All petroleum in the UK and UK continental shelf (see ¶795-050) is in the ownership of the Crown. The Crown’s right to landward (onshore) oil was established in the Petroleum (Production) Act 1934. The Geneva Convention of the High Seas of 29 April 1958 established the UK’s sovereign rights to exploit the mineral resources of its continental shelf. This convention was ratified by the UK in 1964 and given effect to in UK law by the Continental Shelf Act 1964. This Act vested all the UK’s rights to seaward (offshore) oil reserves in the Crown and applied the Petroleum (Production) Act 1934 to those reserves.
