Cementing Operations

Course Description

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.

Course Objectives

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.

 

Who Should Attend

Geo-scientists, Engineers and Managers (in Drilling, Well Intervention/Services, Reservoir Engineering, Production Operations, Marketing/Sales etc.), whose jobs require them to interface with Completion Engineers, Production Technologists, Well Production Operations Engineers, and Well Maintenance/Servicing Engineers who wish to enhance their current job effectiveness, through more knowledge on Well Completion and Performance, than that attained from their own "core" discipline training and exposure.
