Abstract
Drilling a deep well is one of the most serious duties that we face in the petroleum industry because of the possibility of well kicking whatever it is a gas or liquid kick. Kick represents the most dangerous situation that can occur during drilling a deep well, since it can easily develop into a blow-out. Thus, well drilling today is a potential ”blowout” . So it becomes necessary to select a suitable method to kill the flowing well without formation fracturing. This research will help in choosing the suitable killing method, Thus it should be used during well control of vertical and deviated wells. The optimum method used for killing a flowing well should produce the lowest pressure on the weak point at casing shoe, Taking in consideration the amount of chemicals used and the time of mixing killing mud that can effect on the pressure during killing operation. So, by studying four actual cases of deep wells in different concessions in Egypt, It was used simulator runs to obtain the following results in this research. The first result is that the wait and weight method is suitable for killing a deep well with a long open hole section volume. Thus, this has twice or more string capacity volume due to decreasing casing pressure at casing shoe “weak point” than driller method. The second result is that the driller method is suitable for killing a deep well with chemical on board. This is enough for only one complete cycle to get out the influx and secure the well. The third result is that the driller method is suitable for killing a deep well. If the mixing time of kill mud weight is more than the gas migration rate. The fourth result is that the driller method is suitable for killing a deep well. If the open hole section volume is less than string capacity volume. The validity of these results was checked by comparing the pressures results during killing operation for each method on simulator run for four actual cases in different concessions in Egypt.
