Description
Description TypeTextDate updatedDevelopmentMaria is a field on Haltenbanken in the Norwegian Sea, 25 kilometres east of the Kristin field. The water depth is 300 metres. Maria was discovered in 2010, and the plan for development and production (PDO) was approved in 2015. The field is developed as a subsea tie-back with two templates. There are five producers and two water injectors on the field. Gas for gas lift is supplied from the Åsgard B facility via the Tyrihans D template. Sulphate-reduced water for injection is supplied from Heidrun. Production started in 2017. A PDO for Maria phase 2 was submitted in November 2022.28.02.2023ReservoirMaria produces oil and gas from massive sandstone with shale layers in the Middle Jurassic Garn Formation. The reservoir is at a depth of 3,800 metres.28.02.2023Recovery strategyThe field is produced by water injection for pressure support. The wells are equipped with gas lift.28.02.2023TransportThe well stream is routed to the Kristin platform for processing and further export together with the gas and oil from the Kristin and Tyrihans fields. Stabilised oil is transported from Kristin to Åsgard C and further offloaded to shuttle tankers. The rich gas is sent via the Åsgard Transport System (ÅTS) to the Kårstø terminal, where NGL and condensate is extracted.28.02.2023StatusProduction has been lower than forecasted since start-up due to limited vertical reservoir communication. Several measures have been taken to increase production from upper and lower Garn. The PDO for Maria phase 2 which comprises drilling of more wells will increase the recovery from mid Garn. Total recovery from the field is still expected to be lower than the original PDO estimates.28.02.2023 -
