The redevelopment project involves the installation of two new subsea templates that will be tied back into the Ekofisk Complex to tap into an estimated 63 MMboe of recoverable reserves.
ConocoPhillips plans to drill seven production wells in the Tor formation along with a pilot well to evaluate the long-term productivity in the Ekofisk formation.
First production from the re-developed Tor field is targeted to be achieved towards the end of 2020.
The Tor field was discovered in 1970 and was producing for 37 years until the production was shut down in 2015 when the installation reached the end of its lifetime. At shutdown, just 20% of the resources in place had been produced.
The field is located in licenses PL018 and PL006 in blocks 2/4 and 2/5, about 13 km northeast of the Ekofisk field.
Tor produced oil and gas from fractured chalk of Late Cretaceous age in the Tor Fm and of early Paleocene age in the Ekofisk Fm. There are significant remaining resources in both formations.
The licenses are operated by ConocoPhillips Norge with a stake of 30.66% and is partnered by Total E&P Norge (48.20%), Vår Energi (10.82%), Equinor Energy (6.64%) and Petoro (3.69%).
