Introduction
Home
Well Control Simulator for iPhone and iPod Touch
Well Control Simulator Provides a graphical very useful tool for training of roughnecks, derrickmen, drillers, tool pushers, drilling
engineers and students in the well control procedures.
-
Interactive System: no pre-set methods;
Ability to apply methods: Driller's method, wait and weight, dynamic volumetric and static volumetric (lubricate and bleed);
Capacities and Volumes;
Hydraulics and Hydrostatics and critical pressures calculations;
Behavior of the kick;
Applied with subsea stack and surface stack;
Kick Model:
The model assumes that the kick starts as a single bubble and migrates upward as a single bubble from the bottom to the surface.
Note: This simulator is limited by project and is not applied to more complex situations.

Opening a Data File
When TAP on “Open” button, the data that is on the Data
File Highlighted on Wheel is loaded in the RAM memory
and can be saved with other file name.
Method to transfer data file between iCloud and Local:
The user can open a data file on Local (On My Device)
and after save it on iCloud or the opposite.
iCloud Message:
On the first time that the user taps on “Open” button, the
download of the data file is started from the iCloud to a local
address with internal access only. When the download is
completed, it’s possible open the data file.
The user must tap again on the “Open” button for checking.
When OK, the data file is loaded in RAM memory and shown
on the well schematic.

Menu

About the Surface Circulation Volume (SCV):
Surface Circulation Volume = Volume of the flow line, pipes, etc
when circulating at the surface.
When occur a kick on the drilling, the driller stops the mud pump and
the "Surface Circulation Volume" return to tank.
The calculation of the real volume of the kick = Static Vol. after shut-in
the well - Dynamic Volume on drilling - Surface Circulation Volume.
