Lundin decides against standalone development for Barents Sea duo

Swedish oil and gas company Lundin Petroleum has opted against a standalone development for the Alta and nearby Gohta discoveries, located in the southern Barents Sea, in favor of a subsea tie-back to a host development in the area.

In an update on Monday, Lundin said that the contingent resource estimate for the Alta discovery had been adjusted downwards based on evaluation of the high specification 3D seismic survey (Topseis) acquired over the area, combined with the extensive data and analysis from the well drilled for the extended well test conducted in 2018.

Therefore, a standalone development of the Alta and nearby Gohta discoveries is no longer considered to be commercial, and a subsea tie-back development to either Johan Castberg or another future host development in the area is considered the most viable option, Lundin said.

Lundin completed an appraisal well and extended production test at the Alta discovery in September 2018. The main objectives of the appraisal well and extended production test was to prove sustainable production rates and reduce the uncertainty around the recovery mechanism in the Permian-Triassic karstified and fractured carbonate reservoirs to provide the basis to progress development studies.

The semi-submersible drilling rig Leiv Eiriksson was used for the drilling and testing at Alta. The well was tested through the rig and the produced volumes were flowed via a flexible flowline to the Teekay Scott Spirit tanker.

The Gohta appraisal well was completed May 2017 and it was also drilled using the Leiv Eiriksson semi-submersible rig.

Lundin added it was drilling several large prospects in the Loppa High area in 2020, which if successful could change the dynamic of commercial options for this area.
