Managing Well Integrity through Design, Verification and Repairs with Rein Maatjes

1st September 2015


The Master Class combines several engineering disciplines involved in the design, construction, operation and maintenance of wells and their interaction on assuring well integrity. It is advancement on the Well Integrity Management Class, which teaches the principles, the Roles and Responsibilities and management systems in an organization.

It illustrates the large extent and involvement of various disciplines in the organization and its effects on well integrity.  It aims to create understanding of the often-conflicting targets within the disciplines in achieving this.

The knowledge and skills to design and make critical decisions on observed WI envelope breaches throughout well life cycle is vital, not only for WIM purpose as well as to increase ultimate recovery of the reservoir. I.e. maximum cash flow generation.

The ultimate objective is to optimize productivity at lowest Unit Operating Cost (UOC) and to maintain mechanical integrity throughout well life cycle.


“Rein has been a constant source of technical and managerial advice, able to bring a deep holistic understanding to any Well Services issues, regardless of the level of the problem. He has a complete knowledge and experience across all aspects of Well Servicing, which he is only too happy to share with the entire team.”
~Iain MacDonald, Senior Well Intervention Engineer (SubSea), Shell

“Rein is a highly experienced well services professional with excellent technical discipline skills. He has good mentoring, coaching and facilitation skills. He was able to propose and implement significant improvements to development well completion design within a tight deadline and despite the poor support infrastructure.”
~Erik Koppe, Drilling Operations Manager, Addax Petroleum

Who Should Attend

Personnel directly responsible and or involved in Well Integrity, its design, verification and intervention should attend.

Job titles include but are not limited to the following:

  • Completion Engineers
  • Well Services Engineers
  • Well Integrity Management Engineers
  • Drilling/completion/intervention engineers (including drilling supervisor and drilling superintendent).
  • Production Technologists and Production Operation personnel (including OIM, Area Production supervisors)
  • HSE personnel

Why You Should Attend

A well integrity incident and breach of well integrity envelope has the potential to escalate into a catastrophic event. The event can result in harm to people, damage to Assets to the environment and to the reputation of the Operator.  Attend this event to learn how to protect your well integrity.

Key Learning Points

  • Understanding of the WIM principal, barriers, conflicts in the organisation that threaten a lesser level of WIM construction or maintaining it
  • Discuss well-completion design and construction to create a “integer” well with lowest life cycle maintenance cost from a WIM prospective
  • Develop preventive maintenance strategies to manage the well integrity issues
  • Investigate and managing well integrity issues and the causes.
  • Understand repairs of loss of well integrity envelope
  • Repair and reinstate loss of well integrity and abandonment

The Process

To assure Well Integrity it is of paramount importance to know where and how the Well Integrity Management (WIM) process shall start.

This Class teaches this process from the onset of the well; The Field Development Plan (FDP), throughout the well design, well construction, Well Integrity intervention to verify sustained Integrity and the reinstatement of the Integrity envelope and finally abandonment.

Consequences of a breach or loss of the integrity envelope can be very high; loss of revenue of the hydrocarbons that escape, damage to the reservoir as a result of the uncontrolled flow and collateral damage has the potential to bring an Operator in financial dire straits.

Several incidents in the recent past have shown that even the largest Operator can barely manage such financial drain.

The well integrity envelope needs properly design, construction and to be maintained during it life cycle: Managing Well Integrity through design, verification and repairs.
