Surface rights on lease

Looking over old leases of my Dads he only owned minerals not surface . Is it necessary To have all the surface rights in the lease which are in his leases My Dad owned minerals in Harrison and Marion co West Virginia now I own them

No, the mineral rights and surface rights can be severed. The mineral rights can be leased for drilling. The surface rights can be leased for the area needed on the topside for the rig and mud pits, etc. Independent.
