Introduction to Deepwater Rig Operations

This course will describe the different types of deepwater drilling units, all their necessary specific equipment and techniques to spud a well. The goal being to transmit to all participants a good knowledge on:

  • Floating drilling rigs (SS / DPDS) and their specific equipment for drilling wells in deep water depth zones (300 - 3000 mtr)
  • Techniques and methods deployed from the arrival of a floating drilling units on a location till the cementation of the conductor casing
  • Major issues and solutions faced in deepwater drilling operations
  • The environmental forces and their impacts on deepwater operations
