ANALISIS PENGARUH PENAMBAHAN BENTONITE TERHADAP SIFAT RHEOLOGI LUMPUR PEMBORAN MENGGUNAKAN POLYMER JENIS KCL (POTASSIUM CHLORIDE) PADA TEMPERATUR 100OF, 200OF, 250OF

Abstract

This study aims to analyze the effect of bentonite addition on the rheological properties of drilling mud using KCL (potassium chloride) polymer at temperatures of 100°F, 200°F, and 250°F. Drilling mud with bentonite and KCL polymer is important in the oil drilling industry because it affects well stability and drilling efficiency. The research method is qualitative with laboratory testing using a viscometer to measure rheological parameters such as plastic viscosity, yield point, and gel strength at various temperatures. The results showed that the addition of bentonite increased the rheological stability of the mud, especially at temperatures of 100°F and 200°F, with more optimal viscosity and gel strength values. However, at a temperature of 250°F the rheological performance decreased due to degradation of the KCL polymer and changes in the bentonite gel structure. The conclusion of this study states that the use of bentonite can improve the rheological properties of KCL-based mud at low to medium temperatures, but is less effective at high temperatures. This research provides important insights for more effective and stable drilling mud formulation in the field.
