Due to the continuous depletion of crude oils in the reserves, and continuous rise in energy
demand, there is currently a widespread interest in various methods of chemical enhanced …

Primary oil recovery remains less than 10% in tight oil reservoirs, even after expensive
multistage horizontal well hydraulic fracturing stimulation. Substantial experiments and pilot …

Primary oil recovery from fractured unconventional formations, such as shale or tight sands,
is typically less than 10%. The development of an economically viable enhanced oil …

In recent times, particularly in the 21st century, there has been an alarming increase in the
demand for global energy, along with continuous depletion in conventional oil reservoirs …

Unconventional oil reservoirs have become an increasingly essential resource for energy in
recent years. Despite the massive oil reserves in these reservoirs, as well as the current …

Tight oil reservoirs are contributing a major role to fulfill the overall crude oil needs,
especially in the US. However, the dilemma is their ultra-tight permeability and an …

This paper presents a new perspective on modeling of CO 2 and miscible gas injection into
shale oil plays for potential enhanced oil recovery (EOR) and CO 2 storage. Our major …

Diffusion is the key mechanism of enhanced oil recovery (EOR) by CO 2 injection in
unconventional oil reservoirs. The accurate measurement of the diffusion coefficient in …

Experimental observations and field applications have revealed that surfactants have
significant potential to enhance oil recovery in unconventional liquid reservoirs (ULR). This …

This work provides a comprehensive workflow with practical guidelines for integrating
fracture-geometry, rock stress-sensitivity, and gas molecular diffusion to evaluate the …
