The EOR process mainly involves the application of surfactants to mobilize the oil left in warming pollution: a process known as carbon dioxide enhanced oil recovery.

25 Mar 2017 Being a student of this discipline, you have got to learn those processes well like secondary recovery methods. To do that, you need to study a www.npc.org the oil recovery factor. When oil is displaced by water, the oil/water mobility ratio is so high that the injected water fingers through the reservoirs. By injecting polymer solution into reservoirs, the oil/water mobility ratio can be much reduced, and the displacement front advances evenly to sweep a larger volume. • Step 1 in the refining process is to remove these contaminants so as to reduce corrosion, plugging, and fouling of equipment and to prevent poisoning catalysts in processing units. • Step 2 most typical methods of crude-oil desalting are chemical and electrostatic separation , and both use hot water as the extraction agent.
Oil recovery refers to the additional recovery that result from the conventional methods of water-injection and immiscible gas injection. Usually, the selected secondary recovery process follows the primary recovery but it can also be conducted concurrently with the primary recovery. Oil Recovery is a process of extracting crude oil from an oil field. There are three different phases of Oil Recovery, i.e., primary, secondary and tertiary. Many oil wells reach their maximum production range and it becomes difficult to extract the remaining natural resources from the oil fields. Enhanced oil recovery (abbreviated EOR ), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. primary oil recovery factors range from 20 % and 40%, with an aver age around 34%,while the remainder of hydrocabon is left behind in the reservoir (Satter et al., 2008). Once the natural reservoir energy has been depleted and the well oil production rates = average porosity of formation, dimensionless. Soi = initial oil saturation in pore space, fraction. Boi = oil formation volume factor at initial reservoir pressure, reservoir barrel/stock tank barrel. Recovery factors are a function of the fluid displacement and areal and vertical sweep efficiencies. Enhanced Oil Recovery (EOR) • Process recovers oil not produced by primary or secondary recovery • Improves sweep efficiency in the reservoir by the injection of materials not normally present • Can reduce remaining oil saturation • Produce oil trapped by capillary forces (residual oil) • Produce oil in areas not flooded by earlier injections (bypassed)
