Offshore & Deep Water Drilling

Introduction

This 5-Day course provides a comprehensive, hands-on workshop on the fundamentals of offshore drilling. If you're new to offshore drilling, and looking for a comprehensive overview of how it all really works, the brand-new 5 Day MBA in Offshore Drilling is designed with you in mind. This hands-on training course will walk you through offshore drilling operations, technology, and costs, as well as taking you through issues such as health and safety and environmental concerns. What will this course cover? Difference between onshore and offshore drilling, drilling cost analysis, components of the drilling rig, reasons for directional drilling, tools used for directional drilling, how to optimize parameters (such as bit selection, mud design, casing design and so on), HSE and logistics requirements during offshore drilling.

Objectives

Participants will learn how to:

• Get to grips with the fundamentals of offshore drilling and find out how it differs from land drilling
• Learn all you need to know about the drilling rig, basic well design, drilling bits, routine drilling operations, and much more
• Find out how to carry out a drilling cost analysis
• Discover how to estimate drilling costs, calculate the daily rig rate, and account for variable costs
• Consider the reasons for directional drilling, as well as looking at the tools and measurements involved
• Find out how to select and evaluate a drilling bit, as well as optimizing your drilling hydraulics
• Learn all about the role of weather conditions, supply vessels and seaport facilities
• Explore health, safety, and security in the offshore drilling environment

Training Methodology

The course is delivered in a combination of lecture-style and computer-based training. In addition, a significant amount of time is set aside for small working group activity when addressing case study problems. Extensive use is made of case study material to underline the key aspects of the course and to give the delegates exposure to current best practice.
