On 22 January 2018 Lundin announced that it has increased the ultimate recoverable reserves at Edvard Grieg by 51 MMboe (since the end of 2016) to 274 MMboe and that this represents a 47% increase compared with the PDO. Good drilling results and production performance have indicated that the oil in place volumes are higher than originally calculated and that more of the oil is in the better quality sandstone part of the reservoir (with less in the poorer quality conglomerate zone).  In early 2017 Lundin drilled Edvard Grieg appraisal well 16/1-27 on the southwestern flank of the field. It proved a 15 m gross oil column in a 94 m thick Cretaceous and Triassic / Jurassic sandstone, considerably thicker than the pre-drill estimates of 38 m, with excellent reservoir quality. Top reservoir was penetrated deeper than expected and the OWC was confirmed at 1,948 m, 9 m deeper than prognosed for this part of the field. Results indicated a resource upside of between 10 and 30 MMboe for this part of the field and provided information which will help with the placement of future production and water injection wells. During 2016 Lundin announced a reserves upgrade from 186 MMboe (in the PDO) to 223 MMboe (including the adjacent Tellus field) following the success of appraisal well 16/1-23 S, drilled on the southeastern part of the field in 2015, and two water injection wells drilled in 2016 which proved more oil in the western flank. Lundin achieved first production from Edvard Grieg on 28 November 2015. The field has been developed using a processing platform with oil piped to Grane for onward export to Sture and gas exported to the UK through the SAGE pipeline. Plateau production was reached in December 2016 at 100,000 boe/d and the platform processes 160,000 boe/d with production from neighbouring Ivar Aasen.  Interest in Edvard Grieg is held by Lundin Norway AS (65% + operator), OMV (Norge) AS (20%) and Wintershall Norge AS (15%).
