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, formerly only three wells.

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 MMSm3 oe oil, 0.4 MMSm3 oe Gas, 0.3 MMSm3 oe NGL.
