Lately, better oil restoration innovations have obtained a lot realization within the oil undefined. more advantageous oil restoration equipment might be divided into 3 significant different types: thermal methods which come with steam flooding, steam stimulation, and in-situ combustion; chemical procedures which come with surfactant-polymer injection, polymer flooding, and caustic flooding; and miscible displacement procedures which come with miscible hydrocarbon displacement, carbon dioxide injection of huge quantities of quite dear fluids into oil bearing reservoir formations. advertisement program of any more desirable oil restoration method depends monetary projections that express an honest go back at the funding. as a result of excessive chemical expenditures, you will need to optimize better oil restoration methods to supply the best restoration on the lowest chemical injection fee. the purpose of this booklet is to boost an optimum regulate idea for the decision of working recommendations that maximize the industrial recognition of more desirable oil restoration tactics. The selection of optimum regulate histories or working ideas is among the key components within the profitable utilization of latest superior oil restoration ideas. the knowledge inside the publication will hence be either attention-grabbing and precious to all these operating in petroleum engineering, petroleum administration and chemical engineering.

The capillary number is the ratio of viscous to interfacial forces. 4 which means that the reservoir passes the capillary criterion and is acceptable without any in-field drilling. (1-8) number screening 22 Data o n the total dissolved solids show a value of 17,500 ppm which is less than the cut off value of 80,000 ppm. We therefore find that the field passes all preliminary technical screening criteria and is a candidate for micellar/polymer flooding. We now start the computation of the economic objective index.
