Development

Oda is a field in the southern part of the Norwegian sector in the North Sea, 14 kilometres east of the Ula field. The water depth is 65 metres. Oda was discovered in 2011, and the plan for development and operation (PDO) was approved in 2017. Oda is developed with one subsea template with two production wells and one injection well tied-back to the Ula field. The production started in 2019.

Reservoir

Oda produces oil from sandstone of Late Jurassic age. The main reservoir is in the Ula Formation at a depth of 2900 metres. The reservoir is steeply dipping and has good quality.

Recovery strategy

The field is produced by pressure support from water injection.

Transport

The well stream is transported by pipeline to the Ula field for processing. The oil is exported to Ekofisk and then onward in Norpipe to the Teesside terminal in the UK. The gas is sold to Ula for injection into the reservoir to increase oil recovery from the Ula field.

Status

Drilling of the production wells has shown that the reservoir is more complex and smaller than anticipated. Consequently, the estimated recoverable volumes have been decreased. In 2023, the production has steadily declined with increasing water cut.
