NORSOK Standard D-010

Rev 3, August 2004

ForewordThe NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. Furthermore, NORSOK standards are as far as possible intended to replace oil company specifications and serve as references in the authorities regulations. The NORSOK standards are normally based on recognised international standards, adding the provisions deemed necessary to fill the broad needs of the Norwegian petroleum industry. Where relevant NORSOK standards will be used to provide the Norwegian industry input to the international standardisation process. Subject to development and publication of international standards, the relevant NORSOK standard will be withdrawn. The NORSOK standards are developed according to the consensus principle generally applicable standards work and according to established procedures defined in NORSOK A-001. The NORSOK standards are prepared and published with support by The Norwegian Oil Industry Association (OLF) and Federation of Norwegian Manufacturing Industries (TBL). NORSOK standards are administered and published by Standards Norway.

IntroductionThis revision was initiated to make this NORSOK standard compliant with changes in legislation and adapted to evolving and new technology. In this revision, the user will find that the standard has been completely reorganised and that the content and structure is different than the previous revision. The intention has been to make it easier to find information and provide flexibility to updating or revising this NORSOK standard in the future without altering its structure. Consequently, the changes from the previous revision are not marked. The following main changes are implemented in this revision: The focus of this NORSOK standard is well integrity, which is the application of technical, operational and organizational solutions to reduce the risk of uncontrolled release of formation fluids throughout the entire life cycle of the well and of course safety aspects. Recommendations for best practices are not dominant. This led to renaming this NORSOK standard to "Well integrity in drilling and well operations". The descriptions are mostly insensitive to type of well and type of installation. Clear and concise requirements (shall) and guidelines (should) have been applied to stress their importance and to differentiate the process of handling deviations from these. Overlapping or duplication of text or topics in other standards has been minimized. Well barrier related terminology with definitions has been established in lack of apparent international standard definitions. Pre-defined WBSs for most common situations have been included.
