Brønnhistorie
GeneralWell 16/2-13 A is a geological side track to well 16/2-13 S on the Johan Sverdrup discovery on the Utsira High in the North Sea, 6.7 km northeast of well 16/2-8 and 2.4 km north-east of well 16/2-6. The objective of the side track was to calibrate the depth model in a position far enough away from 16/2-13 S to provide significant information for depth conversion; to investigate if FWL in 16/2-10 is present in area across the fault close to 16/2-13 S and; to map lateral thickness and quality variations in the Jurassic sequence.Operations and resultsWell 16/2-13 A was kicked off at 735 m in 16/2-13 S on 30 August 2012. The semi-submersible installation Transocean drilled the well to TD at 2776 m (2101.7 m TVD) in indeterminate pre-Rotliegend Group rock. The sidetrack was drilled with Enviromul OBM.The reservoir was encountered at 2596.06 (1926 m TVD) about 1250 metres north of well 16/2-13 S and slightly shallower than prognosis. It consisted of a 26.5 m thick Intra-Draupne, Intra-Heather and Hugin sandstone package, similar as in 16/2-13 S. The oil column in the sidetrack was 12 m and the oil water contact was established at 1949 m TVD (1925 m TVD MSL).Four cores were cut from 2587.3 m in Draupne Formation shales to 2669.0 m in Pre-Rotliegendes rock. The core to log shift for all four cores is -1.5 m. The core recovery was 100%. RCX wire line fluid samples were taken at 2596.7 m (oil), 2607.5 m (oil), 2608.5 m (oil and water), 2610.7 m (water), and 2615.0 m (water).The well was permanently abandoned on 29 September 2012 as an oil appraisal.TestingNo drill stem test was performed. -

Trykkplott
Trykkplott Porertrykksdataene kommer fra logging i brønnen hvis ingen annen kilde er oppgitt. I noen brønner der trykk ikke er logget, er det brukt informasjon fra formasjonstester eller brønnspark. Trykkdataene er rapportert inn til Oljedirektoratet og videre prosessert og kvalitetssikret av IHS Markit.Trykkplott Dokument navnDokument formatDokumentstørrelse [MB]pdf0.22
