About DrillPro

Last updated 9 November 2026

DrillPro is drilling engineering software for the people who run the well day to day: drillers, assistant drillers, toolpushers, mud engineers, drilling supervisors and engineering students. It puts the sums the rig floor does every shift (kill sheets, trip sheets, hole and annular volumes, mud pump output, mud tank volumes, tubular data and unit conversions) into calculators that work the same way on the web, on Windows and Mac, and on Android.

Why we built it

On many rigs these numbers still live in personal spreadsheets, photocopied forms and notebooks. Each copy has its own constants, its own rounding and its own mistakes, and a wrong strokes-to-bit figure or a mis-entered pit volume is found at the worst possible time. DrillPro started as a way to have one set of carefully checked formulas that a crew can carry on a phone, use offline on the floor and export as a clean PDF or Excel sheet for the morning report.

What you will find on this site

How the content is checked

Every guide uses the standard oilfield constants (0.052 for pressure, 5.615 cubic feet per barrel, 1029.4 for capacity in bbl/ft and so on), and every worked example is recalculated before it is published. The same formulas are covered by automated tests in the app. When we find an error we correct the page and update its "last reviewed" date. If you spot something that looks wrong, please tell us through the contact page.

The guides and the app are calculation and training aids. They do not replace your company's procedures, your well control certification or the judgement of the people responsible for the well. Always verify results with your own rig and well data.
