Pore space-severances and separate conveyances prohibited.

This Wyoming bill (SF 43) prohibits separating and selling ownership of subsurface pore space (empty spaces in rock formations holding oil, gas, or water) from surface land ownership after July 1, 2024. It allows existing severed pore space rights (transferred before July 1, 2024) to continue being conveyed, but requires clear descriptions of the subsurface location for any transfers between 2008 and 2024 to be valid. The law grandfathered pre-2008 contracts and pre-2024 severed rights, meaning they remain enforceable. The bill failed committee introduction on February 13, 2024 (10-21 vote) and will not become law.
