A drilling fluid composition includes an aqueous base fluid, 0.01 to 10 wt. % of a date palm leaves extract (DPLE), 1 to 10 wt. % of clay particles, and 0.01 to 1 wt. % of a base, where each wt. % based on a total weight of the drilling fluid composition. The DPLE is homogenously disposed on surfaces of the clay particles. The clay particles disposed with the DPLE are present in the drilling fluid composition in the form of a composite. A pellet made from the clay particles treated with the DPLE has a swelling value at least 75% less than a swelling value of the pellet in an aqueous composition that does not contain the DLPE.
