Mitigating Shale Swelling by Using Pomelo Peel Powder and Activated Carbon Prepare from Waste Material in Pakistan Shale Formation

Abstract The research highlight an eco-friendly method to prevent shale swelling during drilling,with a focus on evaluating the effectiveness of pomelo peel powder and activated carbon prepare fromwaste material as potential additives to drilling fluids in Pakistan shale formation. Optimizing the inhibition of selected drilling fluid. Various experiments,including immersion test, determination of contact angle, determine rheological properties, filtration loss,hydration inhibition, dynamic linear expansion of bentonite, LDSM and quality control, UV test and withoutUV test are conducted to study the effectiveness in preventing shale swelling. Equipment like mortargrinder, sieve shaker, pH meter, heating oven and hydraulic compactor and ImageJ software for analysisare used. Pomelo peel powder and Activated carbon are considered aspotential additives to water-based drilling fluids. The results indicate that mass fraction solution of pomelopeel powder with optimized particle size can effectively reduce shale collapse and mud loss by filtration.While activated carbon directly purifying water won't prevent swelling, using purified water with lowerimpurity levels can contribute to a more stable drilling process, it reduces the risk of clay swelling. Pomelopeel powder improve the rheological properties of drilling mud. Activated carbon can adsorb variousorganic and inorganic compounds. Pomelo peel powder and Activated carbon both are eco and environmental friendly. This paper presents novel findings on the potential of Lady Pomelo peel asa clay swelling inhibitor in water-based drilling muds. It contributes to the existing literature bydemonstrating its inhibitory properties, improving drilling mud characteristics, and offering anenvironmentally friendly alternative for clay swelling inhibition. These insights support the petroleum industry's pursuit of sustainable and eco-friendly drilling practices.
