Water is considered ubiquitous within the shale reservoirs and mainly stored in the
hydrophilic clay minerals. The water distribution characteristics and its effect on pore …

Tight sandstone reservoirs with low porosity and permeability are always vulnerable to
damage due to drilling and fracturing fluids, which significantly impedes hydrocarbon …

Well production rates decline quickly in the tight reservoirs, and enhanced oil recovery
(EOR) is needed to increase productivity. Conventional flooding from adjacent wells is …

Experimental works and numerical simulation approaches have revealed that CO 2 huff-n-
puff could be a promising enhanced oil recovery (EOR) method of shale oil reservoirs. Latest …

This paper presents a new semi-analytical solution and the related methodology to analyze
the pressure behavior of multi-branch wells produced from natural gas hydrates. For …

In recent years, chemical flooding has become significant in oilfield development. As its
scope of application gets wider, choosing the proper chemical agent becomes an issue for …

Conventional enhanced oil recovery (EOR) approaches are inefficient in unconventional
reservoirs. This paper provides a novel approach to enhance oil recovery from …

The production of multi-stage fractured horizontal wells (MFHWs) decline fast, and water cut
quickly increase after short producing period. How to evaluate well performance and …

Tightly spaced horizontal wells are widely used in the development of unconventional
resources. The effectiveness of this strategy is largely affected by interwell fracturing …

Liquid nanofluid (LNF) has been widely used for enhanced oil recovery (EOR) in tight oil
reservoirs in recent years. However, the mechanism of oil recovery by LNF flooding is still …
