## What is Wait and Weight Method?

This app is designed for both iPhone and iPad.

This application uses the basic calculations of the "Wait and Weight" 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, Kick Game, Kick Tolerance, LOT Simulator, MPD Simulator  and Well Control Simulator) available for sale in our portfolio on the App Store.

It is can be applied on the field and also help in the understanding of the "Wait and Weight" method for well control. 

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.

Thanks
