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)
Though I am far from being an animation expert, during my training courses I have always wanted to show my students a video with the complete sequence of the coiled tubing cementing process. Recently, I finally found the time and “patience” to make that very video. This will be part of a full post on […]
Plug and Abandonment Webinar (Español)
I am very happy to present here a webinar on plug and abandonment on well cementing for my Spanish-speaking readers. This webinar comes to you from a good friend and former colleague of mine, an expert in well cementing from my Mexico days who is now a well-known professional in the Americas: Mr Diego Florez. […]
Is a base necessary for your Cement Plug? – Part 2
In Part 1, I mentioned why cement plugs had taken a leading role in this website. It is so relevant to do sound engineering to avoid non-productive time and reduce the risk of even more disastrous consequences, like a placement pipe stuck in hard cement. In this subsequent post, I would like to introduce a […]
A Cement Plug… just get it right the first time! – Part 1
In the past, I have written extensively about plug cementing, perhaps more than any other topic on this website, and the reason is simple: cement plugs are challenging. In my case, my eyes started to open back in Mexico while attempting deep sidetrack cement plugs. An SPE resulted from that trauma in Mexico after we […]
Support Better Cementing for All – Empowering Oil Well Cementers
In 2016, I launched Better Cementing for All. Since then, it has been visited by many thousands – and probably by hundreds of oil well cementers. Now, I want to keep it alive. For more than 24 years, I have worked in oil well cementing, offering my services to some of the largest oil corporations […]
