Directional and Horizontal Wells Course

Introduction:

This course builds a firm foundation in the principles and practices of directional drilling, calculations, and planning for directional and horizontal wells. Specific problems associated with directional/horizontal drilling such as torque, drag, hole cleaning, logging and drill string component design are included.

Participants will receive instruction on planning and evaluating horizontal wells based on the objectives of the horizontal well. The basic applications and techniques for multi-lateral wells are covered in the course.

Course Objectives:

Make survey calculations
Interpret TVD, polar and rectangular coordinates and vertical section
Interpret dogleg severity and the problems associated with dogleg severity
Plan a two-dimensional directional well
Plan horizontal wells based on the objectives of the well
Determine the best multi-lateral completion for an application
Determine declination and non-magnetic drilling collar selection
Apply the best survey instrument for the job
Directionally drill with rotary
BHA’s, jetting, whip stocks, motor, steerable motors, and rotary steerable systems
Drill horizontally underbalanced
Interpret torque and drag and determine what factors will affect the torque and drag.
Determine cementing requirements for directional wells
