Te fundamenty of Well Integraty

Well integration is defined of formation fluids the applicatioon of technical, operational, and organisationol solutions to prevent the uncontrolled release of formation fluids and gases the entire life cycle of a well. This includes the design, construction, operation, and dependonment fazes. A well 's integraty is mainmaintained the thridge a serie of controveriers - both physical and hydraulic - that isolate the wellbore from the oxiconding geological formations.

Barriers are typically categorized as primary (e.g., tubing, packer, downhole safety valve) and secondary (e.g., casing, cement, wellhead, BOP).
