and gas was achieved in 1979. The field was shut down in 2015 and, following the completion of new wells, started up again in 2020.

The field

The characteristics of the Tor field reservoir are as follows.

Owners and operator

The current (2024) owners of the Tor field are: The field is operated by ConocoPhillips Skandinavia AS.

Infrastructure

The field has been developed with an offshore platform facility, designated Tor E.

Production

Production started in July 1978. The production profile was as follows. Units are million standard cubic metres oil equivalent.

Developments

Oil was initially produced by pressure reduction. From 1992, water flood was introduced. Export from Tor was initially routed by two pipelines to Ekofisk R. Subsequently, in 1998, fluids were routed to Ekofisk 2/4 J. In 1989, a gas-lift module was added, this allowed eight wells to use gas lift, compared to only three wells formerly. In 2019, two subsea templates with eight horizontal production wells were tied back to Ekofisk centre. The remaining recoverable reserves in 2023 were 4.3 million standard cubic meter oil equivalent oil, 0.4 million m³ oe Gas, 0.3 million m³ oe NGL.
