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 …

Determining gas and oil minimum miscibility pressure (MMP) plays a vital role in the
enhanced oil recovery. Injecting gases above the MMP into oil reservoirs leads to a …

The lack of fundamental understanding of the chemistry governing elemental mercury (Hg0)
immobilization over metal chalcogenides (MChals) is the key challenge impeding the …

Abstract The Tahe Ordovician carbonate reservoir is special and unique, with its fracture and
cavity serving as both pathway and crude oil storage space. Additionally, its extra-heavy …

Unconventional shale or tight oil/gas reservoirs that have micro-/nano-sized dual-scale
matrix pore throats with micro-fractures may result in different fluid flow mechanisms …

Jetting is preferentially adopted for surface conductor installation in deep-water oil and gas
facilities. Surface conductor bearing capacity decreases due to soil disturbance, which is the …

In this study, numerical simulation studies have been conducted to enhance oil production in
X1 heavy oil reservoir using nitrogen-assisted steam injection processes. Five types of …

The majority of lost circulation events during drilling include drilling fluid losses through
natural or drilling-induced fractures, but this problem can be prevented by understanding …

Borehole instability problem is always common when intersecting the brittle shale formations
using either water-based mud or oil-based mud. An extensive wellbore stability drilling fluid …
