My new Cement Placement Calculator
Better well cementing for all is not only the name of this website; it is my mission anywhere I go, in any country, or in any operation I provide support for, but my work is not only dedicated to the well and achieving the well objectives, which is fundamental. More importantly, the work with people […]
Balanced-plug method. Basic calculations
Free Balanced Cement Plug Calculator at the end of this post. Check it out ! The most common placement method is the balanced plug technique. The work-string is run into the wellbore to the desired depth for the plug base. Contamination or mixing with the control fluid is avoided by the use of appropriate volumes […]
Max Out Your Cement Coverage
If we consider the main variables to ensure proper mud in hole replacement with cement: stand-off, fluids rheology (friction pressure hierarchy) and placement regime (as related to pumping rate); the amount of cement left in the hole (cement coverage), if no losses, quickly reduces (leading to increase cement returns, either to surface or above the […]
Cementing Flowchart
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 […]
Cementing. Challenges across permeable zones
This article will provide you with some actionable suggestions for cementing across permeable zones. In previous posts, I have already talked about the effect of formation permeability on the apparent cement presence behind casing, as seen on cement logs. (See: Excellent cement job, but with terrible results … how is this possible?) Keep in mind that […]
