The RF kick simulator is a tool for well control engineering, study and training. The simulator accounts for all important physical effects related to a kick, and models kicks in both water based mud and oil based mud. In order to test the performance of the model, real gas kicks in both water based and oil based mud have been simulated. Surface and downhole data from full scale gas kick experiments have been used to verify the simulator. The data used are downhole annulus pressure data, surface pressures, mud flow rate out, pit gain and gas transport data. The measured gas influx rate into the well versus time has been used as input data to the gas kick simulations.

The conclusion of the comparisons is that the RF kick model reproduces real kick data with acceptable accuracy. This confirms the capability of the RF kick simulator to model gas kicks. The simulator can therefore be used with confidence for the design of well control procedures and the evaluation of kick situations.
