X-mas Tree & Wellhead Operations, Maintenance and Testing

Wellhead and Xmas tree is the main equipment for oil production, water injection and down hole operation. It is installed on the casing head to seal the annular space between casing and tubing, control wellhead pressure, adjust well flow rate and transport oil to pipeline.

This course is designed to provide an up-to date overview of x-mas tree, wellhead equipment, mechanical barriers, safety valves and wellhead operating control system. Participants will develop a better understanding of wellhead operating procedures and working under safe conditions.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

• Apply and gain an in-depth knowledge on x-mas tree & wellhead operations, maintenance and testing
• Discuss the various wellhead equipment as well as x-mas tree, tubing hanger, production packers & landing nipples
• Practice barriers principles & well safety on hydraulic barriers and mechanical barriers as well as subsurface control valve packer setting and testing
• Demonstrate flanging of the wellhead, wellhead safety valves and control system
• Apply the proper procedures of x-mas tree and wellhead operations to work under safe conditions
