As a matter of Kansas public policy, all oil and gas leases and subleases for the exploration, development and production of oil, gas or other minerals, or any combination thereof, which are held by production shall be presumed to contain, in addition to any expressed covenants therein, an implied covenant to reasonably explore and to develop the minerals which are the subject of such lease. Such implied covenant shall be a burden upon the lessee and any successor in interest.
