Norway proposes revision to NORSOK well integrity guidelines

Standards Norway, one of three standardization bodies in Norway, has released Revision 4 of the NORSOK Standard D-010, Well Integrity in Drilling and Well Operations. The proposed revision includes more than 450 changes intended to improve the standard, most of which address recommendations from Norsk Olje og Gas’ Macondo report. All well barrier schematics have been redrawn, mainly to include in-situ formation as part of the well barrier envelope.

Details of the revisions, as well as instructions on how to submit comments on the proposal, are available here.

The comment period ends on 15 February 2013.  The goal is to release the revised standard in June 2013.
