About the field

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Development: Tor is a field in the southern part of the Norwegian sector in the North Sea, 13 kilometres northeast of the Ekofisk field. The water depth is 70 metres. Tor was discovered in 1970, and the plan for development and operation (PDO) was approved in 1973. The field started production in 1978 and was shut down in 2015. A new PDO for the redevelopment of Tor was approved in 2019. The development includes two subsea templates with eight horizontal production wells, tied-back to the Ekofisk Centre. The production started again in 2020.
Reservoir: The reservoir contains oil and gas in chalk of Late Cretaceous age in the Tor Formation and of early Paleocene age in the Ekofisk Formation. The Ekofisk Formation is tighter and less fractured than the Tor Formation. There are significant remaining resources in both formations. The reservoir depth is 3200 metres.
Recovery strategy: The field is produced by natural pressure depletion.
Transport: The well stream is transported by pipeline to the processing facility at the Ekofisk Centre and further to Teesside in the UK and Emden in Germany.
Status: Several of the wells have experienced higher water cut than anticipated. The original facility was removed in 2024.
