Extreme fatigue resistance
The Baker Hughes enhanced Aptara™ standardized fatigue resistant wellhead solution (Aptara SFX) takes the field-proven architecture of our MS-700 and MS-800 subsea wellheads to the next level—delivering up to 20 times the fatigue resistance of existing systems. With its stress-reducing geometries on extended-length forgings, tougher materials (A707 and F22) and reduced number of welds, the Aptara SFX is stronger—providing industry-leading reliability in extreme fatigue conditions. The system delivers this improved performance while maintaining all the familiar system interfaces, tools, and operating procedures that have been proven in fields across the globe. This minimizes risk and improves safety by reducing management of change.
Maximizing our customers’ life-of-field options
The Aptara SFX wellhead solution is focused on improved fatigue resistance to maximize life-of-field options for our customers. Our life-of-field approach to design enables production enhancement through well intervention activities, even in late life, and ensures longevity of field operations—all with a lower risk profile than traditional wellhead systems. The Aptara SFX wellhead solution enables our customers to plan well activities reliably and with greater confidence for years to come.
Reduced lead times
The standardized solution optimizes supply chains, simplifies operations, and—with lower fatigue damage rates than traditional wellheads—enables our customers to extend drilling days in harsh environments. The Aptara SFX is also available in reduced cycle times: by eliminating the incremental six months of material-procurement lead time, we can deliver a make-to-order variant with configured options within six months.
The Aptara SFX can be supplied in both MS-700 and MS-800 configurations and comes with 5 inches of extra sealing surface for compatibility with all completion systems. Available with optimized C1 or automated orbital C class performance welding—with tight pipe tolerance providing industry-leading girth-weld fatigue-life performance—the Aptara SFX wellhead family can be supplied with fabrication options, optimizing fatigue resistance solutions for extreme environments and applications, anywhere in the world.
The comprehensive system includes wellhead, pipe, and casing connectors, all designed to meet or exceed industry standards for materials, quality, and fatigue performance. The Aptara SFX also comes with improved and standardized inspection protocols for greater safety and reliability.
