1. The oil extraction rate per hour is currently up to 120 crude oil. 2. That guarantees only 20 years of gas and oil production at current extraction rates . 3. For instance, plantation analysts say extraction rates at state-owned palm oil plantations are understated. 4. Iron ore maker CVRD has reserves that will last 400 years at current extraction rates . 5. Extraction rates did not change significantly above 150 rpm.6. The extraction rate is almost constant, and only flattens off towards the end of the extraction. 7. According to Ibrahim, concerted efforts are being taken to further improve productivity, particularly in oil extraction rates . 8. In milled sorghum flours, minerals such as phosphorus, iron, zinc and copper decreased with lower extraction rates . 9. There is limited information on groundwater extraction rates , or the extent of contamination at the national level. 10. Heat gains, heat extraction rate , and cooling loads values are often not equal due to thermal inertia effects.
