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 […]
Ever Been Suddenly Covered in Fluid on Location? Share Your Photos!
Working in heavy rain with the boots filled with water, mud-sprayed on the rig floor and, yes, covered in cement slurry from head to toe… All of this has happened to me. The following picture is of me covered in fluid: What about you? In our line of work, these events are pretty common, but […]
Where is your TOC now? Cementing Calculations Sheet in Excel
Before we get into the cementing calculations sheet available below, first some background. For some time already, I have been receiving requests from friends and readers, mostly drilling engineers and well-site people, to provide a quick and fact-based tool to estimate the top of cement (and all cementing fluids) after a job. A tool that […]
Workover Cementing Techniques. (3) Plug Cementing
Continuing with this 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 are intended for well abandonment. Cement Slurry […]
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 […]
Workover Cementing Techniques. (1) The Injectivity test
This injectivity test page is the start of a series of posts covering cementing techniques applicable during workover, including specific job requirements, fluid characteristics, and testing procedures. We will cover each of the following job categories: Remedial cementing, well abandonment, and fluids control/shut-off. I am initiating this series of posts, (you can find links to […]
