Shale instability in shale gas drilling can cause significant disruptions, including wellbore failure and operational inefficiencies, making it a key issue that demands innovative solutions for smoother and more cost-effective drilling processes.

Overall CA NADES improved YP/PV and resulted into 42.8%, 40.32% and 76.1% decline in mudcake thickness, filtrate volume and linear swelling respectively with 51.68% improved shale recovery.

摘要

Shale instability in shale gas drilling can cause significant disruptions, including wellbore failure and operational inefficiencies, making it a key issue that demands innovative solutions for smoother and more cost-effective drilling processes. Various additives including Potassium Chloride (KCl), 1-Ethyl-3-methylimidazolium chloride. ([EMIM]Cl), SiO2 nanoparticles, amine terminated polyetheramine (ATPE), Okra mucilage, Choline Chloride:Urea Deep Eutectic Solvent (DES), and Citric acid:Glycerine Natural Deep Eutectic Solvent (CA NADES) and their combinations were subjected to rigorous examination to delineate their impact on shale stability and drilling fluid properties. Overall CA NADES improved YP/PV and resulted into 42.8%, 40.32% and 76.1% decline in mudcake thickness, filtrate volume and linear swelling respectively with 51.68% improved shale recovery. Moreover, SET B (0.5% KCl + 0.5% ATPE), and SET G(0.5% KCl + 0.5% [EMIM]Cl) emerged as particularly promising candidates for ameliorating shale swelling and enhancing drilling fluid properties. In conclusion, this study underscores the pivotal role of additives in assuaging shale instability and optimizing drilling fluid formulations. The elucidation of additive efficacy in mitigating shale instability and optimizing drilling fluid performance holds profound implications for real-world drilling operations, promising enhanced efficiency, and reliability in the extraction of vital subsurface resources.
