ESIM-FLS2 compound logging simulation training system is an advanced simulation training system used to provide training to operators, logging crew in training centers as well as petroleum colleges.

The system adopts a full-size logging equipment room, sand table well site model, sensor models, advanced logging software, drilling accidents modeling software and sensor detecting software designed in our own company. It presents the whole process of compound logging. Through the training of this system, students can master various operation skills and experience in treating drilling accidents.

  • What is a petroleum simulator?

A simulator is a device that simulates an environment for the purpose of training or research. A petroleum simulator is a set of devices that simulates the well site environment, the real operation devices, the operation method, parameter display way, etc. with which trainees can be access to a virtual well site environment, where they can get familiar with the relative devices, how to operate the devices, what phenomenon there will be if there is a problem, what’s happening underground, etc.


  • Why is the simulator necessary to oil and gas industry?

Since the beginning of the 20th century, simulators have been used in different industries as tools to train and to facilitate the growth of the operators of the machinery. This type of training is, without a doubt, one of the most effective ways to mitigate labor risks, develop skills needed, and increase productivity. 

In oil and gas industry, accidents happen from time to time, such as blowout, H2S leakage, fire, explosion, machinery injuries, etc. Working in oil and gas field is of high risk. According to statistics, almost 36% of these accidents were caused by mistake in operation. Sufficient pre-post training is essential. A simulator makes this possible, which provides a virtual training environment, for new staff the get familiar with the working environment, site scene, and operation devices in advance. With the simulator, new staff can also experience the common incidents which may occur in real operation, and learn to judge and handle the emergencies. So that in real work, most of the accidents can be a judge or avoid in an early stage, and therefore reduces risks and increase production.


  • 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 good control simulator, various scenes of kick can be simulated, both hard and soft shut-in 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.
