Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Wells 34/8-13 A and 34/8-13 S were drilled in the Tampen Spur area of the North Sea. The objective of the wells was to the test the hydrocarbon potential in the Titan prospect. The prospect is located east of the Visund N2 Brent segment as part of the Visund N2 East Flank degradation complex, and contains two slide blocks, B and C. The primary objective of the 34/8-13A was to test the hydrocarbon potential of slide block B in the Titan prospect while the sidetrack 34/8-13 S, was drilled to test slide block C. For technical reasons the naming of these wells is reversed compared to usual practice: the A well is the main well while the S well is the geological sidetrack.

Operations and results

A 9 7/8" pilot hole, well 34/8 -U-1, was drilled from sea-bed to 725 m MD to evaluate for shallow gas. Based on MWD/LWD and ROV no indications of shallow gas were observed.

Wildcat well 34/8-13 A was spudded with a 36" hole opener with the semi-submersible installation on Scarabeo 5 and drilled to TD at 3852 m (3132.7 m TVD) in Late Triassic sediments of the Statfjord Formation. No indications of shallow gas were observed when drilling the 36" and 26" hole in well 34/8-13 A. The well was drilled with seawater and hi-vis sweeps down to 1324 m, and with XP-07 oil based mud from 1324 m to TD.

The well penetrated rocks of Quaternary, Tertiary, Cretaceous and Jurassic age. The Viking Group, Draupne Formation was encountered at 3349 m (2869.8 m TVD), and an intra Draupne Formation sandstone was encountered at 3386 m (2887.7 m TVD). Oil was discovered in the Intra-Draupne sandstone and down into degraded Brent sandstone. An oil leg of 19 m TVD was proven in the well positio
