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.

Abstract

Real-time information on subsurface characteristics is crucial in oil and gas drilling activities to reduce risks and improve operational efficiency. One widely used method is logging, including the Spectral Gamma Ray (SGR) technique, which functions to identify formation types and natural radioactive content. The integration of SGR in Mud Logging allows for more accurate formation monitoring during drilling. The development of Advanced Mud Logging (AML) further strengthens this capability through Cutting analysis, thus producing more comprehensive Petrophysical Information Logs (PILs) as a basis for well evaluation. This study analyzes the application of SGR technology in the AML system in drilling Well C in Field W, with a focus on improving the accuracy and efficiency of subsurface formation characterization. Research data were obtained from gamma radiation measurements on Cutting and further analysis using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). Primary data comes from field measurements and laboratory analysis, while secondary data is obtained from related literature. The results show that SGR is able to provide real-time formation mapping with higher accuracy than conventional methods, while reducing ambiguity in lithology and stratigraphy interpretation. Comparison with Measurement While Drilling (MWD) data demonstrated a high degree of agreement, supporting the validity of this technology. Overall, this research contributes to the development of more efficient, responsive, and accurate drilling monitoring systems
