摘要

The study focused on the preparation of carbonaceous material supported TiO2 composite using a hydrothermal technique, and its application as a shale inhibitor in water-based mud (WBM). The activated carbon/anatase-TiO2 (AC/TiO2) nanoparticles were synthesized using orange peel powder, which was then serve as a supported for anatase-TiO2 nanoparticles. The shale swelling mitigating characteristics of AC/TiO2 composites was also compared with sodium alginate; a biopolymer obtained from brown algae. The result of the study reveals that the AC/TiO2 composites were highly effective and played a pivotal role in inhibiting the shale swelling behavior. As the concentration of AC/TiO2 composites increases in WBM, a significant reduction in swelling was recorded in linear dynamic swell-meter experiment. A minimum of 5.8% was recorded when 3.50 g of AC/TiO2 composites was used in WBM. In contrast, 5.25 g of sodium alginate was also required to achieve the same shale swelling. This finding was also in good agreement with the ANOVA analysis, where AC/TiO2 composites demonstrated \(\:\:p-value\:<\:0.05\) confirming its statistical significance. Additionally, the predicted model generated by the CCD method performed efficiently at higher AC/TiO2 concentration, showing good agreement between the model and the experimental results for samples containing higher weight of AC/TiO2 composites.
