About this Virtual Instructor Led Training (VILT)
This Virtual Instructor Led Training (VILT) is an overview of well design, construction, verification, operation, intervention, optimisation and eventual P&A.
Session 1 - Deepwater Completion Overview
Introduction and the basics: A brief introduction to what the course will cover and the methods and media that will be utilised over the next 8 sessions.
- Introduction to the completion process focusing on the Completion Basis of Design (BOD), the methods & tools (Prosper/Modelling) how to design, what to design, flow-rate.
- An overview of the field life cycle: water cut, declining reservoir pressures, hazards (scale, corrosive fluids). Conceptual Designs will include TSA.
- Overview of subsea development type (satellites, daisy chain, integrated template, cluster), including videos.
Session 2 - Lower Completion (sometimes referred to as the Sandface Completion)
- When considering the completion Fluid System it can be divided into two main groups:
- Well Bore Clean Out
- Suitable Fluid for Life of Well Considerations
- Sand Control Methods
- Selection of Optimum Equipment
- Formation Damage – How to Minimise – How to repair
- Connecting to the Reservoir (Frac, Perforation, Stimulation)
Session 3 - Upper Completion
- Overview of the various Packers & Setting mechanisms, Downhole Flow Devices (Smart Wells), Downhole Monitoring Equipment (PDHG, DTS)
- Chemical Injection (for Flow Assurance v Corrosion Protection), Subsurface Safety Valves Videos on Packers & DHSV
- Explanation of various, wellhead, XMT and BOP interfaces
Session 4 - Upper Completion continuation
- Xmas Trees & Wellheads (Horizontal v Vertical, Pros & Cons)
- Artificial Lift
Session 5 - Subsurface: Upper Completion
- Complete the Well On Paper (CWOP)
- Barrier Philosophy (Installation, Verification, Phases)
- Interventions During Well Construction – Consider Contingencies , Interventions Post Construction, Non-Intrusive Interventions (Chemical/Acid treatments)
Session 6 - Operating & Producing a Well
- Operating & Producing the well, Unloading the well, Wellbore Clean Up, Temporary Well Test Package
- Flow Assurance & Well Performance, Hazards (Scale, Asphaltenes, Hydrates) and understanding the potential problems and indications
- Well Integrity & Reservoir Management, understanding TAP & SCP and suitable mitigations, as well as maximising production and Ultimate Recovery
Session 7 - Subsea Artificial Lift (boosting), Well Kickoff & General Deepwater Risks & Timings
- General overview of Subsea artificial lift/boosting (riser base gas lift v MPP)
- Well Unloading processes, including shutdowns & restarts of production and the key focus areas.
- Additional risks associated with Deepwater Wells such as Equipment Failures, Reservoir Issues as well as an overview of the main timing differences between Platform & Subsea Wells.
Session 8 - Overview of P&A
- Considerations for P&A from Initial Design
- Current Legislation and interpretation of the same
- Overview of various methods of Subsea Abandonments
Session 9 - Team Exercise, Course Summary and Wrap up
Best Feature of the VILT:
- The introduction, the completion and the production sessions.
- Recording and stimulation exercises.
- The interactive experience between participants and trainer.
- Relevant experience and case histories for deep water application.
- Centralized file sharing. All discussion point and material recorded can be referred back anytime.
- Short breaks in between sessions
- Group activities
