Abstract
The present disclosure relates drilling fluids and methods of producing and using drilling fluids. The drilling fluid include an aqueous base fluid; at least one of a clay-based component and a mud; and a shale inhibitor comprising silica grafted with glutamate-glycol, wherein the drilling fluid does not comprise KCl, has a shale cutting rate from 65% to 99%, and has an anti-swelling capacity from 55% to 99%. The method of using the drilling fluid in drilling operations includes mixing an aqueous base fluid, a shale inhibitor comprising silica grafted with glutamate-glycol, and at least one of a clay material and a mud to produce a drilling fluid; and introducing the drilling fluid to a subsurface formation, wherein the drilling fluid does not comprise KCl, has a shale cutting recovery rate from 65% to 99%, and has an anti-swelling capacity from 55% to 99%.
