COURSE OVERVIEW:

Cementing Fundamentals and Job Design is a critical course that covers the science and engineering required to place a durable cement sheath between the well casing and the formation. This process is the "one-shot" opportunity to secure the well for its entire productive life. The course provides a deep dive into the chemical composition of oilwell cements, the additives used to modify their properties, and the mechanical engineering required to ensure the slurry reaches its intended destination without contamination.

The scope of this program includes the rigorous design of slurry formulations, where participants learn how to balance thickening time, fluid loss, and compressive strength development. A significant portion of the course is dedicated to the hydraulics of cement placement, focusing on how to achieve effective mud displacement. Attendees will study the importance of centralizers, spacers, and flushes in preventing the formation of mud channels, which are the leading cause of primary cementing failures.

Coverage also extends to the practical aspects of operational planning and execution. Participants will learn how to interpret cementing calculations, select the appropriate mixing equipment, and monitor real-time data during the job. By understanding the interaction between the slurry and the wellbore environment, engineers will be able to design cementing programs that can handle challenging conditions such as weak formations, high-pressure zones, and deviated wellbores, ensuring a successful first-time operation.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Explain the chemical manufacturing process and classification of API cements.
• Identify the primary functions of cement in well construction and completion.
• Select appropriate additives to control thickening time and slurry density.
• Design cement slurries with optimal fluid loss and free-water properties.
• Calculate slurry volumes, additive requirements, and hydrostatic pressures.
• Analyze the rheology of cement slurries and its impact on pumpability.
• Apply mud displacement mechanics to ensure a clean casing-to-formation bond.
• Determine the optimal placement of casing centralizers using specialized models.
• Choose the correct spacers and flushes to prevent fluid contamination.
• Evaluate the risks of gas migration and implement appropriate control measures.
• Describe the operation of cementing units, tanks, and bulk delivery systems.
• Interpret real-time pressure charts during the cementing execution phase.
• Formulate contingency plans for common cementing operational hazards.

TARGET AUDIENCE:

Drilling Engineers, Well Site Supervisors, Cementing Service Technicians, and Petroleum Engineering Graduates.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
