Wellbore history
GeneralWell 34/7-32 was drilled on the Xenon structure on Tampen Spur ca 2 km west of the Snorre Field in the North Sea. The objective was to test the hydrocarbon potential in the Middle Jurassic Brent Group. The well was planned and drilled as a "smart well" i.e. with a reduced data acquisition programme if dry.Operations and resultsWildcat well 34/7-32 was spudded with the semi-submersible installation on 9 October 2001 and drilled to TD at 2651 m in Middle Jurassic rocks of the Drake Formation. A 17 1/2" pilot hole was drilled from 384 m to 700 m to check for shallow gas. No shallow gas was observed. The well was drilled with sea water and hi-vis pills down to 1385 m and with Versavert oil based mud from 1385 m to TD. No significant problem was encountered in the operations. Total rig time from spud to P&A was 20 days, including two days wait-on-weather.The sandstones in the Brent Group proved to be water bearing, with a water gradient of 1.00 g/cm3. No shows were observed.No cores were cut. Wire line logging consisted of one run (MDT-GR-ECRD) from 2616 m to 2538 m. Seven pressure points were acquired, no fluid sample was taken.The well was permanently abandoned on 27 October 2001 as a dry well.TestingNo drill stem test was performed. -

Pressure plots
Pressure plots The pore pressure data is sourced from well logs if no other source is specified. In some wells where pore pressure logs do not exist, information from Drill stem tests and kicks have been used. The data has been reported to the NPD, and further processed and quality controlled by IHS Markit.Pressure plots Document nameDocument formatDocument size [MB]pdf0.22
