Course Introduction

•  The  Xmas Trees and Well Heads are critical parts of any Oil & Gas Well.
• They control the pressures in the Casings and Production Tubing, regulate the production rates and are very important barriers in case of leaks
• The 5 days X-mas Tree & Wellhead Operation course will cover the different types of X-Mas trees and  their component  and the function of every parts and wellhead tests

Course Objectives

At the end of this course  the trainees will be able to

• Understand the importance of Well Heads and Xmas Trees and analyze all the problems that   may affect well head and Xmas Trees integrity and well integrity as a whole;
• Understand SAP Pressures, their origin and their impact on Safety and Well Life Cycle.
• Develop the knowledge relationship between surface (Well Heads) and downhole.
• Investigate leaks and identify cause of leak
• Determine Tubing pressures (based on depth of perfs, density of fluid and BHFP).
