Materials continue to be the primary challenge facing the development of deepwater assets, and have played a major role in the success of these developments. This session will highlight the challenges faced, reflecting on lessons learned and the challenges remaining both in meeting the desired properties, system performance, availability, economics, and asset integrity.
Session Chairs: Cristina Grigorescu, Genesis Oil & Gas; Ashutosh Kak, Genesis Oil & Gas
Production systems are often designed and operated at high single-phase initial flow rates then operated as multiphase flow (gas/water or gas/liquid) systems. In late-life production, solid particles carried in the flow increase the erosion risk. In addition to these solids, when corrosive species co-exist in the production fluids, complex erosion-corrosion mechanisms could develop. The interaction between multiphase flow and solid surfaces, erosion and erosion-corrosion models, and experimental and field evidences of such damage mechanisms will be addressed.
Session Chairs: Nicolas Tsesmetzis, Shell; Victor Keasler, Nalco Champion
Microorganisms can cause significant issues in oilfield systems including corrosion, biotic H2S production, and biofouling. Unfortunately, there is a general misconception in the industry that these microbial risks are not present in HPHT systems. This session will address the microbial risks that are present in HPHT systems, and provide information on how these organisms survive and thrive, and the threats they pose.
Session Chairs: Victor Keasler, Nalco Champion; Sai Venkateswaran, BP
Monitoring corrosion in deepwater systems can be challenging, but is critical for asset integrity. Corrosion can present itself in a variety of forms such as CO2, H2S, and microbial corrosion. This session will focus on describing these unique monitoring challenges, and will discuss best practices.
Session Chairs: Saadedine Tebbal, SET Laboratories, Inc.; Ting Chen, SET Laboratories, Inc.
Some of the environmental conditions prevalent in deepwater are outside the range of current experience and predictive models. Thus, corrosion testing is vital to the front-end engineering design phase when developing deepwater projects. This session will address the current corrosion testing methods and the future needs to predict service life accurately.
Session Chairs: Sunder Ramachandran, Aramco Services Company; Myles Jordan, Nalco Champion
Deepwater and deep/high temperature wells are expensive facilities, and require as few interventions as possible. Different methods of preventing corrosion and scale in high and low velocity systems will be discussed along with case studies showing prevention of corrosion and scale in systems with carbon dioxide and/or hydrogen sulfide.
Session Chairs: Rodrigo Himiob, Wood Group Mustang; Clark Weldon, CP Weldon & Associates, Inc.
The session will focus on challenges associated with the design, installation, monitoring, and maintenance of cathodic protection, coating, and thermal insulation systems in deepwater developments
Session Chairs: Mark McQueen, INTECSEA Engineering; Jason Hults, Genesis Oil & Gas
This session will address critical issues faced by unforeseen localized corrosion and environmental cracking of materials over the asset's life -cycle. The role of corrosion and materials performance within integrity management, the risk-based approaches to localized corrosion, modeling, and mechanical integrity, and the materials selection and performance, corrosion assessment, and mechanical integrity for the life cycle will be discussed.
