Nyob rau ntawm Gudrun teb nyob rau sab qaum teb Hiav Txwv, Equinor thiab nws cov neeg koom tes tau pom cov roj thiab roj nyob rau hauv wildcat qhov dej 15/3-13 S thiab 15/3-13 A.
Cov no yog 13th thiab 14th kev tshawb nrhiav qhov dej hauv cov ntawv tso cai tsim khoom 025. Lub Deepsea Stavanger rig tau siv rau qhov drilling. Qhov kev tshawb pom qhov loj yog kwv yees li ntawm 0.1 thiab 1.2 lab tus qauv cubic meters (Sm3) ntawm cov roj rov qab sib npaug hauv Draupne Formation thiab nruab nrab ntawm 0.4 thiab 1.3 lab Sm3 hauv Hugin Tsim, raws li kev kwv yees ua ntej. Cov ntawv tso cai yuav ntsuas qhov txiaj ntsig zoo hauv cov ntsiab lus ntawm kev cia siab hauv zos. Lub hom phiaj tseem ceeb ntawm qhov kev tshawb nrhiav qhov dej yog nrhiav cov roj av hauv nruab nrab Jurassic reservoir pob zeb hauv Hugin Formation thiab Lig Jurassic reservoir pob zeb hauv intra-Draupne Formation. Nrhiav ib lub reservoir hauv Rødby Formation's Early Cretaceous reservoir pob zeb yog lub hom phiaj thib ob tshawb nrhiav.
Nyob rau hauv intra-Draupne Formation, Zoo 15/3-13 S tuaj rau hauv nyias strata ntawm sandstone uas muaj roj. Tsis muaj kev sib cuag ntawm dej thiab roj. Lub qhov dej pom 92 meters ntawm sandstone nrog subpar reservoir yam ntxwv hauv Hugin Tsim. Muaj ob qhov piv txwv ntawm cov pa roj, txhua qhov muaj qhov tuab ntawm 8 thiab 7 meters. Tsis muaj kev sib cuag ntawm cov roj thiab dej. Lub hom phiaj ntawm qhov drilling 15/3-13 A, ib sab, yog los txhais qhov kev tshawb pom. Lub Peb Hlis 15, 2013 Intermittent sandstone layers with moderate reservoir quality made about 13 meters of the 85-meter thick oil discovered in the intra-Draupne Formation. Nws tau tsim tias muaj kev sib tshuam roj / dej 4328 meters hauv qab dej hiav txwv. Hauv Hugin Tsim, 15/3-13 Ib qho kuj tau nthuav tawm kwv yees li 100 metres ntawm sandstone nrog subpar reservoir yam ntxwv. Tsis muaj pov thawj ntawm kev sib cuag roj / dej tau pom, thiab tag nrho lub sijhawm yog aquiferous. Tsis muaj lub pas dej tau pom nyob rau hauv lub hom phiaj tshawb nrhiav thib ob, Rødby Tsim nyob rau hauv qis Cretaceous.
Cov qhov dej tsis tau tsim-kuaj, tab sis cov ntaub ntawv nthuav dav thiab kev kuaj tau ua tiav.
Zoo 15/3-13 S tau drilled rau qhov ntsuas ntsuas thiab ntsug qhov tob ntawm 4826 meters thiab 4740 meters hauv qab dej hiav txwv. Zoo 15/3-13 A tau drilled rau qhov ntsuas ntsuas thiab ntsug qhov tob ntawm 4900 meters thiab 4814 meters hauv qab dej hiav txwv. Ob lub qhov dej tau raug txiav tawm hauv Sleipner Tsim nyob rau hauv Middle Jurassic. Qhov tob ntawm dej yog 110 meters, thiab cov qhov dej tau txuas mus tas li thiab tso tseg.
