Well integrityDefined by NORSOK as application of technical, operational and organizational solutions to reduce the risk of uncontrolled release of formation fluids throughout the life cycle of a wellVarious facets to well integrity including:Accountability and responsibility, well operating processesWell service processesAnnulus IntegrityWellhead integrity and testing

Well integrity

Happen again?

DWH was a catastrophic facility integrity failure (CFIF)This could happen any time anywhere, butTheoretically less likely due to method of regulation Individual installation assessmentProblems facing all activitiesDeeper waterDo we really know the issues?Regulation keeping upAgeing installationsGannet Alpha in August 2011North Sea

Regulatory response to MontaraWhy is well integrity important? What prevents groundwater damage or well blowoutNo single HF caused damage is Loss of well control or failure of integrity of the well..Dont want wells to leak when wells leak need environmental response
