Extended Reach Well Design and Operational Practices

Disciplines: Completions | Drilling

Course Description

The primary objective of this course is to help attendees learn about the physics impacting extended reach wells. Attendees will learn about the challenges associated with successfully constructing extended reach wells and deployment of completion equipment and how to use the laws of physics to deploy drill each hole section, successfully deploy tubulars, and analyze residual stresses in the tubulars (compression and twist) once deployed at TD.

Topics Covered:

  • Hole Cleaning Fundamentals
    • What factors impact hole cleaning in extended reach wells
    • How changing hole size, drill pipe size, flow rate, and fluid properties impact hole cleaning efficiency
    • How will hole cleaning time change as wells get longer
  • Tripping and Backreaming Fundamentals
    • What practices can be used to prevent stuck pipe and NPT while tripping out
    • When is backreaming a good idea
    • How to backream successfully
  • ECD and Surge/Swab Fundamentals
    • What impacts ECD and S&S
    • Why are ECD and S&S design factors for ER wells
    • How to manage ECD and S&S risk from both the design and execution perspective
  • Running Casing and Liners in ER Wells
    • What mechanisms prevent the casing/liners from getting to bottom?
    • Tricks to successfully deploy casings/liners to TD (tubular properties, rotation, floatation, swivels, etc)
    • How do the residual stresses within the tubulars impact how production operations are performed?

Learning Level

Introductory to Intermediate

Course Length

1 Day

Why Attend

As wells become longer at very shallow TVD, there are extreme technical challenges to overcome to ensure wells can be drilled to the required depth and all required completion equipment deployed to the required depth.

K&M Technology Group has been assisting operators design and execute some of the longest and most complex wells around the world, from Sakhlin Island to Qatar to the United Arab Emirates to Alaska to Western Canada.

Who Attends

Drilling Engineers, Completions Engineers, Drilling Superintendents, Drilling and Completions Managers, Development Engineers

Special Requirements

Involvement with SAGD well design and execution for any attendees.


0.8 CEUs are awarded for this 1-day course.
