32/4-2

General

Well 32/4-2 was drilled to test the Gladsheim prospect on the Horda Platform in the Stord Basin Area. The prospect is located approximately 25 km east of Troll East and 30 km from shore. The primary objective was to prove oil migration into the Sognefjord Formation and establish the corresponding fluid contacts. Secondary objective was to test the gas potential in Mid- and Lower Jurassic Brent Group, Johansen Formation and Statfjord Group. A tertiary objective was to verify Late Jurassic shales sealing capacity and acquire data to confirm CO2 storage potential and to extend the well into the Lunde Formation for this reason

Operations and results

Wildcat well 32/4-2 was spudded with the semi-submersible installation West Hercules on 9 September 2019 and drilled vertically with two hole sections: 32”x42” and 17 ½’’. These sections were drilled with seawater and returns to seabed. After running the 20 x 13 3/8” casing, gas bubbles were observed flowing from LPWHH circulation ports. The shallow hazard evaluation had given a shallow gas Class 0, so shallow gas was not expected at the well location. Neither was shallow water flow. Gas samples were taken. A 13 3/8" casing cement bond log and an acoustic log were performed on wireline from respectively 1130 m to seabed, and 767 m to 320 m. The BOP was run and pressure tested to 183 bar for 60 minutes against the 13 3/8" casing. Mud/water forming craters on the seabed was observed around the wellhead. The

decision was made to pull the BOP and the riser and to abort further operations on this well. TD was thus set at 1185 m in the Late Jurassic Draupne Formation.

Due to the unexpected shallow gas and water flow the well was te
