DE0420 : API 6A: X-mas Tree & Wellhead Operations, Maintenance & Testing

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops.

This course is designed to provide participants with a detailed and up-to-date overview of API 6A: X-mas Tree & Wellhead Operations, Maintenance & Testing. It covers the components of a wellhead system and the fundamentals of API 6A standard; the X-mas tree system and its functionality in production and injection wells; the wellhead components and functions covering casing heads, casing spools, tubing heads and hangers, sealing mechanisms and load shoulders; the pressure ratings and temperature classes including materials and product specification levels (PSL); the installation procedures for wellhead equipment; and the X-mas tree assembly and installation.

Further, the course will also discuss the BPV (back pressure valve), TWCV (tubing wing check valve) and VR plug installation; the visual and dimensional checks and hydrostatic pressure testing; the leak testing and functional tests and documentation and test records; the maintenance schedules for wellhead and tree components and greasing and seal replacement; the valve maintenance and seat repair and troubleshooting common issues; and the tools and equipment for wellhead maintenance and types of valves in X-mas tree.

During this interactive course, participants will learn the valve operation, maintenance and surface safety systems and SCSSV, emergency shutdown (ESD) and safety protocols; the control panel operations, data logging and performance monitoring; the well integrity testing principles, hydrostatic and gas leak testing, BPV/TWCV and VR plug testing; the non-destructive testing (NDT) methods, flange and stud inspection and test documentation and QA/QC records; the common operational challenges and troubleshooting procedures; the hazard identification for wellhead activities, safe work practices (SWP), job safety analysis (JSA) and barrier management; the isolation of zones and plugging and valve sealing and pressure verification; and the use of plugs and barriers and re-entry planning and safety.
