For drilling staff, calculations are part of their daily work. The average driller or toolpusher probably has available three choices when it comes to rig maths: 1. Calculator, together with formulae to use. 2. Generic software like Excel. 3. Specialist software, usually commercial. There is now another way. With Internet access and a web browser, standard drilling calculations can be done using web-enabled Mathcad worksheets, which document all of the formulae and intermediate calculations. They are also optimised for small screens, such as the iPhone or other web-enabled PDA.
