... (FL), and filter cake thickness (FCT). Their small particle size, excellent material dispersion, and thermal stability are the reasons behind the usage of GNPs in drilling fluid. Here, GNP from Kenaf stem was synthesized, and its surface was modified with nonionic surfactant triton-X100 to improve its...

... Abstract Unstable wellbore often occurs in water-sensitive shale formations during drilling, leading to longer drilling times and higher costs. This problem has been addressed by using various shale stabilizers for water-based muds (WBMs) such as polymers, salts like potassium chloride (KCl...
