Drilling Simulator 2 – Optimized for horizontal and directional wells

Drilling Simulator 2

Drilling with Well Control

Optimized for iPad Pro and iPhone 6 Plus

Version 1.2 – Optimized for horizontal and directional wells

This is a basic drilling simulator that simulates drilling operations based in panels for kick detection, shut-in the well, stabilization of pressures and the choke operations during the well control operations using a hydraulic choke panel simulator.

This is a new project based on apps “Drilling Simulator” and “Well Control Simulator” available in our portfolio on the App Store.

Additional features:
1. Driller Interface based on Pressure Gauge, Weight Indicator, Rotary Torque gauge and Geolograph.
2. Choke Interface based on Hydraulic Choke Panel.
3. Graph in full screen (with background color in black or white) for analysis.
4. Pre-recorded data form
5. Three codes (admin, instructor, student) to view the gas into the borehole, the pressure at bottom, at shoe and at bop and to enable / disable the Lag Time (by adjusting the choke to change the kill pressure and drill pipe pressure, etc).

Other features also available:

A graphical very useful tool for training of roughnecks, derrickman, drillers, toolpusher, drilling engineers and students in the well control procedures.

– Ability to drilling, kick detection, shut-in, stabilisation of pressures;
– Interactive System: no pre-set methods;
– Ability to apply control methods: Driller’s method, wait and weight, dynamic volumetric and static volumetric (lubricate and bleed);
– Hydraulics and Hydrostatics;
– Behavior of the kick;
– Applied with subsea stack or surface stack;
– Set well with until 4 sections: riser, casing, liner, open hole ;
– Set Drillstring with drillpipe1, drillpipe2, heavy weight, drillcollar1, drillcollar2

Notes:
Others apps very useful of our portfolio for Well Control:

– Drilling Hydraulics
– Kick Tolerance
– Leak-Off Test Simulator
– Leak-Off Test Analyzer
– Well Control Methods
– Well Control Worksheets
– MPD Simulator
These tools can complement (work with) this simulator by creating files which can be used in this application;

– This simulator is limited and is not applied to some complex situations.

Well Control – Initial Circulating Pressure on deepwater

On deepwater drilling, the subsea bop stack is installed at the well head (on sea bed). In kick condition, the BOP is closed and the flux is deviated to the choke at surface through the choke line. This line has a diameter normally of 3 inches and the frictional pressure losses will increase the pressure at shoe depth. This is a big problem on deepwater wells due to the formation pressure be fragile.

A method to compensate the choke line friction is to decrease the initial choke pressure of this value, monitoring the annulus pressure at the kill pressure gauge instead the choke pressure gauge when bringing the mud pump to slow circulation rate, like on a surface bop well control, and adjusting the choke to set the drill pipe pressure equal to the Initial Circulating Pressure (ICP) calculated by the formula ICP = SIDPP (Shut-in Drill Pipe Pressure) + Pump Pressure @ slow circulating rate when circulating through the drill string with return to the riser.

Some questions:

Why to use the pump pressure with return to the riser if the circulation of the kick is with return to the choke?
Why to set the choke fully open during the circulation to record the choke line friction?
etc.

The answers for these questions are in the calculations in the next slides.
