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 […]
Excellent cement job, but with terrible results … how is this possible?
We can face a common challenge while attempting zonal isolation during primary cementing: the resulting lack of “good bond” – as measured with cement logs – across permeable zones. This is typically seen as a sudden decrease in cement presence (increase in CBL amplitude or decrease in Attenuation in sonic logs or a clearer image, […]
What can you expect in an Expert Post-Job Analysis?
Please support better well cementing Post-job analysis is among the first steps to developing a learning organization, but what is a learning organization? Before answering this question, just very quickly, let us answer a more basic one; where does quality start? Moreover, by “quality,” I mean measurably meeting requirements, expectations or achieving objectives. Quality starts […]
How many centralizers does one really need for a given well?
The primary objectives for centralization design (that is the number, type and spacing of centralizers) should satisfy both the need to get the casing to 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 depth primary […]
Support Better Cementing for All – Empowering Oil Well Cementers
In 2016, I launched Better Cementing for All. 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 in the world and committing myself to excellence. I have mastered my role, and in doing so, I […]
