About the course

This five-day course builds a firm foundation in the principles and practices of designing, planning and conducting successful casing and cement jobs. The course uses a process-based perspective that takes participants from initial casing depth and size selection, casing and liner design procedures, casing running practices, and planning and executing primary cementing through remedial cementing and plugging operations.

During this course, participants will practice cementing calculations, as well as job design exercises and cement evaluation methods using real-life examples. Liner cementing and stage cementing jobs will be developed in the classroom. Cement design software will also be demonstrated.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Selection of casing sizes and setting depths to achieve well objectives
  • Determination of casing loads for design purposes
  • To design casing properties to meet burst, collapse, and tensile strength requirements
  • To conduct casing running operations safely and successfully
  • Specification of cement slurry properties and volumes to meet well objectives
  • Determination of best procedures for attaining successful primary cementing
  • To conduct stage jobs, squeeze jobs, and set cement plugs, liner cementing and stage cementing jobs
