Abstract | One of the most important drilling operations is oil well cementing. Oil well can make stability of the wells, block fluid between lower and upper portion, and zeal off loss circulation zones. Properties such as thickening time, compressive strength, and porosity are the first priority which needs to be found out for cement job. To simulate oil well cement properties in real well conditions, well temperature and pressure are required for the test. The properties of oil well cement directly depend on the additives mixed. In this study, three different additives mixed in cement slurry were tested (33 tests in total). Three kinds of measurement were conducted, 27 tests of resistivity, 3 tests of pore water conductivity, and 3 tests of Ultrasonic Cement Analyzer (UCA). The tests were carried out under two main conditions, HP and HPHT. The relationships between resistivity, compressive strength, and porosity were investigated. The study results showed that different additives mixed in cementslurry yielded different results in resistivity, compressive strength, and porosity at the same testing conditions. Moreover, the resistivity measurement could assist the traditional method (UCA) in assessment oil well cement properties if a proper cementrecipe can be successfully designed and setup for high pressure and high temperature (HPHT) conditions. |
