Abstract

The formation of wax crystals in crude oil at low temperatures can increase viscosity and block flow, making the use of chemical pour point depressants (PPD) necessary. This study aimed to evaluate the effectiveness of PPD at a concentration of 150 ppm in lowering the pour point and to analyze the relationship between crude oil characteristics and pour point values. Testing was carried out on three crude oil samples from the Sangatta Field using standards ATM D1298 (API Gravity), ASTM D4007 (BSS&W), ASTM D445 (viscosity), and ASTM D97 (pour point). The results showed that samples with lower API Gravity, and higher viscosity and BS&W, had higher pour points. Adding 150 ppm lowered the pour point of sample XY from 23°C to 11°C, YY from 24°C to 13°C, and ZY from 26°C to 19°C. Using 150 ppm PPD is recommended as an option to improve crude oil flow under low temperature conditions.

Abstract

This study analyzes the effect of adding borax (sodium tetraborate) as a retarder additive on both parameters, using concentration variations of 0%, 0.25%, 0.5%, and 1% BWOC at a fixed water-cement ratio of 0.44. Testing was performed with a hydraulic press after 24 hours of curing. Compressive strength rose from 654.2 psi (0%) to 1,122.3 psi (0.25%) and peaked at 1,421.1 psi at 0.5%, before dropping sharply to 525.6 psi at 1%. Shear bond strength followed a similar pattern: 144.5 psi (0%), 233.6 psi (0.25%), 295.7 psi (0.5%, the highest value), and 127.3 psi at 1%. A concentration of 0.5% BWOC proved to be the optimum point, while excess borax triggered over-retardation that hindered C-S-H formation and reduced cement strength

Abstract

Preparation of XCD solution using 2.50 g of XCD powder and 500 mL of distilled water mixed with a magnetic stirrer at a speed of 1000 rpm for XCD solution viscosity value is 18.15 cP and density of XCD solution is 1.875 g/mL. Injecting the XCD solution using a syringe pump in order to get a stable rate when pushing fluid from inside the sandpack, water flooding is done first to see the sealing power in the sandpack with a recovery factor obtained of 90%. With 250 mL of XCD solution injected, it can push out 31 mL of light oil trapped in the sandpack and get a recovery factor of 98% from the sandpack. Sweep efficiency of water and XCD flooding obtained is 0.89 where the mobility ratio value (M < 1) is very good sweep efficiency that works and if the mobility ratio (M > 1) sandpack conditions have been damaged such as water fingering in the sandpack.

Abstract

Effective porosity (PHIE) is a critical petrophysical parameter in reservoir evaluation, yet its conventional determination through core analysis is constrained by high costs and limited data coverage, particularly in heterogeneous reservoirs with nonlinear log relationships. This study analyzes the performance of three machine learning algorithms, namely K-Nearest Neighbor (K-NN), Random Forest (RF), and Gradient Boosting (GB), in predicting PHIE from well logging data (Gamma Ray, Bulk Density, Neutron Porosity, Sonic Transit Time) using Orange Data Mining, with a 75% training and 25% testing split validated through Stratified 10-Fold Cross Validation. Results show Gradient Boosting achieved the best performance (R² = 0.828; RMSE = 0.012; MAE = 0.008), followed by Random Forest (R² = 0.812) and K-NN (R² = 0.754). The sequential boosting mechanism proved more adaptive in capturing nonlinear relationships between log parameters and effective porosity, offering an efficient tool for formation evaluation with reduced reliance on core data.

Abstract

Cementing is an important stage in drilling operations that requires cement quality control to provide appropriate strength and setting time. This study aims to analyze the effect of adding alum additives on the mechanical properties and setting time of drilling cement. Tests were conducted using the Compressive Strength and Setting Time method with variations in alum concentration of 0%, 1%, 2%, 3%, and 4% BWOC. The results show that the Compressive Strength value increases with increasing alum concentration, from 538.294 psi in the base cement to 1,267.898 psi with the addition of 4% BWOC, all meeting the API minimum standard of 500 psi. The addition of alum also accelerates the Initial Setting Time from 315 minutes to 15 minutes and the Final Setting Time from 430 minutes to 45 minutes. Based on the results of the study, an alum concentration of 3% BWOC provides the most optimal performance because it produces a high increase in compressive strength with a setting time that is still suitable for well cementing applications.

Abstract

Wellbore instability caused by swelling clay represents a major technical challenge in drilling operations. This study aims to analyze and compare the effectiveness of Potassium Chloride (KCl) as an inorganic shale inhibitor and Polyamine as an organic polymer inhibitor in suppressing the swelling rate of reactive clay minerals. The experimental method was conducted in the laboratory using a Linear Swell Meter (LSM) for 24 hours with inhibitor concentration variations of 1%, 3%, and 5%. The test results indicated that KCl demonstrated significantly superior performance compared to Polyamine in controlling clay expansion. The final swelling value of KCl decreased significantly with increasing concentration, from 42.30% (1% concentration) to 22.35% (5% concentration), due to the ability of K+ ions to enter the interlayer space and suppress hydration. Conversely, Polyamine was less effective, with swelling values remaining high above 35% across all concentrations (35.89% at 5% concentration), as its mechanism is limited to surface encapsulation without optimally arresting crystal expansion. In conclusion, KCl at a 5% concentration provides the best formation stability and is highly recommended to minimize the risk of wellbore instability in reactive clay formations.
