Driller's Method vs TallyRig

This app is designed for both iPhone and iPad. This application uses the basic calculations of the Driller's Method to control oil wells after the occurrence of kick during drilling operations on floating platforms and landing rigs. It is an useful tool to import data files to fill kill sheets from our apps: (Driling Hydraulics, Drilling Simulator 1, 2 and 3, MPD Simulator, Kick Game, Kick Tolerance, LOT Simulator and Well Control Simulator 1 and 2) available for sale in our portfolio on the App Store. It is can be applied on the oilfield (see Disclaimer) and also to help in the understanding of the Driller's Method. This app was developed based on existing spreadsheets. There is no comparison with any other software. Our goal was to create a low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. There is no intention to replace the professional softwares. You can contribute with suggestions for improvements, correcting the translation to english, reporting bugs and spreading it to your friends.
