PRODUCTION FROM THE FIELD

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 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.

Reservoir

Maria produces oil and gas from the Middle Jurassic Garn Formation. The formation is 90-100 metres thick and consists of massive sandstone with shale layers. The reservoir quality is best in the southern part of the deposit. The underlying Tilje and Ile Formations are aquiferous. The reservoir lies at a depth of 3,800 metres.

Recovery

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 has been lower than forecasted since start-up, due to limited reservoir communication and pressure support from the water injectors. Based on the production experience, total recovery from the field is expected to be lower than the PDO estimates. Work is ongoing to increase production, and drilling of more wells is being evaluated to increase recovery from the field.
