## What is Wait and Weight Simulator?

This is a basic well control simulator for training that simulates the operations after the kick detection during the drilling operations in the oil well, but specific (ONLY) to practice the Wait and Weight Method, also named Engineer's Method.

This is a project based on app "Kick Game 2" available in our portfolio on the App Store.

Features:
1. Interface based on Hydraulic Choke Panel.
2. Graph in full screen (with background color in black or white) for analysis.
3. Pre-recorded data sheet
4. Vertical Wells: Surface (casing + open hole) and Subsea (riser + casing + open hole).
5. Drill String: Drill Pipe + Heavy Weight + Drill Collar.
6. Simulations with pause and panels with digital gauges. 
7. Method with Step by Step to turn the exercise easy to practice.
8. Like Kick Game App, just surface parameters are displayed.

Starting in version 2.0, this simulator can be used as a Remote Choke to control the app "Drilling Simulator 3, v4.0 or higher" when running on different nearby devices in a local access network (LAN).
