Course Description
This five days introductory course will cover the history of directional drilling, and provide exposure to the basics associated with directional and horizontal drilling. The course will discuss both the benefits and disadvantages of directional work, along with numerous applications.
well configurations, and well trajectory will be presented, in addition to the types of tools utilized, including bits, down-hole mud motors. The basics of directional data, tool-face orientation,
overview of well planning, and some basic calculations will also be included.
