Abstract

Problems in the form of water entering the production well in one of the formation zones can result in a significant. increase in water cut so it is necessary to do a water shut off, namely using squeeze cementing as one solution, determining the right method for squeeze cementing work needs to be done based on the characteristics of the formation in the well, so that the squeeze cementing work can run well, determining the right method can be done by evaluating the results of the injectivity test along with other supporting data such as reservoir properties data. This study has the aim of analyzing the results of injection testing carried out before the squeeze cementing work, the data obtained is evaluated with other data in the form of well data in the form of reservoir properties and also slurry cement data, based on the evaluation, the method used is determined by the combination of the hesitate method with the balanced technique plug at intervals M4 6181-6195 ft, in the next evaluation 49.31 sacks of slurry cement were used using grade G cement material with additives added in the form of BZP 101 – Defoamer 0.10 gps concentration, BZR 101 – Retarder 0.09 gps concentration and BZF 101 - Fluid Loss Control Agent concentration 0.39 gps
