US Patent 11912926 Synthetic functionalized additives, methods of synthesizing, and methods of use

Synthetic functionalized additives may comprise a layered magnesium silicate. The layered magnesium silicate may comprise a first functionalized silicate layer comprising a first tetrahedral silicate layer covalently bonded to at least two different functional groups, an octahedral brucite layer, and a second functionalized silicate layer comprising a second tetrahedral silicate layer covalently bonded to at least two different functional groups. A drilling fluid may comprise the synthetic functionalized additive.
