Lundin Petroleum has efficiently accomplished the appraisal properly 16/1-28S and manufacturing check on the Rolvsnes discovery within the PL338C on the Utsira High within the Norwegian North Sea.
The appraisal properly is positioned roughly three km from the Lundin Norway operated Edvard Grieg platform and is the third properly on the Rolvsnes oil discovery. The fundamental goal was to substantiate business charges from a horizontal properly drilled in fractured and weathered basement reservoirs, just like these at the moment producing within the northern space of the Edvard Grieg discipline.
The properly was drilled horizontally within the reservoir interval and encountered 2,500 metres of fractured and weathered basement. Extensive information acquisition and sampling have been carried out within the reservoir, together with a 10 day manufacturing check with manufacturing logging and backside gap fluid sampling. A most constrained manufacturing charge of seven,000 bopd was achieved, whereas the 5 day fundamental move interval was held at a manufacturing charge of four,200 bopd. The check outcomes present good reservoir productiveness and connection to a big oil quantity that advantages from aquifer strain assist, that are constructive elements in the direction of demonstrating business restoration at Rolvsnes.
Following these constructive properly outcomes, the gross useful resource vary for the Rolvsnes discovery has been elevated to between 14 and 78 MMboe from the earlier vary of between three to 16 MMboe. The long-term manufacturing behaviour from this reservoir kind must be understood higher and choices are being assessed to conduct an prolonged properly check of the horizontal appraisal properly. Rolvsnes is taken into account a possible tie-back improvement to Edvard Grieg. The properly was drilled by the COSL Innovator semi-submersible drilling rig and following completion of properly suspension operations the rig went off rent.
