Material Selection Services
Viking’s Materials and Corrosion Team is involved with detailed material selection and qualification support with the goal of ensuring the selection of fit for service materials and their appropriate manufacture and fabrication.
This work also ensures that designs conform to the latest codes and standards for downhole, subsea, and topsides equipment, while taking into account past project experience and industry best practice.
Downhole & Subsea Materials Selection
Qualification Erosion/Corrosion Risk Assessment and Modeling Scaling Studies (Formation Risk, Removal and Mitigation Strategies)
Failure Analysis
Protective Coatings and Cathodic Protection
System Design Monitoring And Inspection Strategies During Field Design
Topsides Materials Selection including Protective Coatings, Cathodic Protection Systems, Corrosion Monitoring, and Erosion Monitoring Systems
Linking Material Selection, Selection of Coatings and Field Joints Studies
Inspection and Auditing During Fabrication And Vendor Qualification including Welding, Coating, Anode Chemistry, Positive Material Identification
Downhole Material Selection
Downhole materials selection is one on the most debated topics during the well design process. A material selection that is too conservative can add substantial initial cost of the equipment. A material selection that is not conservative enough may cost substantially more in the long run due to equipment repair, downtime, and environmental and safety problems. Material selection is a problem that can safely be solved and implemented into a well design if there is thorough knowledge of the well environment, the available materials, the equipment, project requirements and load cases.
Viking Engineering has performed many materials selection projects to help operating companies produce oil and gas safely and within budget.
Viking Engineering professional registered engineers, metallurgists, and chemists can:
Perform wellhead, OCTG, and down hole completion equipment materials selection analysis and develop materials specifications that meet the materials selection criteria based on industry standards or based on project specific fit for purpose requirements.
Perform third-party HPHT and deep water offshore materials engineering equipment design reviews for well completion permit approvals by the US government regulatory body (BSEE).
Perform multi-disciplinary materials selection analysis based on reservoir fluid chemistry, completion fluid chemistry, acidizing treatments, metallurgy, and anticipated well loads.
Assist in determining an accurate estimation of the expected well environmental parameters that are crucial in downhole materials selection.
Evaluate water analyses for the purpose of estimating alkalinity, pH, scaling tendencies, perform H2S partitioning studies and model the appropriate corrosion rates. Viking also has access to chemical thermodynamic software packages used in performing these types of analysis (i.e. OLI Stream Analyzer, VGMSim, OLGA, etc.).
Coordinate, develop and design, standard and fit for purpose corrosion and environmental assisted cracking testing protocols, including complex HPHT materials testing and evaluation requirements.
