In the current challenging cost optimisation environment, a lot of expenses are being saved on well integrity requirements. Integrity is a part of safety. How to find the right balance between safety and efficiency? How to evaluate the well integrity related risks and which level of risk is acceptable? What is the main objective of well integrity business in terms of HSE? What is the right way for handling management of change scenarios? What are the risk acceptance criteria for exemptions and dispensations from well integrity policies? What is the role of HSE in the field operations?
The session will bring more clarity to these hot questions through the actual cases and open-minded discussions among the audience. Can the SAP well be operated? If “yes”—what are the criteria and what kind of control is required?
It is a good chance to share your views on this matter, to receive feedback from the right audience, to benchmark your criteria against others practice and to search for the latest “well integrity life hacks” to be implemented in your company.
Digitalisation in well integrity cannot only bring big data and artificial intelligence (AI) to the industry but will also allow a completely new learning wave, let alone help shape the next decades, with simpler and more efficient operations.
Before making that strategic (and necessary) transformation, we need to be able to find the right tools to leverage the current experience, data, and knowledge. As such, the session will be addressing some basic, yet critical topics:
- What would be the various approaches of getting more value from digitalisation?
- Do we need to re-initiate all well completions, current software, and others—or can we manage to integrate it into our current SOP’s?
- Will AI or machine learning replace well integrity experts or complement them?
Given the infancy of this topic, the session chairs will encourage a roundtable discussion, allowing more interaction between the audience and presenters.
Today, more than ever, the old adage “you only have one chance to drill and complete a well correctly” has never been more true. A properly-constructed well is one that provides the safe and efficient delivery of hydrocarbons and does not require costly work-over programmes. To achieve this goal, engineers use and integrate various simulations and testing tools to help them create drilling programmes that optimise the cost of the operations. Furthermore, they use structured QA/QC processes to identify material/process weaknesses as soon as possible, correct them, and prevent them from causing costly non-productive time events.
This session aims to look at well design with an open perspective, addressing such topics as:
- How can we optimise the well architecture to encompass all requirements that will show up during the life of the well?
- How can we design tubulars and goods that will not suffer from corrosion?
- What is the best approach to design cementing operations?
- How can we optimise communication between various stakeholders to trust design operations, as they are usually performed?
- How can we judge the quality of a design?
- Do we really need to perform testing and simulations or can we rely on other approaches based on artificial intelligence, for example?
All topics will be given a quick introduction, highlighting some issues, and will be followed by discussions.

Well barrier compliance is a critical theme with increasing importance within the oil and gas industry due to the possible impact on safety, environmental protection, and operational performance. Well integrity is characterised by an operating well that has full functionality and two qualified well barriers. However, there are risks to the integrity of well barriers both in newly drilled wells, and in wells that have been in operation for some time. Events have shown that companies have, from time to time, failed to comply with their well barrier policies and standards or with industry best practices.
Well reliability is achieved through the combination of individual barriers as a system and not the result of the infallibility of a single component. The process of well barrier compliance needs to start from the basis of design right through to abandonment. It is the duty of the well operator to define and document a barrier philosophy that specifies the principles of maintaining control of well fluids. A system of multiple barriers and redundancy in well barrier elements is critical in order to achieve a high level of reliability.
Today, a significant number of wells suffer from degraded barriers. Some wells are allowed to continue producing, typically when only one barrier is degraded and the leak is found to be restricted and within acceptable limits. By implementing compensating measures, such as regular monitoring, the overall risk is maintained within acceptable limits. Several oil companies are today classifying their wells according to risk, typically using a colour coding system.
The well barrier compliance process will identify areas where a gap may exist to adherence to applicable policies, procedures and regulations. Some of these areas may include company barrier policies, zonal isolation and breaking containment policies.
This session will discuss current issues experienced by operators with respect to well barriers and compliance, the development of best practices going forward, successes, and case studies.
The evaluation of well integrity in mature wells is critical to the operability of assets in their late life cycle. Early detection of problems as well as their quantitative assessment is of prime importance to enable the remedial and rehabilitation works to be planned in a cost-effective manner. Deteriorations such as corrosion, cement shortfall, and structural damage need to be monitored and evaluated within the well in-place conditions to categorise damage criticality and model their time to failure to prevent an unwanted release. Big data, artificial neural network, and other advanced quantitative methods need to be utilised for well integrity evaluations to aid operators in making decisions and maximising profitability for ageing existing wells.
The session is dedicated to the issues of well barrier management in the most difficult and complicated scenarios of well operation and well intervention. What kind of barrier restoration technologies from service providers are available on the market that have been tested in real-field conditions and are recommended by operating companies? Use this opportunity to share your experience and lessons learnt from well control issues and listen to others. What is the good business practice of dealing with “emergency cases”? What could be the reasons of well control incidents and what kind of prevention and mitigation measures have to be considered? What does the “full investigation” of well control incident mean? What are the pro’s and cons’s of well intervention in a SAP well? What is a “near well control scenario”?
These are the main subjects to be discussed in this session. Let’s make it clear all together!
