A Practical Engineering Reference Library
Calculators, technical notes, and topic overviews for engineers — built from real project and field experience in oil & gas, petrochemical, and process industries
The Engineer’s Notebook is a curated reference of tools, technical notes, and topic overviews drawn from hands-on experience in projects, operations, and day-to-day engineering tasks. Content is organized by discipline and standards so you can find what you need quickly.
This site features articles, tools, and resources inspired by years of involvement in projects, operations, and day-to-day engineering tasks. While many topics lean toward the oil & gas, petrochemical, and process industries, the ideas and resources can often apply across different fields of engineering.
