01/12/2020 - OCTGOn November 5, 2020, Vallourec held a live webcast introducing the latest developments in our comprehensive tubular offer in high-strength sour service grades. Presenting for Vallourec was Jonathas Oliveira, Vallourec’s Marketing and Development Coordinator for Oil Country Tubular Goods (OCTG) Grades, a senior expert with experience with material design, rolling and heat-treatment process, and material selection advisor for OCTG pipes in downhole conditions. The webcast attracted more than 230 participants from the oil and gas industry.
What is sour service?Sour service refers to oil and gas exploration and production environments that have enough hydrogen sulfide (H2S) gas to crack metallic materials. Hydrogen sulfide is highly flammable and explosive; it is deadly even at very low concentrations. Sour service is one of the toughest challenges in hydrocarbon production, and due to a recent dip in oil prices, well operators are now looking for even more cost-effective solutions that combine high-strength steels and resistance to sulfide stress cracking.
High stakes, big challenge“Within the numerous difficulties faced by companies in the oil and gas industries, sour service operations remain among the most challenging,” explained Jonathas Oliveira. “When facing a reservoir with significant H2S content, well equipment requires a specific metallurgy to avoid critical failure. OCTG casing strings, which are not expected to have long term contact with production fluids, must be sour service resistant as they are designed as second barrier in case of tubular leak and SSC failure develops very quickly – in some hours.”
An offer to meet every needVallourec’s expertise in material science, pipe production technology, and corrosion combine to create an offer that is perfectly adapted to this high-stakes challenge. Whatever the level of difficulty of the well environment, Vallourec has a tubular offer in high-strength sour service grades to meet the need.
As a tube’s mechanical properties increase, it becomes more and more difficult to achieve enhanced sour service resistance. The latest metallurgical developments have enabled us to create a full range of sour service solutions suitable for all well conditions, and to propose powerful cost-effective solutions to overcome our clients’ challenges.Jonathas Oliveira Vallourec’s Marketing and Development Coordinator for Oil Country Tubular Goods (OCTG) Grades
