A portable workover simulation training system is the combination of petroleum engineering and computer technology, virtual realization technology, computer simulation technology.

It is mainly used to train new workers, driller/ assistant driller, drilling technicians and driller supervisors. The training provided by this system can enable trainees to master the basic techniques of shutting in and well killing.

The system adopts a mathematical model to simulate various parameters such as pressure, torque, drilling rate, flow rate, etc., and to reflect the relationships between these parameters so as to reach the same effect as the real drilling operation. 3D animation in real-time makes up an immersive environment for the trainees.

  • What well control simulations does this well control simulator cover?

In well control operation, pressure control is very important. How the pressure is controlled? In the well control simulator, various scenes of kick can be simulated, both hard and soft shut-in the procedure can be carried out. Meanwhile, various well-killing methods are provided, such as driller’s method, engineer’s method, volumetric method, bullheaded, low choke method, standpipe pressure method, etc.


  • What new petroleum simulations and features are you working on?

Esimtech has been committed in the study and developing petroleum engineering simulation training system for about 30 years, and has a series of independent intellectual property rights. Our simulators are widely used in many training companies with good feedbacks. To keep pace with the international standard and demand, Esimtech is now studying and developing MPD simulator, where some achievement has been reached.


  • Can this simulator replace the simulators I currently use in my well control training program?

Esimtech drilling and well control simulator has been approved by IADC and IWCF which can be used for common operation training, as well as IWCF and IADC training programs.
