Session 1: Technical Integrity Design and Well Construction/Completion
Session Chairpersons Alan Brodie, Petroleum Technology Company; Ahmed Magdy, Welltec

What guarantees an operator that they are effectively designing a 25, 30 or 40 year well when planning a greenfield? If well integrity is truly a cradle to grave activity, then robust design is imperative. This session will explore the first step (cradle) to ensuring that a well is designed appropriately from a well integrity perspective. The topics to be explored may include:  

  • Basis of Design (BoD) components: Drilling Phase
  • Basis of Design (BoD) components: Completion Phase
  • Basis of Design (BoD) Criteria for Setting Life Expectancy and How it is Monitored
  • Life Cycle Production Assumptions (hydrocarbon, water, H2S, CO2, sand, etc.)
  • Mid-Life Cycle Corrections to Projected Well Life
  • Impact of Workover on Life Extension

Early phase design and risk mitigation is vital in planning wells, as to ensure the well’s longevity. Implementing design choices to boost the well’s safety performance in addition to its financial robustness should be scrutinised in the design phase. Throughout the lifetime of the well, challenges could be met in terms of barrier integrity, annulus pressure monitoring and management, production optimisation and structural integrity.

Session 2: Well Integrity Maintenance Activity
Session Chairpersons Walid M. Abdulhai, ZADCO; Sami Halfawi, Wood Group Intetech

External corrosion of the surface casing is prevalent in the area. This requires remedial work prior to conducting workover or intervention operations to ensure first level of integrity before the workover commences. This topic presents opportunities to investigate design area for prevention, ongoing activity such as robust cathodic protection for mitigation, and novel repair techniques to expedite resolution. Another area of investigation would be the impact of surface casing corrosion in gas lift wells. This can create a situation where the lift gas enters the aquifer. This in turn can lead to an aquifer kick on the next infill well supported by the gas accumulated.This situation can be compounded by the cumulative risk of oil or dehydration water flowing in the aquifer from sub-hydrostatic wells that have a higher liquid level then the aquifer which is often not recognised.

Session 3: Well Integrity Downhole Surveillance and Diagnostics
Session Chairpersons Ibrahim A. Al Ghamdi, Saudi Aramco; Stuart Girling, Girling McIntosh

Wellbore monitoring and periodic diagnostics are critical to early identification of potential well integrity issues. Some of these can be conducted without impacting production whilst others require taking a valuable producer offline for a period of time and the uncertainty that it will continue to perform at the same level. This session will explore technical discussion and case studies for diagnostic tools, analytical methods and leading/lagging indicators that should be monitored over a well’s life. As these diagnostics expose concerns, the course of corrective actions can be explored.

Session 4: Risks & Prioritisation
Session Chairpersons Eric P. Deliac, Oxand; Ogo Ikenwilo, Wood Group Intetech

The challenges that are related to management of well integrity are considerable in ageing fields, extending the life cycle and the cost of abandonment in a more stringent regulated environment that at the same time demands stronger transparency in assurance managing the wells within operating limits over their life cycle. This section may explore key topics such as:

  • Well Integrity Risk Assessment During Planning
  • Well Integrity Risk Assessment During the Life Cycle
  • Well Integrity Risk Management
  • Well Integrity Risk Management When Re-Tasking Wells
  • Well Integrity Risk Management as a Well Moves (handed over between stakeholder departments)

Session 5: P&A Challenges and Opportunities
Session Chairpersons Corey Hoffman, Wild Well Control; Inge Carlsen, PRORES

P&A operations are a key part of the well life cycle (cradle to grave) process, used to deliver either temporary or permanent well integrity. Often such well abandonment operations, can potentially be more complex to execute successfully than other sub-surface operations during well construction and production. Some areas have old legacy platforms that have challenges such as unknown subsurface conditions including equipment, complicated logistics, etc. These present unique opportunities to employ technology to effectively abandon the wells economically. 

Suggested topics for this session include, but are not limited to:

  • Abandonment criteria: assessing well before final abandonment
  • Case studies to examine re-tasking a well at the end of its economic life to extend the value proposition
  • Abandonment case studies
