Abstract
One type of light weight cement is foam cement which can be used in cementing operations in weak zones with the possibility of small fractures, and reducing the amount of light weight cement suspension levels. The foam cement suspension can be used to solve lost circulation due to natural vertical fractures or cavernous formations. The purpose of this study was to determine the potential of foam cement slurry to solve the loss circulation in geothermal wells Making slurry cement uses class G cement at 200 mesh and 100 mesh sizes with the composition of Cement. The cement is put into the waring blender containing water, stir it for 35 seconds, adding foam agent into cement slurry with variations in foam agent concentration of 0.03%, 0.06%, 0.09%, 0.12% and 0.15%. Observation of foam cement slurry above was carried out for 30 minutes to test the stability of bubbles in the mixture. The results this study showed different compressive strength values at variations of the concentration of foam agent. The strength value is strongly influenced by evaluation of permeability, porosity and bulk density of core foam cement. The test results of samples with 0.03% Sika-aer concentration have a compressive strength value of 3745,533 psia, while samples with Sika-aer concentration of 0.15% have compressive value of 1701.459 psia The value of compressive strength core foam cement samples can form a linear line relationship between variations in foam agent concentration.
