Abstract
Waiting on cement in the cementing operation of geothermal
wells is usually conducted from 8 hours to 24 hours after
displacement of cement into an annulus of casing. After that,
the quality of cement is evaluated using the CBL (Cement
Bond Log) test. Evaluation results of the compressive
strength and shear bond strength that is interpreted at 24
hours does not reflect the final strength of the cement.
The laboratory experiment for 7-day measurement indicated
that extending additives to API class G cement could
increase the compressive strength and shear bond strength of
cement immediately for about 3 days. After that the
compressive strength slightly changed or stable until the
seventh day, whereas the shear bond strength still increased
in lower level.
The experiment was carried out at a temperature of 150
o
C
dan pressure 2000 psi in a curing chamber that was
contaminated with formation fluid of the Kamojang Field.
