Abstract

The success of a drilling operation depends on the conditions and mud system used. Changes in the physical properties of the mud are caused by contamination from NaCl, which occurs when drilling penetrates a high-salt dome and enters the drilling mud.The purpose of this research is to investigate the effect of adding Bentonite and Attapulgite additives on the properties of drilling mud. This research uses an experimental method.The results show that the density of the mud remains constant in the range of 1.04-1.06 ppg, even when Attapulgite is added up to 4 grams, because the use of barite remains at 25 grams. The addition of Attapulgite increases the plastic viscosity from 13 cp in sample 1 to 24 cp in sample 5, increases the yield point from 30 lb/100ft² to 62 lb/100ft², making the mud more effective in transporting drill cuttings. The gel strength increases from 11 lb/100ft² to 15 lb/100ft², meeting API standards. The filtrate decreases from 8.4 mL in sample 3 to 6.6 mL in sample 5, indicating Attapulgite's ability to control filtration. The mud cake thickness remains thin (0.13-0.18 mm), in accordance with API standards. Conclusion The addition of Attapulgite in the amount of 1-4 grams shows an increase in various parameters. Attapulgite is effective as an additive for controlling filtration loss, with test results showing a decrease in filtrate volume in all samples.

Abstract

In drilling operations, mud planning is one of the most important factors in supporting the success of drilling operations in oil wells. Planning for the use of drilling mud is used for maximum results in cutting and maintaining drilling wells. This study aims to determine the cause of swelling and what problems will be caused if swelling control is carried out less than optimally. In this study, we analyze the mud that will be used in drilling operations, so that it can prevent or minimize swelling of clay in the shale system by adjusting the polyamine content to be used. After doing the research, it was found that at the "X" well there was no swelling in each route because each route was dominated by alkaline mud which had a pH above 7 then the total polyamine used for the mud system in the "X" well was as much as 3654,903 gal with a concentration of 1.5%
