About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Maria 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 has initially been developed with two templates with five producers and two injectors, tied-back to the Kristin 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. The production started in 2017. An amended PDO for Maria Phase 2, which comprises further development of the field with a new template with three production wells and one injection well, was approved in 2023 and started production in 2025.
- Reservoir
- Maria produces oil and gas from massive sandstone with shale layers in the Middle Jurassic Garn Formation. The reservoir is at a depth of 3800 metres.
- Recovery strategy
- The field is produced by water injection for pressure support. The wells are equipped with gas lift.
- Transport
- The 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.
- Status
- Production from Maria Phase 2 has started and is contributing to increased recovery from the central part of the Garn Formation, which was previously not drained by existing wells. In addition, two potential infill targets have been identified and matured, with planned drilling in 2027–2028.
