Abstract: A drilling fluid includes an aqueous base fluid; 1 to 30 wt. % of an okra composition; 10 wt. % of clay particles; and 0.005 to 0.5 wt. % of a base, each wt. % based on a total weight of the drilling fluid composition. The okra composition is uniformly disposed on surfaces of the clay particles. The clay particles disposed with the okra composition are present in the drilling fluid composition in the form of a composite. A pellet made from the clay particles treated with the okra composition has a swelling value at least 75% less than a swelling value of the pellet in an aqueous composition that does not contain the okra composition, as determined by a linear swell meter. A method of making the drilling fluid composition.
