“…The total of active projects peaked in 1986 with polymer flooding as the most important chemical EOR method (Figure 1). However, since 1990's, oil production from chemical EOR methods has been negligible around the world except for China [93][94][95][96]. Nevertheless, chemical flooding has been shown to be sensitive to volatility of oil markets despite recent advances (e.g., low surfactant concentrations) and lower costs of chemical additives.…”

With the decline in oil discoveries during the last decades it is believed that EOR technologies will play a key role to meet the energy demand in years to come. This paper presents a comprehensive review of EOR status and opportunities to increase final recovery factors in reservoirs ranging from extra heavy oil to gas condensate. Specifically, the paper discusses EOR status and opportunities organized by reservoir lithology (sandstone and carbonates formations and turbiditic reservoirs to a lesser extent) and offshore and onshore fields. Risk and rewards of EOR methods including growing trends in recent years such as CO 2 injection, high pressure air injection (HPAI) and chemical flooding are addressed including a brief overview of CO 2 -EOR project economics.

Rich Zagros basin of hydrocarbon bearing structures in the Middle East has led to a number of oil and gas reservoirs in Iran are shared with neighboring countries. The reservoirs are integrated in geology, and in terms of property are communal. Border competition between neighboring countries has caused the shared reservoirs be in the top attention. In addition, Iran's largest oil and gas reservoirs are located in political boundaries. Therefore, a better understanding of the reservoir makes better use of them. In this article classified EOR methods base on lithology of the reservoirs and investigated the frequent EOR method (gas injection) in the carbonate reservoir that is the most reservoir lithology in Iran, gas has low viscosity and due to this property we need some complementary methods like foam flooding to overcome this disadvantage.

“…A basic overview of the petroleum geology has been done by Desheng [30]. Reservoir rocks are commonly made of sandstone or the mixture of sandstone and conglomerate rock composed of mostly clastic detritus [31]. Most of the oil fields belong to river-deltaic sedimentary systems with apparent multicyclicity, resulting in multiplayer folding traps with sharp discrepancies.…”

Abstract:Over 70% of China's domestic oil production is obtained from nine giant oilfields. Understanding the behaviour of these fields is essential to both domestic oil production and future Chinese oil imports. This study utilizes decline curves and depletion rate analysis to create some future production outlooks for the Chinese giants. Based on our study, we can only conclude that China's future domestic oil production faces a significant challenge caused by maturing and declining giant fields. Evidence also indicates that the extensive use of water flooding and enhanced oil recovery methods may be masking increasing scarcity and may result in even steeper future decline rates than the ones currently being seen. Our results suggest that a considerable drop in oil production from the Chinese giants can be expected over the next decades.
