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.
