Abstract

P enggunaan aditif pada semen merupakan hal yang biasa dilakukan dalamoperasi penyemenan suatu sumur baik sumur minyak, gas, maupun panas bumi.Tugas akhir ini menjelaskan hasil studi laboratorium tentang perbandinganCompressive Strength dan Thickening Time semen kelas G yang ditambahkanaditif Lignosulfonate, Sodium Borate dan CMHEC. Diketahui bahwaLignosulfonate, Sodium Borate dan CMHEC merupakan aditif retarder. Tujuandari penambahan Lignosulfonate, Sodium Borate, dan CMHEC adalah untukmemperbesar Thickening Time bubur semen. Artinya dengan ditambahkannyaLignosulfonate, Sodium Borate, dan CMHEC maka seharusnya bubur semen akanmenjadi lebih lama mencapai konsistensi sebesar 100 UC.Studi laboratorium dilakukan untuk melihat sejauh mana efek penambahanjenis aditif yang telah disebutkan sebelumnya dengan tiga temperaturpengkondisian yang berbeda yaitu 80Â°F, 140Â°F, dan 180Â°F, dan dengan waktupengkondisian (curing time) selama 24 jam

T he use of additives in cement is a common thing to do in a well, oil well,gas well, or geothermal cementing operating. For cementing operations support,surely we should know the physical properties of additive on cement when added.This final task is to explain the difference of results that studies on theCompressive Strength and Thickening Time of class G cement with additives suchLignosulfonate, Sodium Borate dan CMHEC. Note that Lignosulfonate, SodiumBorate dan CMHEC are retarder additive that is able to enlarge the thickeningtime of cement. While barite is one of the most common weighting agents used asa mix of drilling mud or cement. The purpose of the addition of barite is toincrease the density of the cement slurry. This means that, with the increase ofadditive content, the cement slurry will delay the reach of 100 UC.Laboratory studies conducted to see the extent to which the effects of theaddition of the type of additive already mentioned before with three differentconditioning temperature which is 80Â°F, 140Â°F, and 180Â°F, and with the curingtime of 24 hours.
