Drilling and Reservoir EngineeringWell Cementing Design and Operations
Sustained casing pressure on an old well can usually be traced back to the primary cement job: a channel left by poor centralisation, a slurry that gelled before it was placed, a spacer that never cleaned off the mud cake. Delegates study cement chemistry and API classes, additives for density, thickening time, fluid loss and gas migration, and the laboratory tests that prove a design. Placement is then engineered: centraliser spacing, displacement efficiency, spacer and wash design, pressures during pumping and job simulation. Liner, stage, squeeze and plug jobs are covered alongside foamed and lightweight systems. Evaluation with CBL, VDL and ultrasonic logs closes the programme. Delegates leave able to design a slurry and job plan, supervise placement and judge whether zonal isolation was achieved.
Course objectives
- Explain hydration chemistry and the properties of API cement classes
- Select additives to control density, thickening time and fluid loss
- Interpret laboratory test results for a proposed slurry
- Design spacers and washes that remove mud and mud cake
- Calculate centraliser placement and expected standoff
- Plan pumping schedules that respect the fracture gradient
- Design squeeze and plug cement operations
- Interpret cement bond and ultrasonic logs to assess zonal isolation
Who should attend
- Cementing engineers and field specialists
