How to transfer Deed & Lease

My uncle and i each own 50% of my late grandmothers mineral interest in blaine and kingfisher county. My mother and uncle inherited the interest after my grandmother past in 1997, and i inherited my mothers interest when she past in 2010. All the current operators have their records updated with our names and owner numbers but the original Deed and Lease are still in my grandmothers name. We've found a deed and lease for 1 of 5 properties. How do we go about getting them updated? How can i find a good oil and gas attorney to help us. Thanks.
