First, here is a handy table to simplify the process of cement slurry design: Additive Type Purpose Considerations Extenders IWater, Bentonite (clays), pozzolans, amorphous silica, Sodium Silicate, etc. Reduction of hydrostatic or greater economy.Lower slurry density from less than 15.8 down to 11.5 ppg, typically.Higher slurry yield (more slurry volume per sack). Change slurry rheology […]
Remedial Cementing with Coiled Tubing (animation)
Far from being an animation expert, in my training courses, I always wanted to show my students a video with the complete sequence of the CT cementing process. Now I finally had the time and “patience” to make one. This will be part of a full post on remedial cementing with Coiled Tubing, but now […]

Workover Cementing Techniques. (3) Plug Cementing
Continuing with these series of posts covering some of the cementing techniques applicable in workover operations, I want to talk further about plug cementing. In previous posts, I have covered extensively plug cementing. This time I am providing information regarding laboratory testing and some considerations when cement plugs intended for well abandonment. Cement Slurry Properties […]
