The Wait and Weight Method (also named Engineer's Method) for Mac provides to drillers, tool pushers, engineers, chemists, students and other professionals in the petroleum industry a productivity tool helpful in drilling of oil wells and in the understanding of the wait and weight method of well control.
It is an useful tool to import data files from our apps for OS X and iOS (Driling Hydraulics and Kick Tolerance) and also for iOS (Drilling Simulator 1 and 2, Kick Game, LOT Simulator and Well Control Simulator 1 and 2) available for sale in our portfolio on the App Store.
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 land rigs.
This version is completely interactive and allows users to define a wide variety of parameters for oil wells and unit system, save data and more.
1) Calculations of Riser Safety Margin;
2) Included the formulas;
3) Ability to work with files on iCloud and on Mac;
4) Pop-up view to alert user about invalid values;
5) Ability to move drill string and position of kick off the bottom;
6) Views with calculations of hydrostatics, capacities, volumes and more.
7) Defining the parameters of the well, drill string, drill bit, mud (fluid), mud pumps, circulation lines on surface, diameter and coefficient of choke and more;
8) Options wells in floating units or in drilling land rigs;
9) Choice of rheological models (Bingham and Power);
10) Calculation of the ECD on bottom hole and the casing shoe;
11) Hydrostatic calculations at the bottom hole and the casing shoe;
12) Selecting the system of units. Select per parameter, too.
15) Drill string sections: Drill pipe 1, Drill pipe 2, Heavy weight, drill collar 1 and drill collar 2.
16) Included Qty / Size of Jet Nozzles;
17) Option for Bit TFA fixed;
18) View for Internal pipe and Annulus friction losses and hydrostatic calculations.
19) Directional basics Hydrostatic calculations (KOP, Bottom Hole and Casing Shoe TVD and Measured Depth)
20) Summary of method.
21) Optimized for horizontal and directional wells.
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.
