Casing & Well Design

Objectives:

The first design task in preparing the well plan is selecting the depth to which the casing will be run and commented in this course drilling engineer will learn how he can consider geological Conditions as formation pressures and fracture gradients for casing setting depth selection. Also, in this course will discuss the procedures, formulas, and rule of thumb for developing a detailed casing program.
