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

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 …

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 …

Although well logs and core data show that there is significant oil content in Bakken shales,
the oil transport behavior in these source rocks is still not well understood. This lack of …

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 …

Considering the worldwide development of tight and ultra-tight oil reservoirs, the increasing
demand for fossil energy and long-term environmental concerns regarding large CO 2 …

In this study, Huff-n-Puff (HnP) experiments were conducted to investigate the potential for
producing hydrocarbons from the shale core samples using CO 2 HnP and N 2 HnP …

Enhanced oil recovery (EOR) from shale oil formations is recognized as the next frontier in
the exploitation of unconventional resources. Current approaches for performing EOR …

CO 2 injection in tight oil reservoirs is a proved method for enhanced oil recovery. The mass
transfer between CO 2 and oil makes the reservoir fluid phase behaviors very complex, and …

The strong interactions between kerogen and CO 2 give an opportunity to enhance shale oil
recovery (EOR) by CO 2 injection, and also reduce greenhouse gas emissions through CO 2 …
