The Petroleum (Production) Act 1934 (24 & 25 Geo. 5 ch. 36) is an Act of the Parliament of the United Kingdom which clarified the ownership of underground petroleum, vesting it in the Crown. It made provision for searching and boring for and getting (producing) petroleum and natural gas, under appropriate licenses. Background Before 1934 there was a lack of clarity about the ownership of oil beneath a property. For example, in 1919 the Attorney-General was asked in Parliament whether the surface owner also owned the oil beneath their land. The Attorney-General acknowledged that opinions differed, but was inclined to the view that the surface owner is the owner of oil beneath the land. The 1934 Act clarified the position and vested underground oil in the Crown. The Petroleum (Production) Act 1918 had required persons wishing to prospect for oil to obtain a license from the Board of Trade. However between 1918 and 1934 only seven licenses were issued and by 1934 only three were in force. Furthermore, oil prices were generally falling during the 1920s thereby discouraging exploration.
