High strength alloys and connection options for extreme HPHT wells

Ultra-HPHT wells are challenging the limits of tubular performance, in terms of metallurgy and threaded connections. But higher pressures and temperatures are only part of the challenge. Carbon steel, hot-rolled chromium-based stainless steel, and coldhardened materials are all options that must be...

Description
Summary:Ultra-HPHT wells are challenging the limits of tubular performance, in terms of metallurgy and threaded connections. But higher pressures and temperatures are only part of the challenge. Carbon steel, hot-rolled chromium-based stainless steel, and coldhardened materials are all options that must be considered to optimize economics in ultra-HPHT applications.
