In the exploitation of tight oil and gas reservoirs, multi-stage hydraulic fracturing technology
is mainly used and a complex system of fractures and matrix is formed after fracturing. In the …

A wide range of enhanced oil recovery (EOR) methods has been proposed to accelerate the
recovery of remaining oil in subsurface reservoirs. One important class of methods is water …

A solvent-based thermal recovery process has the advantages of low capital expenditure,
less energy consumption, and less greenhouse gas emission. Dimethyl ether (DME), as a …

In this paper, the interfacial properties of a rock/heavy-oil/steam system were measured to
observe the degree of wettability alteration when adding new generation chemicals to steam …

Conventional enhanced oil recovery (EOR) methods can cause environmental and
ecological problems with high costs. Several studies demonstrate that recent research on …

Oil-wet reservoirs suffer from an incomplete oil recovery. It is possible to use nanoparticles
(NPs) to alter the reservoir rock wettability to a more water wet condition, and thus increase …

The efficiency of the dimethyl ether (DME) enhanced oil recovery (EOR) technique in a
fractured chalk reservoir core plug was investigated. The coreflood experiment showed that …

North Sea tight chalk oil reservoirs are well-known for their submicron pore throat sizes and
heterogeneous porosity pattern that includes fractures and microfractures. The host rock of …

This paper presents a comparative study of two wettability modifiers with different
characteristics for enhancing water imbibition from a fracture into the surrounding matrix …

Dimethyl ether (DME) is a compound first introduced by Shell as a chemical solvent for
enhanced oil recovery (EOR). This study aims to investigate the efficiency of EOR using the …
