Abstract

Drilling mud filtration plays an important role in maintaining wellbore stability and preventing excessive fluid loss during the drilling process. If uncontrolled, filtration can damage formations and disrupt operations. This study discusses the effectiveness of High-Pressure Water-Based Mud (HPWBM) with the addition of CaCo3 and Fracseal as an effort to reduce filtration and form a good mud cake. The purpose of this study is to evaluate the filtration performance of HPWBM in various well sizes under HighPressure High-Temperature (HPHT) conditions. This test was conducted in accordance with API standards ( 10 ml/30 minutes). The results show that the filtration rate for the 26“ trajectory is 4.6 ml/30 minutes, the 17-1/2” trajectory is 3.8 ml/30 minutes, the 12-1/4“ trajectory is 4.0 ml/30 minutes, and the 8-1/2” trajectory is 2.4 ml/30 minutes. All values were below the API limit, with a decreasing trend at greater depths. This study confirms that HOWBM with CaCo3 and Fracseal can control filtration, maintain well stability, and improve drilling efficiency and safety.

Abstract

This study aims to analyze the impact of glycerol additives on the thermal stability of carrageenan biopolymers from Eucheuma cottonii at a salinity of 5000 ppm and a temperature of 60 °C, which serves as a simulation for Enhanced Oil Recovery (EOR) reservoirs. Carrageenan solutions were designed with varying glycerol concentrations, then tested for viscosity at room temperature and after heating using a viscometer. The results showed that the addition of glycerol had a significant effect on viscosity stability. The idea glycerol concentration was able to reduce the decrease in viscosity caused by heating, while too much glycerol actually reduced the effectiveness of the polymer due to its plasticizer effect. This study recommends the use of glycerol at an optimal concentration to improve the thermal stability of carrageenan as an environmentally friendly biopolymer alternative for EOR applications with a salinity level of 5000 ppm.

Abstract

Squeeze cementing is a secondary cementing method used to overcome loss circulation problems and improve well integrity. This study aims to evaluate the squeeze cementing design in the “TOKAI” well, “PALMA” field using the bradenhead method. The methodology includes well data analysis, cement slurry requirement calculations, and evaluation of job performance based on pressure testing. The bradenhead method was selected due to its operational simplicity and because it does not require a packer. The calculation results indicate that 44 sacks of cement are required to produce 9.02 bbl of slurry, including a 2 bbl squeeze volume. The evaluation shows that the squeeze cementing operation was successful, indicated by a stable positive pressure test and the presence of fluid return. This method is proven effective in isolating perforation zones experiencing loss circulation.
