Answer 1

Solution : What is the motivation behind progress in For ? Enhanced Oil Recman, CEOR) is today's essential technique to extract the oil from the nack 3irata. It is not like fracturing It helps to fulfill the demand of oil. There are several reason behind progress in Eor. Methods of EOR :- 1. Chemical EOR 2. ltydrodynamie EOR 3. Gas EOR ete. 2 Motivation behind progress in for 1. High oil price during 1972 - 1980 : Suddenly decreasing the supply of oit, enhance the oil price. in high rate for that reason, some researcher tried to explore the Concept of EOR. It was initiated to supply the demand of oil in future for a long time.

FOR helps to extend the life of oil field. : Well use of oil fields is very much necessary for extraction of oil for a long time. Previren technique were not farounable for sustaing long time of oil fields. But EOR technique is less harmful for the ruch Strenta, and also increase the oil reproduction, oil in Supply more and more future : - EOR helps to discover new oil fields and reserve the oil for feature. If we do not use a better technique, we can not produce huge roume of oil for future. W FOR helps to increase recovery factor. - Recovery factor (RF) is increased well by the method of Foo we can use or extract more pure Oil by this technique. It helps in natural flow of oil to extract from the underground.

5 with the new EOR will be increased tenehnologies :- Researcher are suggesting that betten tenchnology is always helpful to enhance the rate of EOR. It is costly but helpful for fulfill the demande 6 The underlying rock strata is left in place - C EOR is not like fructuring It helps rock strata is left in place. It use modern technique to extract the oil which ane faraonable for the underlying rock stratea. Conclusion] → So, these are the motivation to progress EOR. Today, it is the most essential technique for reserring Crude oil. FOR will be grown in fe there more with the new modern technologies.
