Abstract

One of the critical factor of cementing operation is designing the cement slurry. For that reason, slurry properties which have been classified by American Petroleum Institute (API) should be changed so it will match the requirements of reservoir condition. Changing the slurry properties is done by adding the additives into the cement slurry. This research objective is to test the effect of calcium carbonate and silica fume to the oil well cement. The result of this research are the data of oil well cement physical properties, compressive strength and shear bond strength. The data are collected by making cylinder sample with 75 mm x 150 mm for the compressive strength specimen and cylinder with 1 inch x 2 inch (25.4 mm x 50.8 mm) for the shear bond strength specimen that will be tested on Shimadzu Universal Testing Machine, which is then the result of the test will be compared to the API standard and result from other researches. The specimen will have 5 variants percentage of silica fume and calcium carbonate (0% calcium carbonate (CC) + 0% silica fume (SF), 5% CC + 5% SF, 10% CC + 10% SF, 15% CC + 15% SF, and 20% CC + 20% SF) and 3 variants of cement age (7, 14, and 28 days). From the performance of cement with calcium carbonate and silica fume in the laboratory test, it can be concluded that by adding calcium carbonate with 5% or more into the cement slurry will reduce both compressive strength (22.253 MPa (0% CC + 0% SF), 19.803 MPa (5% CC + 5% SF), 12.963 MPa (10% CC + 10% SF), 10.264 MPa (15% CC + 15% SF), 9.526 MPa (20% CC + 20% SF)) and shear bond strength (3.139 MPa (0% CC + 0% SF), 6.849 MPa (5% CC + 5% SF), 3.695 MPa (10% CC + 10% SF), 3.065 MPa (15% CC + 15% SF), 2.596 MPa (20% CC + 20% SF)). The usage of silica fume is to reduce the loss of compressive strength caused by calcium carbonate, it can be seen in the comparison between the result of this research (19.803 MPa (5% CC + 5% SF)) and Paramatatya’s (2014) research (19.36 MPa (2.285% CC)) where the compressive strength of the specimen with 5% of calcium carbonate and 5% of silica fume has higher compressive strength compare to paramatatya’s sample with 2.285% of calcium carbonate.
