Introduction

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.

This 4-day intensive GLOMACS Xmas Trees and Well Heads training course will highlight:

  • All components of a Well Head and of a Xmas Tree and installation sequence
  • Investigation, mitigation and cure of SAP Pressures
  • Casing and Tubing Seals (monitoring and leak repairs)
  • Different Causes of SAP Pressures
  • Hazards originated by faulty wellheads (and their mitigation)

Objectives

The main goals of this GLOMACS Xmas Trees and Well Heads training course is to (1) revisit 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, (2) To understand how critical are good Cementations to avoid future well Heads and well Integrity Problems, and (3) To understand SAP Pressures, their origin and their impact on Safety and Well Life Cycle.

By the end of this GLOMACS training course, participants will learn to:

  • 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)
  • Investigate SAP pressures based on well pressure monitoring using 2 and 3 pen recorders
  • Explain influence of corrosion models on MAASP pressures and on Well Life Cycle

Training Methodology

This GLOMACS Xmas Trees and Well Heads training course will be presented using properly designed slides, some with animation and several videos on relevant issues. A printed manual containing all the slides and/or electronic form in PDF will be delivered to each attendant. Teaching methods include also calculations on related issues.

Who should Attend?

This GLOMACS training course is suitable to a wide range of professionals but will greatly benefit: 

  • Field Services Foremen
  • Operations Foremen
  • Petroleum Engineers
  • Production Engineers
  • Drilling Engineers
  • Completion Engineers
  • Oil Field Technical Staff
