R-covered foliations provide a natural geometric implication for the left-orderability of 3-manifold groups from taut foliations. In this talk, I will describe some constructions of R-covered foliations obtained by Dehn surgeries. I will focus on examples of such constructions in Dehn surgeries on the (-2, 3, 2q+1)-pretzel knot K with rational slopes less than 2g(K) - 1, for q greater than or equal to 3.
