Strokes Calculator

About Strokes Calculator Android App

Application info.

This and other applications by Oilfield Apps have been created to provide help during rough days/nights on rig or simply to be used as specific calculators. The goal of creating them was to accelerate calculations on fly when they are needed and not to worry about finding or remembering specific equations in order to calculate much needed data.

I have been using many excel files written by myself or my fellow friends from rigs to help myself or others. They were a great success and they have never failed me on the rig or in the office – one day I have decided that it would be cool to have set of apps in my phone I could use anytime – rig floor, pits, etc.

Those apps and calculating functions were crosschecked with many equations from scientific books, papers or excel files. All used in different countries that I have come across during my career – they worked for me and hopefully they should work for you.

However I can NOT guarantee that it will suit you and your needs, since different operators use different factors to calculate or they use different decimal rounding that I have been using while writing those applications and calculating units. Checking my algorithms results, I was able to score less then 0.5% difference between results in worst cases.

That being said, please remember that you are using those applications at your own risk and I can NOT be blamed for you being run off location, getting kick from formation or next World War… My goal is simply to help people with their work and maybe actually save someone’s ass and money, because I know that life on rig can be hard…

What is more, since as much as I would like to check those calculations in every possible scenario please report in comments what problems you have encountered and what calculation differences you got and why. Thanks to that, I will be able to write additional methods or maybe slightly change them in order to match yours. In future I am planning to start a website where we could discuss these problems and maybe create such calculators for desktop computers!
