04-Juin-2015 | Oxand interviendra à la Conférence Decomworld à Aberdeen (UK)

Oxand interviendra à la prochaine Conférence “Well Integrity and Abandonment” organisée par Decomworld à à Aberdeen du 30 juin au 1er juillet prochain.
Cet événement est le plus important d’Europe dédié aux puits offshore ; il rassemble à la fois les opérateurs et les prestataires du secteur pour échanger sur les stratégies d’intégrité et de P&A,
(Plug & Abandon) mais aussi proposer des produits innovants au marché de la Mer du Nord.
Oxand, apportera son expertise et ses solutions portées par sa plateforme applicative Simeo™  pour réduire les coûts et améliorer l’intégrité des puits, notamment en phase de P&A. Oxand présentera particulièrement sa procédure WIRAP (Well Integrity Risk Assessment Process ) dédiée aux puits.

Wells are now facing ‘ageing’ issues. There seems to be a growing need for more robust well integrity processes to ensure safe and reliable containment of fluids throughout the life of a well, including after P&A.
What does your company do and where do you fit in the overall well integrity process?
A.M: Oxand is an independent company which provides risk-based management solutions with an aim to reduce operating costs and improve asset integrity to allow stakeholders to unlock the full potential of their assets. All of our solutions are supported by our software platform, SIMEO™. Within the Oil and Gas industry, Oxand has provided solutions throughout the life cycle stages of assets.
In regards to well integrity, we assess the risks posed to wells and provide our clients with easy to communicate decision support tools. For this we developed a process which we call the Well Integrity Risk Assessment Process or WIRAP. With the WIRAP we are able to tailor our approach to the wells which we are assessing and analyse them at a well system level and component level. We identify and assess the most relevant risks posed to the wells and determine how the whole system will cope with this risk. Using our WIRAP clients have been able to demonstrate the safety of their wells, optimise and prioritise inspection/intervention strategy and make risk informed operational decisions.
We have also developed solutions based around cement analysis. In these cases we analyse potential leakages which could occur through cement annuli and/or cement plugs. Using our models we determine the risk related to leaks through cemented sections of a well and verify whether they are within safety requirements. Clients have been able to avoid unnecessary workovers based on results produced with our robust and technically sound methodology.
What do you see as the main challenges for the North Sea industry?
A.M: With the maturing assets within the North Sea, ensuring integrity of the wells is very important. To be able to do that an understanding of the risks associated with well integrity is required along with an appropriate inspections and intervention strategy. However, compared to other industries risk management in Oil and Gas is not at the same maturity level. Plus, carrying out inspections and interventions can prove quite costly especially in the current market. Therefore implementing a risk based inspection/intervention strategy which ensures safety and is cost effective is a key challenge.
What do you see as the solutions?
A.M: Improving our risk awareness and being more risk informed when it comes to ensuring integrity and making decisions.
In this case, understanding the current conditions of the wells including the downhole conditions is the first step. Based on this understanding, carrying out a risk assessment to identify what are the key threats posed to the wells and recognize consequences associated to these threats. Using the results of a risk assessment and coming up with a risk informed strategy which will help ensure safety and be more cost effective.
What initiatives have you taken to address these challenges?
A.M: We have taken our knowledge from other industries such as Nuclear, Hydro and Rail and combined it with our experience in the Oil and Gas to come up with the WIRAP. Within the process we follow a risk-based approach and use different techniques such as Functional Analysis and Fault Tree Analysis to thoroughly assess the risks to wells. We analyse the probability and consequences of the risks in terms of safety and environmental impact and cost. With our results we are able identify critical components, failure scenarios and wells thus supporting our clients to develop prioritised and optimised inspection/intervention plans to ensure safety and be more cost effective.
Are there any case studies/projects which have shown innovation in the field?
A.M: Companies are starting to invest in projects which help them understand the current condition of their wells. They are looking to understand the risks being posed to their assets. This initiative is helping them become more risk aware and see the benefits of taking risk informed decisions.
Where do you see the industry heading? What will be the norm in 5 years?
A.M: I see the industry being more risk aware and making more risk informed decisions, especially when it comes to ensuring the integrity of their assets. I also see the industry taking more optimisation and prioritisation into account when making decisions, thus allowing it to be more cost effective.
In 5 years, I expect the industry to be more risk informed and more cost effective when taking decisions regarding the ageing well stock and developing plug and abandonment strategies.
