Providing for BNOC and enhanced state control
This period of major and controversial legislation was also one of memorable exploration successes and fi eld developments. The remarkable volumes of reserves discovered and the large average size of discovery are shown in Appendices 8.1 and 8.2. The number of signifi cant discoveries was also notable (Appendix 8.3), while the exploration success rate (Appendix 8.4) was high by international standards. Expenditures on fi eld developments grew dramatically at this time, and in real terms attained their highest ever levels (Appendix 8.5). Oil production commenced in 1975 but was confi dently predicted soon to overtake gas production (Appendix 8.6). These years saw the development of some of the historically most important fi elds in the history of the province (Appendix 8.7). In many respects this was the most exciting time in the whole history of North Sea oil and gas.
