About this Micro Virtual Instructor Led Training (VILT)
Well Integrity is concerned with constructing a well with a system of physical barriers to prevent the unplanned movement of fluids within a well and preventing unplanned release into the environment. In the subsurface part of a well, the intent is to prevent unplanned flow between formations and especially the flow of hydrocarbons into water bearing zones. At the surface (land, seabed or platform), containment of the well bore fluids is normally achieved with valves and manifolds, typically comprising a wellhead and Xmas Tree. Following this Micro VILT, participants will understand why an Effective Well Integrity Management System is required to ensure that Well Barriers are designed and constructed with a number of elements selected to meet the required performance criteria. These elements are often the casing, cementing, completion components, wellhead and Xmas Tree. For a Barrier to be considered effective, it and its elements need to be tested and verified both upon installation and at intervals during the well’s lifetime. Monitoring and management of well barriers during the life of a well is referred to as Well Integrity Management Various Bespoke Software Systems exist as well as some IOC In-House systems. Participants will be shown some real live examples as well as sample reports that the various government regulators and industry bodies require to be submitted on a regular basis. The key to successful Well Integrity Management includes:- Organisational Competency
- Developing proactive rather than reactive well integrity management
- Designing for the Life Cycle - Embedding well integrity in the equipment design
- Solid well construction practices and well life cycle management
- Management commitment
- Design & Construction
- Understanding the Barrier Envelopes
- Verifying Barriers & Acceptance Criteria
- Planned Preventative Maintenance & Testing
- Well Failure Model
- Management of Change
- KPIs, League tables, Regulator requirements
- Management of Data
- Understanding Loss of Containment Planning
- Regulation based discussion.
- Group exercises.
- Slide presentation.
- The break out group discussion was very helpful.
- Reasons why WIMS is needed, elements of WIMS, and typical gaps of them.
