Cementing Operations

The course will present an overview of oil and gas well cementing operations. The course includes overview of pore and fracture pressures, overview and discussion on cement properties, measurement techniques and evaluation of results, cement placement techniques, and cement quality evaluation. The course will cover cement standards, cement materials.

At the end of the course delegates will learn about the reasons and importance of cementing operations, about cement properties, how to achieve required properties using appropriate additives, how measurements are performed in the laboratory and in the field, how to design a cement job, how to achieve, how to properly execute the job and how cement job evaluation is performed.

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
