Master Class – 2/3 days

Drill String Behaviour and Completion Running Analysis

August 29th/August 31st

In collaboration with Ridge
 

COURSE OVERVIEW

This master class introduces attendees to best practices associated with directional drilling, drill string mechanics and completion run-in-hole analysis. The aim of the course is to provide

  • Information on the design and application of bottom hole assemblies that use rotary steerable and steerable motor systems to achieve the directional objectives set for the well
  • Understanding of how drill string design can impact the loads applied at the drill bit, as well as how operational efficiency can be increased by reducing the risk of drill string fatigue life and casing wear
  • Analysis techniques to optimize completion and running string design to ensure successful deployment of lower completions

A combination of instruction, exercises, discussion of real case histories, and hands-on access to advanced simulation software is used to engage participants and ensure improved understanding. Participants can choose to attend for 2 or 3 days according to needs.

TARGET AUDIENCE

This course is designed for drilling and completion engineers with 3 – 10 years’ practical experience of well design and drilling/completion operations.
The course will be held in English and the participants will be required to bring a lap top computer.

COST

Option Cost Who Will Benefit?
Day 1 & 2 12.000 NOK Drilling Engineers with some involvement in completions
Day 2 & 3 12.000 NOK Completion Engineers with no involvement in directional drilling
All 3 Days 16.500 NOK Well Engineers wanting to learn everything and use the software

COURSE OBJECTIVES

The objective of the class is to reinforce knowledge of drill string behaviour and run-in-hole analysis by using advanced technologies and real case studies. Those attending all 3 days will be able to:

  • Describe the main components used in directional drilling bottom-hole assemblies (BHA)
  • Understand how to model BHA behavior and rock interaction to predict directional performance
  • Determine the impact of drilling parameters on drilling performance, to understand risks and anticipate potential problems
  • Perform local dog leg analysis to enable trajectory re-construction and tortuosity assessment to assure successful casing/ liner/completion deployment
  • Explain the theoretical background to torque and drag modelling
  • Understand causes and consequences for performance of sinusoidal and helical buckling in the drill string
  • Predict the degree of casing wear generated by drilling operations
  • Identify how casing centralization can be improved to ensure proper cementation without compromising the ability to reach total depth
  • Anticipate potential lock-up situations and optimize landing string design
  • Understand the mechanical limits while running in hole in complex wells
  • Perform advanced simulations using the WellScan software
