No prior cementing experience is required.

This course is structured to guide you from fundamental concepts to operational application. However, to get the most out of the technical modules:

• A basic understanding of general drilling rig operations and terminology is beneficial.

• Basic numeracy skills are recommended for the Slurry Design and Calculations modules.

This course is designed for technical staff and operational personnel who require a solid grounding in well construction integrity. It is ideal for:

Drilling & Completions Engineers: Early-career engineers seeking to understand the critical parameters of slurry design and placement mechanics to plan effective cement jobs.

Rig Supervisors: Operational leaders responsible for overseeing the cementing service company, verifying calculations, and making critical decisions during the job.

Cementing Service Personnel: Field operators and trainees looking to bridge the gap between practical rig-work and the underlying theory of fluid chemistry and displacement.

Rig Crew (Toolpushers & Drillers): Senior rig crew members who need to understand how the cementing phase impacts overall rig safety and timeline efficiency.

Technical Support Staff: Procurement, logistics, and HSE personnel who handle cementing contracts, chemical supply chains, or waste management compliance.

This course is delivered 100% online through the OIS Learning Hub. You can access the modules on-demand, allowing for continuous learning that fits your own pace and schedule.

We offer flexible solutions for skill enhancement across your organisation and a discounted rate for groups.

For larger groups, this course can be delivered as a private, tutor-led session (either online or in a classroom). We can also develop bespoke courses tailored to your company's specific operational challenges or assets.

Upon enrolment, you will have 12 months to all course materials, including any updates. This allows you to revisit key concepts as needed.

Upon successful completion of all modules, you will receive an Instant Certificate of Completion. This digital certificate can be downloaded, printed, or shared on your professional profile as proof of your personal advancement.

OIS will set-up your staff with access to the platform, they will be able to get started straight away. For large groups, we will agree a cost and get a formal quote to you.

Curriculum Breakdown

Module 1 – Introduction to Oil & Gas Well Cementing Establish the context for the entire course by defining the role of cementing in the well construction lifecycle.

• What is Oil & Gas Well Cementing? Understanding the process of placing a cement sheath around the casing.

• Why is Cementing Critical: The vital role of zonal isolation, casing support, and corrosion protection.

• Basic Cementing Materials: An overview of Portland cement classes and fundamental chemistry.

Module 2 – Cement Slurry Design & Properties Dive into the science of fluid engineering to ensure the cement slurry meets specific downhole requirements.

• Density: Controlling hydrostatic pressure to prevent formation influx or fracture.

• Rheology: Optimising flow characteristics for efficient mud removal and placement.

• Fluid Loss: Preventing rapid dehydration of the slurry into permeable formations.

• Thickening Time: Designing the "pumpability" window to ensure safe placement.

• Compressive Strength: Ensuring the set cement can withstand mechanical stresses.

Module 3 – Primary Cementing Operations A comprehensive, step-by-step walkthrough of a standard primary cementing job.

• Preparation: Circulation, conditioning, and pre-job safety meetings.

• Mixing the Spacer: Designing spacers and flushes to separate mud from cement.

• Mixing the Cement Slurry: Techniques for consistent density and additive blending.

• Displacement: The mechanics of pumping the plug and displacing the slurry.

• Annulus Placement: Flow regimes required to effectively fill the annular space.

• Bump the Plug: Confirming the volume pumped and checking for leaks.

• Wait on Cement (WOC): Understanding setting times and transition periods.

Module 4 – Special Cementing Operations & Additives Explore advanced techniques and chemical solutions for complex wellbore challenges.

• Types of Cementing Operations: Differentiating between Primary, Squeeze, and Plug cementing.

• Advanced Additives: Using retarders, accelerators, and extenders to manipulate slurry behaviour.

Module 5 – Cementing Problems & Evaluation Learn to identify issues during and after the job to ensure well integrity.

• Common Cementing Problems: Lost circulation, channelling (poor mud removal), and gas migration.

• Cementing Evaluation: Methods for verifying the bond quality, including pressure testing and wireline logging (CBL/VDL).

Module 6 – Cementing Equipment Familiarise yourself with the hardware used to mix, pump, and place the slurry.

• Surface Equipment: Bulk storage silos, recirculating mixers, and high-pressure pumping units.

• Downhole Tools: Float collars, guide shoes, and centralisers to ensure concentricity.

• Operational Safety: High-pressure safety standards and equipment maintenance.
