The promise and problems of enhanced oil recovery methods
CO 2 injection, already the most common EOR method, holds even greater promise if it can be applied to mature oil fields across the country. The three research focus areas of Enhanced Oil Recovery are CO 2 EOR, environmental, and other EOR and oil resources. CO 2 EOR Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. secondary recovery (conventional recovery) targets mobile oil in the reservoir and tertiary recovery or EOR targets immobile oil (that oil which cannot be produced due to capillary and viscous forces). Primary, secondary and tertiary (EOR) recovery methods follow a natural progression of oil production from the start These new technical developments fall under the broad heading of enhanced oil recovery (EOR). Enhanced oil recovery is a collection of general methods, each with its own unique capability to extract the most oil from a particular reservoir. Each has been investigated rather thoroughly both from a theoretical and laboratory perspective, as well Enhanced oil recovery (EOR) is the technique or process where the physicochemical (physical and chemical) properties of the rock are changed to enhance the recovery of hydrocarbon. The properties of the reservoir-fluid system which are affected by EOR process are chemical, biochemical, density, miscibility, interfacial tension (IFT)/surface
There are several methods for enhanced oil recovery that used in the oil fields. these two problems in this article and find the best method for solving them.
As a result, the oil expands, the viscosity drops and the permeability increases. To ensure success, the process has to be cyclical. This is the principal enhanced oil recovery program in use today. In situ combustion of oil on site or fire flood, works best when the oil saturation and porosity are high. Part II gives the description of the most developed and effective oil recovery methods. The presented classes of methods include hydro-dynamic, thermal, physic-chemical, gas and microbiological ones.

There is no known method or collection of methods that can recover all of the petroleum from an underground reservoir. Even when sev eral different methods are applied sequentially over a period of decades, on average, they leave about two-thirds of the oil trapped in the reservoir (1). Enhanced oil recovery (EOR) is a collective term for various ACS Journals ; ACS eBooks ; C&EN Global Enterprise; A; Accounts of Chemical Research; ACS Applied Bio Materials - New in 2018 Of the enhanced oil recovery methods currently being considered for application to many of the nation’s older oil fields, carbon dioxide flooding may offer the largest potential for additional oil recovery. The physical mechanisms by which CO 2 contacts and mobilizes crude oil are reviewed.

The physical mechanisms by which CO2 contacts and mobilizes crude oil are reviewed. Enhanced oil recovery (EOR) is the process of recovering oil not already extracted from an oil reservoir through primary or secondary recovery techniques. Those techniques rely on natural or enhanced pressures to force oil out of the ground. As a result, the oil expands, the viscosity drops and the permeability increases. To ensure success, the process has to be cyclical. This is the principal enhanced oil recovery program in use today.
