WELL PLANNING I
Introduction
Based on 31 years of student evaluations, this Well Planning I short course is rated as the “Best in the Business”. It is an applications drilling course covering the design of a well. As in any engineering design, the objective is to affect a "safe" design for minimum "expense". By attending this drilling course you will learn how to choose the criteria for design, how to logically and efficiently perform the design sequence, and how to present the resulting well plan in a usable form.
The drilling course is presented in lecture form and reinforced first with practical example solutions and finally with a question - response discussion. A final project is performed in class to tie all aspects of the course together.
What You Will Learn
What You Will Take Away
Who Should Attend
Certainly everyone who might be called upon to contribute any portion of a well program or prognosis should attend this course. Also, anyone in the operations, contract, or service industry who might have cause to follow parts of a well plan or prognosis will benefit from attending the course.

What You Will Learn
- The sources of abnormal formation pressures and how to quantify their magnitude.
- The models available for fracture gradient determination.
- The ethics of design.
- The criteria of design for any well.
- The actual selection of the casing points for a mechanically sound well program.
- The basics of casing design.
- The actual design of conductor, surface, intermediate, drilling liners, production liners, and the back casing strings.
- The basis for understanding and using API BULL 5C3, API Spec 5C5 and NACE MRO 175-90.
What You Will Take Away
- A working knowledge of how to quantify the formation pressure/fracture gradient system for a well you plan to drill.
- Full understanding of why casing needs to be set at certain points in a well as well as how to determine those points based on your specific criteria for design.
- Comprehension of the strengths of casing and how a specific area/well casing design is performed.
