be shipped to Asgard field for storage and offloading to shuttle tankers. Gas will be exported via pipeline to the Asgard Transport gas line to Karsto.
Operator Wintershall Norge holds 50% in the field. Partners include Petoro AS 30% and Centrica Resources (Norge) AS 20%.
