Technical Session 1: Microbiologically Influenced Corrosion (MIC)

Session Chairs: Ismenia Alvarez, Apache North Sea; Torben Lund Skovhus, DNV GL

Bacteria and Archaea are micro-organisms that cause severe problems for the oil, gas and petroleum industry. This includes reservoir souring, equipment fouling and plugging caused by slime, biofilms and solids. Microbiologically influenced corrosion (MIC) has also led to failures followed by unplanned shutdowns. Molecular microbiological methods (MMM) are now widely applied in the industry and have proven accuracy as diagnosis tools for monitoring microbes, as well as for identifying troublesome microbes that cause reservoir souring and MIC. This technical session will focus on recent results that show how MMM can be used to model MIC mechanisms. The session will also examine how microbial activity modelling can effectively assist in defining biocide strategies. Such strategies are essential when establishing microbiological controls in an ecologically sensitive environment, while concurrently meeting the demands that parallel asset life extension.

Technical Session 2: Operator Field Experience

Session Chairs: Zeinab Marsh, TAQA Bratani; Catriona Smith, BP Exploration Operating Company Limited

In an industry that has now had several decades of oil exploration and production, many facilities have exceeded their original design life. There is extensive experience in corrosion management and materials selection with respect to successes and failures. Sharing these experiences is essential to allow lessons to be learnt as we go forward into the next era. This will enable optimisation of the integrity of facilities and pipelines on existing assets and on new projects. A number of papers will be presented which will outline some key factors that have influenced corrosion management in operations, over a number of years.

Workshop Session 1: Do We Understand Corrosion in Extreme Environments?

Session Chairs: Mohsen Achour, ConocoPhillips; Jonathan Marsh, Marsh CMI

Corrosion control in commonly encountered CO2 and H2S containing environments is fairly straight forward when operating conditions remain relatively constant and production forecast is well predicted. However, the ‘easy oil’ is diminishing, the remaining oil and gas resources seldom need advanced completion and production practices resulting in more severe environments. Such environments will introduce challenges in corrosion control. The objective of this workshop is to share knowledge around corrosion management in severe environments such as HT/HP, deep water operations, enhanced oil recovery using lift gas, fracking or water  flooding, erosion/corrosion, high chloride environments, and solids containing productions to mention a few. Short technical presentations will be given by invited guests and discussions will follow.

Workshop Session 2: Corrosion Management—Working Together?

Session Chairs: Neil Bretherton, NALCO Champion; Eugene Ogosi, Apache North Sea

To avoid asset failure due to corrosion, it is essential for operators to develop, implement and continuously improve a set of targeted corrosion management activities. A number of short presentations will be given during this session on a range of topics related to corrosion management. These presentations will be short allowing time to debate and discuss topics openly within the forum. Topics will cover various elements of corrosion management process and focus on ideas on how corrosion management professionals can work together and effectively with professionals from other disciplines to achieve ‘good’ corrosion management.
