X-mas Trees and Well Heads: Operation and Testing

Course Cost £3038 +VAT
Duration 4 DAYS
  • Well heads and X-mas trees are critical for well operation and integrity. Boost production and prevent well inactivity. Importance of good cementations and understanding SAP pressures. Target audience includes field services, engineers, and technical staff. Course covers well head integrity, safety, and production issues.

Overview

The Well Head Training Course focuses on the importance of well heads and X-mas trees for maintaining well integrity and boosting production. Participants will learn about cementation, SAP pressures, and well construction to prevent issues and ensure safety. The course is designed for field services personnel, engineers, and technical staff in the oil industry. Through discussions, case studies, and practical exercises, attendees will gain confidence in identifying leaks, investigating pressures, and understanding corrosion models. The course spans 4 days and covers topics such as well head components, pressure testing, well integrity, and industry standards.

Course Content

DESCRIPTION

Well heads and X-mas trees are very important and critical components of any well. To monitor, test and repair any failed component is critical for the safe operation of the well and will boost production and keep the well out of the ‘inactive wells’ list.

The main goals of this course are to:

  • Revisit the importance of well heads and X-mas trees and to analyse all the problems that may affect well head and X-mas trees integrity and well integrity as a whole
  • Understand how critical good cementations are to avoid future well heads and well integrity problems
  • Understand SAP pressures, their origin and their impact on safety and well life cycle

DESIGNED FOR YOU, IF YOU ARE…

  • A field services or operations foreman
  • A petroleum or production engineer
  • A drilling or completion engineer
  • Oil field technical staff

HOW WE BUILD YOUR CONFIDENCE

  • Discussing and analysing how well heads and Xmas trees have a major role in achieving well integrity
  • Correlation between best practices for well construction and well heads integrity, and how they can affect safety and well production issues
  • Focus on SAP pressures registered at well heads, their causes and mitigation
  • Videos, exercises and case studies will be presented

THE BENEFITS FROM ATTENDING

By the end of the course you will feel confident to:

  • Develop the knowledge relationship between surface (well heads) and downhole
  • Investigate leaks and identify the cause of leaks
  • 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

Testimonials

We’ve helped thousands of professionals grow their skills and confidence. Hear directly from the people who’ve taken our training courses.

The course was exceptional, well run in terms of delivery of information, IT online course but seamless. Very interesting examples of temporary works failures applicable to the businesses we worked in. Break out activities / group examples worked very well and were again well managed by the trainer. Fantastic course, I will recommend to others! Best course I have attended in years!

Black & Veatch

The trainers knowledge was excellent and I liked his examples and how he could relate them to every day relatable examples that we could all understand. Coming from different industries and sectors his examples were a common ground. It was handled very well virtually and the engagement worked with his questioning and answering
