  35. 35. Final Remarks During at least the next 20 years, oil and gas production from mature fields will supply at least half of the World’s demand for energy. Old paradigms for oil and gas production will be eclipsed by new practices, new drivers and new technologies geared towards increased recovery from mature fields. The continued high oil price scenario, coupled with new tools, technologies and processes will make 70% recovery targets for low complexity reservoirs a reality .
