Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 31/2-17 BR is a re-entry of well 31/2-17 B. The objective of the re-entry was plugging and permanent abandonment.

Operations and results

Well 31/2-17 B was re-entered (31/2-17 BR) with the semi-submersible installation West Delta on 14 February 1993. Operations took 11 days, which included 6 days down-time due to wait on weather and problems with connecting Guide base and BOP to old well head.

The well was plugged and permanently abandoned on 24 February 1993 as a gas and oil appraisal.
