The kick is a prevalent problem related to drilling operations. Therefore, to reduce the likelihood of a blowout, it is essential to identify the kick as quickly as possible. Using a kick detection technique that depends mainly on monitoring surface parameters, there is a high likelihood of kick detection delay in addition to other problems. Techniques for down-hole monitoring may be capable of recognizing a kick in its early stages. Based on relative variations in the fluid's down-hole conductivity and flow rate, this study evaluates the occurrence of a kick. Moreover, there is provided a method to identify a kick without raising false alarms. In addition to, the variables most sensitive to formation fluid. In order to monitor the down hole parameters, three different instruments are used: density meter, the conductivity sensor, the Coriolis flow and the pressure transmitter. These results are place to use to evaluate the likelihood of the kick and risk of an associated blowout. The accurate interpretation of kick occurrence may be improved by monitoring a variety of down-hole data, which also greatly reduces on false alarms and gives a comprehensive view of down-hole situations. The kick detection time may be minimized by using down-hole monitoring methods. Well NR-C was selected to study the problem of the kick in Nahr Umr field. The result shown that the electrical conductivity reduced to 40 µs/cm when kick occurs and represents the best method to early kick detection combined with mud density.
