Optimization of chemical enhanced oil recovery methods for naturally fractured carbonate reservoirs
Carbonate oil reservoirs are important energy sources, accounting for over 60% of the world’s oil reserves. Recovering oil from these reservoirs is challenging, especially if they are naturally fractured. Waterflooding is inefficient because water flows through the highly permeable fractures and …

Solid-liquid-liquid Wettability and its role on Targeted Emulsified Solvent Injection (TESI)
… the third largest world reserves of crude oil, mostly in the forms of heavy oil or bitumen in the oil sands. However, 80% are too deep to be mined, requiring in-situ extraction methods. This work involved the design of a chemical enhanced oil recovery (EOR) approach, referred to as Targeted …

A Comprehensive Study and Mechanism Investigation for Alkaline-Heavy Oil Recovery Process
Alkaline flooding is an important branch of chemical enhanced oil recovery (EOR). The complexity of alkaline flooding study is mainly embodied by its chemical reaction required by alkalis to react with oil acids. Consequently, in-situ surfactants are generated for various emulsification phenomenon. …

Numerical investigation of polymer injection effects on geomechanical reservoir properties during enhanced oil recovery
Polymer injection is an enhanced oil recovery method based on the viscosity increase of the injected aqueous phase to control its mobility. The changes in mobility could affect the pore pressure distribution within the reservoir. The objective of this research work is investigating the effects of …

Mobility control of chemical EOR fluids using foam in highly fractured reservoirs
Highly fractured and vuggy oil reservoirs represent a challenge for enhanced oil recovery (EOR) methods. The fractured networks provide flow paths several orders of magnitude greater than the rock matrix. Common enhanced oil recovery methods, including gases or low viscosity liquids, are used to …

Evaluation of the performance of different polymer gel systems as an in-depth gel treatment using numerical simulation
<p>"Oil production from heterogeneous and naturally fractured reservoirs are usually hindered due to the presence of high-permeability streaks and natural fractures networks. Oil production could be more lowered if there is a crossflow from the high- to the low-permeability layers and high mobility …
