Before performing the cementing on the field , it is necessary to analyze the semen samples in the laboratory test beforehand to determine whether the cement composition according to circumstances on the ground or not . In this case , analyze two samples of cement with different brands , namely the brand " A " and the brand "B " but the same stage of testing . In this test samples with the brand "A" which is used to simulate the conditions in the well " X " field " Y " .
Analysis of sample tests of cement (cement density, rheology of cement suspensions, thickening time, free water, and filtration loss) by using a predefined way. Testing the density of cement by comparing the weight of the cement slurry (cement, water and additive) with volume of cement slurry. Testing of cement suspension rheology (plastic viscosity and yield point) by using a Fann VG Meter to see the scale readout on a rotor speed of 600 rpm and 300 rpm. Testing thickening time by using the tool Atmospheric Consistometer to see the scale of the instructions to the torque needle showed a price of 70 Bc. Free water testing using measuring tube, then filled the cement slurry of 250 ml and allowed to stand for 2 hours and record free water that occurred not more than 3,5ml. Testing filtration loss by using Filter Press, then fill the cylinder with cement suspension and N2 gas stream with a pressure of 1,000 psi after the record price at the 30 minute trial.
From the results of experiments in the laboratory then cement is used to simulate the conditions in the well " X " field " Y " is the brand "A" with a density of 15.8 ppg cement , plastic 45 cp viscosity , yield point 127 lb / 100ft2 , thickening time 16 uc ( Units of Consistency ) , free water and filtration loss of 0.5 ml 97.429 ml.
