We all want to achieve an excellent cement job every time, we pride ourselves in achieving this. 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 […]
What can you expect in an Expert Post-Job Analysis?
Please support better well cementing. A 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?

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 […]

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 […]
