Brønnhistorie
GeneralWell 16/4-4 was drilled on the south-west part of the Utsira High in the Norwegian North Sea. The objective of the well was to prove hydrocarbons in the Ty/Heimdal Paleocene turbidite sandstones in the Biotitt prospect. It was important to acquire sufficient data to understand the reservoir characteristics and fluid distribution.Operations and resultsWildcat well 16/4-4 was spudded with the jack-up installation West Epsilon on 28 December 2006 and drilled to TD at 2409 m at the top of the Late Cretaceous Tor Formation. The well was drilled with seawater/bentonite/polymer mud from down to 1213 m, and with KCl/PAC/GEM GP mud from 1226 m to TD. No shallow gas was observed.The well penetrated rocks of Quaternary, Tertiary and Cretaceous age. The Ty reservoir section was encountered at 2271 m, 12 m deeper than prognosed. It was 79 m thick and consisted of fine to medium sandstone with claystone and limestone. The Heimdal Formation was not present in the well. The pressure tests indicated an approximately 7 m thick gas/condensate column in the upper part of the Ty Formation. There were no hydrocarbon indications elsewhere in the well.One core was cut from 2275 m to 2302 m in the Ty Formation. Twenty excellent MDT pressure tests were acquired together with MDT water samples at 2284.9 m and MDT condensate samples at 2272.5 m.The well was permanently abandoned on 23 March 2003 as a gas/condensate discovery.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]pdf0.23
