In recent weeks, I received some reader requests to include cement job processes or procedures as reference material on the website. I was initially puzzled about the best way to do that without going into too much detail. I went to work to think of whether a cementing flowchart would capture everything sufficiently. How can […]
Webinar series (II). Quality Assurance in Cementing Operations (Spanish)
I am very happy to present here a webinar series on well cementing for my Spanish-speaking readers. This time from a good friend and former colleague, an expert in well cementing from my Mexico days, now a well known professional in the Americas. Mr Diego Florez. This second webinar is about Quality Assurance in Cementing […]
How many cementing centralizers does one really need for a given well?
The primary objectives for centralization design (that is the number, type and spacing of cementing centralizers) should satisfy both the need to get the casing to the bottom as well as zonal isolation. However, despite this being apparently simple and obvious, cementers do not seem to appreciate the fact that without the casing at target […]

Workover Cementing Techniques 2: Squeeze Cementing
Squeeze cementing is basically a filtration process that occurs during the placement of the cement slurry into a wellbore entry point (casing leak, existing perforations, etc.) under sufficient differential pressure. The cement slurry is held in place until it cures and establishes a hydraulic seal. Look at this picture in Squeeze Cementing Principles explaining the […]
