Course Overview
PetroSync is proud to present “Trouble-Free Well Integrity Management” with the global leading expert, Rein Maatjes. Addressing vital issues in well integrity model, active management, well surveillance, risk mitigation, and real life lessons from offshore Africa, the Middle East, East Russia and the Far East regions.
“Sustained Offshore Wellbore Integrity“ (Day 1 -3) program will provide the essentials of both theory and practice in the field of production engineering. Evaluation and improvement on well deliverability will be addressed in details.
"Proactive Well Integrity Management" (Day 4-5) program is intended to address the science and management strategies related to maintaining well integrity throughout life cycle.
These programs will also provide in-depth interdisciplinary knowledge as applied to reservoir & production engineering through discussion of actual up-to-date field
experiences and case studies.
This program is designed for professionals of the following disciplines, who are involved in the design, construction, operation and services of wells:
• Production Technology
• Well Integrity Engineering
• Asset Management
• Production Maintenance & Operations
• Well Intervention
• Well Services
• Drilling Engineering
• Safety Engineering
Benefits:
- Understand well integrity management and its relation with CAPEX, OPEX
- Learn Preventative Maintenance and Benchmark processes for surface, subsurface, external and internal maintenance
- Identify and Diagnose mechanical integrity of well with latest technology:
- Fiber Optics, PLT, CFBM, Multi Finger Caliper, Non-intervention Investigation
- Be informed on catastrophic failure of well integrity : external and internal influences
- Monitor for and Understand mechanical integrity problems preventing potential production rates
- Consequences of loss of integrity of one well to its surrounding wells and potential financial exposure
- Know the underground blowout factors of older well and proper well abandonment
- Brainstorm FMEA, Active Management Model and Overcoming barriers with proven methodologies
- Benchmark and Discuss how to build an organization with sufficient well integrity competence and capability
Definition of the various components of the well and showing the integrity barriers.
Capex and Opex affects Well Integrity Management
How each has an influencs on Well Integrity and why it needs managing
Preventive maintenance reduces Operating cost and optimizes production
• [CASE STUDY]: Unit Operating cost goes down after spending WHM cost. Why?
• Why spending money could reduce production operation cost
• Surface equipment, trees, wellheads etc
• Subsurface maintenance
• [CASE STUDY]: High frequent intervention results in wear of tree-cap threads. This needs management system.
• External well integrity maintenance
• [CASE STUDY]: Change of external maintenance speed and cost as result of different method
• Internal well integrity maintenance.
• Internal integrity maintenance secures and maximizes production volumes.
• Leaking Gaslift valve, reduces optimum lift of oil.
• PLT Logging Techniques.
• Securing internal integrity, reservoir reconciliation, leak detection etc.
• Caged Full-bore Flow meter (6 arm CFBM) for horizontal applications
• Multi Finger Caliper.
• Establishes tubing base line wall thickness and corrosion over life cycle of the well.
• Non-intervention less investigations like Pressure testing.
• Cheap methods to confirm internal integrity.
• Pony tail leak detection; cheap fit for purpose.
• Fiber Optic internal integrity management.
• Low cost alternative to CTU on horizontal wells.
• Detects leaks.
• Production profile
Wrap-up of the day
• Grouting of conductor.
• Mon pod design
• Open riser at bottom.
• [CASE STUDY]: Catastrophic failure of well because of External corrosion
• [GROUP EXERCISE]:
• Breakout in groups, and find solution to mitigate absence of grouting of risers on platforms.
• Prevent corrosion in open risers.
• Calculation of corrosion and point of failure.
• Internal corrosion and subsequent integrity failure .
• Risk to the completion string from internal sources.
• [CASE STUDY]: North Sea water injector failure.
• [CASE STUDY]: North Sea hanger stress cracking failure.
• [QUIZ]: How long does it take before casing is corroded in above case?
• Understanding of barriers.
• Show different types of wells.
• Sand removal.
• Wax Milling
• Scale removal.
• Leaking gaslift valves, its remedy and solution
• Blocking of unwanted water production
Consequences of loss of control during drilling on platform
• [CASE STUDY]: Offshore South China Sea well
• Show photos and video clip.
• [GROUP EXERCISE]: When opening-up the wells on the platform, bubbles were seen on Seabed.
What could be the matter.
• Stress value of WIMS system in this case and testing all
SCSSV’s and checking wellheads.
• [CASE STUDY]: Omitting one string of casing in a well.
• Cost saving.
• Impact on the environment.
• Mitigating measures taken.
• [CASE STUDY]: Well cellar blowing-out mud. Show aerial
photos.
• [GROUP EXERCISE]: Find yourself in the Emergency Control
Room and analyze what is happening and how to act to support
these findings?
• [CASE STUDY]: Drilled well knowingly not to design
Specifications.
• No cement to surface.
• Accepted, as remediation was expensive.
• Consequences could have been very high.
• One well had very high cost (GOM)
• As result of older wells.
• Do not take this task lightly
• [EXERCISE]: How would a good organization look like to manage well Integrity in your organization? Show lines of communication.
It starts off with input in the FDP.
• Input in the design of the well.
• Life cycle maintenance by Maintaining, monitoring and
planning of the activities.
• How should a cradle to grave Well Management team look like?
• Who would be ideally suited to be life cycle custodian?
• Remember an Organization needs independent Integrity Authority (accountable of integrity and not for prod targets)
• Barrier definition.
• Explain barriers.
• Explain how testing is done
• Referring to the barriers discussed above, make a plan to test and verify the barriers.
• Consider cost
• Resources.
• Accessibility to platform etc.
• Discuss testing methods of the barriers in the well
DAY 5
• Show barriers, function and its severity in case of failure.
• Discuss testing and managing the data.
• Monitoring plan.
• Provide systems and procedures, which ensure that the integrity of the well is assured
• Ensure that the well is maintained with reference to appropriate procedures and specifications
• Ensure that the risks of operating the well are as low as reasonably practicable
• Basis for the development of asset-specific well maintenance and integrity standards, policies, procedures and performance targets
• Discuss actual document and what should be in a good manual.
• Life cycle risk management.
• [REAL CASE STUDY]: Well Integrity Management System (WIMS) and alternatives (fit for purpose systems)
• Understanding of Lowest unit cost, as opposed to cheapest.
• Competent staff.
• The right Contracts.
• Spare parts.
