The central design tension is between pumpability and strength. The slurry must stay fluid for the placement time plus a safety margin, then set quickly. Retarders control the first part and the temperature profile controls both, which is why bottomhole circulating temperature estimation is as important as the chemistry. A slurry retarded for the bottom of the hole may never set properly at the top.

Gas migration is the failure mode that causes most long-term integrity problems. As cement transitions from fluid to solid it loses the ability to transmit hydrostatic pressure before it has the strength to resist gas entry, and gas can channel through during that window, leaving a permanent pathway. Static gel strength development, fluid loss control and specific anti-migration additives address it.

Laboratory testing only predicts field performance if it is done at field conditions. Thickening time run at the wrong temperature ramp, strength tested at the wrong pressure, and mixing procedures that differ from the field all produce results that are reassuring and wrong. This course gives as much attention to test conditions and procedures as to the chemistry itself.

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

• Explain cement chemistry, hydration and strength development.
• Select additive systems and predict their interactions.
• Design slurries for required thickening time and strength development.
• Control fluid loss, free water and settling.
• Design lightweight, foamed and high density slurry systems.
• Design slurries for high temperature and high pressure wells, including silica stabilisation.
• Design for salt, acid gas and corrosive environments.
• Design and verify gas migration control.
• Specify laboratory test programmes and test conditions that match the well.
• Translate laboratory results into field mixing and pumping procedures.

The course is instructor-led and laboratory-focused, pitched at engineers who already understand primary cementing. Participants specify test programmes, interpret laboratory reports and identify where tests do not represent well conditions. Design cases cover high temperature, gas-bearing and weak formation wells. Participants are encouraged to bring their own slurry designs and laboratory reports for discussion.

Organisations sending participants to this training will:

• Improve cement job reliability through better slurry design.
• Reduce gas migration and long-term annulus pressure problems.
• Specify laboratory programmes that predict field performance.
• Improve technical review of contractor slurry designs.
• Extend cementing capability into demanding wells.

Participants will:

• Understand cement chemistry and additive interactions.
• Be able to design slurries for difficult conditions.
• Be able to specify and interpret laboratory testing.
• Understand gas migration and how to control it.
• Be able to review and challenge slurry designs.

• Cementing engineers and specialists
• Drilling and well engineers
• Well integrity engineers
• Cementing service company technical staff
• Laboratory personnel
• Technical authorities reviewing cement designs

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.
