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.

Well, I did some additional work on an old Excel sheet I developed a few years ago. I completed the first version ready for distribution, here in my blog, of a TOC calculator. This calculator has the following features.

b) Caliper,
c) Casing details,
d) Top of formations (up to 7 formations)

For the complete version of my cementing calculations sheet, I appreciate your kind donation very much (see donation link, via PayPal, at the bottom of this page).
Free version (Donate to get the full version as an Excel file – Donation link in the right pane to the bottom)

Fill only the green cells, paste your Caliper (4-arm) or input manually your hole details and you are good to go!
Scroll to the right to see the chart and if you need to start over just reload the page. The page will return to the example case.
This excel sheet has been tested and it is working great for me, but I am sharing it with the objective to help people. I would like you to try it and give me your opinion or what improvements or changes it needs.
Take a look at the full version with all capabilities.
