Cementing is mostly a displacement problem. The cement has to push the mud out of the annulus, and mud that is left behind becomes a channel. Standoff, flow rate, fluid rheology hierarchy, pipe movement and hole condition all determine how completely that displacement happens, and all of them are decided before the job starts.

Centralisation is the single most effective lever and the most frequently compromised. In a deviated hole with poor standoff, cement takes the wide side of the annulus and leaves mud on the narrow side regardless of how good the slurry is. Standoff calculation and centraliser placement are engineering tasks, not a matter of putting a few centralisers on the shoe track.

Most cement job failures are predictable from the design and the execution record. Insufficient conditioning, no pipe movement, too little spacer, rates too low to achieve the intended flow regime and losses during the job account for most channelling and poor bond. This course covers the design decisions and the execution discipline that prevent them.

By the end of this training, participants will be able to:

• Define the functions and performance requirements of a primary cement job.
• Select cement slurries and additives for the well conditions.
• Specify hole conditioning requirements before cementing.
• Calculate standoff and design centraliser placement.
• Explain displacement mechanics and the factors controlling mud removal.
• Design spacers and chemical washes.
• Calculate cement volumes, excess and pumping rates.
• Design the pumping sequence and placement for the job.
• Specify float equipment, plugs, stage tools and job equipment.
• Apply wellsite quality control, monitor execution and evaluate the job afterwards.

The course is instructor-led. Participants design a complete primary cement job for a given well, including slurry selection, centraliser placement, volumes and pumping schedule, then review execution records and evaluation logs from real jobs. Cement failures are analysed back to their design or execution cause. Participants are encouraged to bring their own cement jobs for discussion.

Organisations sending participants to this training will:

• Improve zonal isolation and reduce cement job failures.
• Reduce remedial cementing and the rig time it consumes.
• Reduce sustained casing pressure and integrity anomalies.
• Improve technical oversight of cementing contractors.
• Support abandonment and integrity requirements with better primary cement.

Participants will:

• Understand what makes a cement job succeed or fail.
• Be able to design a primary cement job from first principles.
• Be able to calculate standoff, volumes and rates.
• Be able to supervise execution and quality control at the rig.
• Be able to evaluate a job and diagnose problems.

• Drilling and well engineers
• Completion engineers
• Rig site supervisors and company representatives
• Cementing service company engineers
• Well integrity engineers
• Graduate engineers in well engineering

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
