Lundin Norway has efficiently accomplished the PDO improvement drilling programme at its operated Edvard Grieg discipline on the Utsira High within the Norwegian North Sea. A major reserves improve and extension of the manufacturing plateau have been made for the reason that PDO with further useful resource potential recognized within the space.
The Edvard Grieg discipline in PL338 began manufacturing in late 2015. The drilling programme, consisting of 14 improvement wells, has efficiently been accomplished beneath price range by the Rowan Viking jack-up drilling rig, which is now being demobilised.
Overall reservoir outcomes from the event drilling have exceeded the pre-drill expectations. Combined with a robust reservoir efficiency, that has seen no materials water manufacturing thus far, these constructive outcomes have led to a 47 p.c improve of the very best estimate gross final restoration for the Edvard Grieg discipline for the reason that PDO. In addition, additional contingent assets are recognized related to infill drilling alternatives.
The reserves improve has led to the sphere manufacturing plateau being prolonged from the PDO by two years to finish 2019. An infill improvement drilling programme is being deliberate for 2020 which has the potential to additional prolong the manufacturing plateau. A 4D seismic survey is being acquired over the sphere in 2018 to refine the infill effectively targets.
Current gross manufacturing from Edvard Grieg is roughly 95 Mboepd, which displays the amenities capability allocation with the Ivar Aasen discipline. The capability of the Edvard Grieg manufacturing wells is presently greater than double the obtainable amenities capability, which supplies flexibility to optimally handle the reservoir. The amenities proceed to carry out forward of steerage with a manufacturing effectivity of 97 p.c yr thus far. Total gross manufacturing from Edvard Grieg from first oil to finish of the primary quarter 2018 amounted to 74 MMboe.
The operated oil discoveries Luno II in PL359 and Rolvsnes in PL338C are being matured as subsea tie-back improvement alternatives to the Edvard Grieg amenities. The latest Lille Prinsen oil discovery in PL167 can also be a attainable space tie-back alternative. Additionally, additional space prospectivity is being matured for drilling in 2019. In complete, there may be potential to double the assets to be produced by means of the Edvard Grieg amenities. (Source and picture: Lundin/Lundin personnel on Edvard Grieg platform)
