An Overview of Enhanced Oil Recovery Methods in Fractured Carbonated Reservoirs-Juniper Publishers
Juniper Publishers Abstract In some cases that the fluid (oil) enter in the bottom of the well and the fluid pressure in the bottom of the well is not capable to bring them to wellhead, other techniques such as gas lift (gas is injected from the surface into the well and this gas with well oil creates mixed miscibility that the density is less than primary oil density and can be transmitted oil to wellhead with that bottom pressure) or down-hole pumps (the oil is pumped from the bottom to wellhead by this device) is used. But, this technique is not mentioned as one of EOR methods. Introduction When a reservoir was being drilled, firstly it was produced by the natural mechanisms. Natural mechanisms provided the substantial energy to push the fluid mainly included oil and gas to the surface [1,2]. Oil expansion is a very important part among those mechanisms if without availability of other artificial introduced energy. The rock a...
