Technical Session 3: Chemical Inhibitor Treatments

Session Chairs: Graeme Dicken, Intertek; Andrew MacDonald, Clariant Oil Services

Chemical corrosion inhibitors continue to be a primary barrier for internal corrosion control in oil and gas systems. The varied composition of fluids between reservoirs, both globally and regionally, has a major impact on inhibitor development and performance both in the laboratory and the field. This session will look at a number of influencing factors and the impact they can have on corrosion inhibitor performance.

Technical Session 4: Downhole Corrosion

Session Chairs: Eugenia Marinou, Senergy; Jonathan Marsh, Marsh CMI

Well integrity starts with:

  • A competent well design (including material selection) based on the correct subsurface data
  • A well construction process which reliably implements the approved well design
  • Management systems that adequately control the change of use of a well or its operating parameters
  • Clearly understood operating parameters for the well with control systems
  • Procedures to respond to changes promptly and a system for testing, reporting, recording and repairing wells and maintaining acceptable levels of risk

Downhole corrosion should primarily be prevented at the design stage by building systems and wells which are sufficiently robust in the operating environment throughout the well life cycle. Typically this is mitigated by means of metallurgy, control of the well environment, separation of the metal of the pipe from the well environment and chemical injection, especially since corrosion monitoring is not as straightforward as it is for subsea and topsides facilities. Effective integrity management reduces the risk to people and equipment, reduces environmental risk, improves production uptime, minimises costs and hence safeguards the value of the investment. The subject is of particular significance as the industry is called to face new challenges relating to high CO2, H2S, HP/HT environments and more often than not, downhole corrosion is not apparent until the damage is done.

This session focuses on developments on appropriate material selection and inspection methods and how these can be applied to the holistic management of well integrity.

Workshop Session 3: Failure—Expected or Unexpected?

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

Should we always expect pipework and equipment to fail due to material degradation at some point? Now that the oil exploration and production industry has been around for several decades and many facilities have exceeded their original design life, should we expect to have more failures? For new projects we should not expect failures to occur for years, but still occasional rapid failures do occur. Corrosion management faces challenges on a number of fronts ranging from keeping ageing assets operating safely to ensuring new projects can meet new design lives. This workshop intends to explore these challenges by encouraging discussion and sharing of operator experiences.



Workshop Session 4: MIC—New Standards and Philosophies

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

Operational problems associated with microbiologically influenced corrosion (MIC) are well known to the oil and gas industry, however, accurate and quantitative diagnostic tools have been lacking in the past. Forensic and medical science professionals have used genetic methods to provide valuable diagnostic clues for decades and the application of molecular microbiological methods (MMM) to MIC problems has now begun to see broader practical application in the oil and gas industry. This is mainly due to technology development and its implementation in newly published industry standards.

These recent advances in weaving genetic test methods together with corrosion and material science are characterised by a strong collaborative approach between oilfield microbiologists, corrosion practitioners, pipeline operators, chemical engineers and asset integrity managers. Advancement in the combined application of such diverse scientific and technical fields of MIC management is also promoting a healthy degree of cross-disciplinary learning for all involved. This workshop session will discuss the latest industry standards, technologies and developments in MIC management and mitigation.
