Course Description

Casing design is an integral part of a drilling engineer's work scope. This course provides a comprehensive overview of the design process, emphasizing the working stress approach currently used in the industry. Upon completion, participants will be able to select casing points, identify tubular requirements, loads, and present a design which incorporates life cycle considerations. Estimation of standard and special loads is covered in detail. Standard theories of strength and failure are discussed as well as advanced considerations for combined loads. Topics related to safe handling, running and hanging practices will additionally be covered.

Course Objectives

  • Selecting casing setting depths based on pore and fracture pressure data as well as other criteria
  • Determining casing and bit sizes, and alternatives for contingencies and special clearance situations
  • Identifying and define load cases to meet specific design requirements
  • Applying standardized design factors to meet specific design requirements and identify the controlling design load for each string in the well
  • Using and understand casing and connection specifications and select casing to satisfy the controlling design requirements
  • Understanding the limits of single load specifications and adjust the basic design for combined loading effects
  • Designing casing for high pressure fracturing in horizontal wells
  • Applying practical safe handling, running, and hanging

Who Should Attend?

  • Drilling Engineers
  • Service personnel
  • Managers interested in learning about the well design process.
