T The purpose of squeeze cementing job in RA-1 and RA-2 well is to repair the result of bad bonding cement wall on the 7” production casing. The zone whom has the bad quality of cement in those well located at the productive zone, that why there must be a repairmen to prevent the productive zone mixing into the other non productive zone. To informing the interval that need to be repaired Log CBL is commonly used, therefore who already knowed that in the reading of CBL the interval of the RA-1 well is 1450 – 2106 ft(656 ft) and at the RA-2 well is 200 ft – 542 ft (342 ft). From the CBL reading data we can also knowing the volume of the cement that need to use in this squeeze cementing job. Before the squeeze cementing job, there need to do an injectivity test and also communication test that needed to knowing the estimate rate of injection when the squeeze job applied and also to testing a possibility of channeling behind the wall of the cement. The injectivity test result is informing that the RA-1 well isn’t have any loss or communication problem in the wall of the cement, but there’s a different condition in RA-2 wells whom have a indication of loss and channeling in the bonding of the cement. The treatment that were applied at the squeeze cementing job in those two wells were using different treatment where the RA-1 well isn’t used any packer in the squeeze, but the RA-2 well is use a packer and the result is different too. In RA-1 the squeeze isn’t effective because the amplitude of the CBL reading is still high, but in the RA-2 well is effective because the amplitude of CBL reading is low.
