Our workflow is intuitive and based on the simple concept that fine-scale single-porosity models capture fracture-matrix interaction accurately and can hence...

... Facing these great challenges, many researchers have explored the effective modeling approaches for fractured reservoirs. Currently, among these proposed approaches, two classes of models are commonly used: dual porositys models and discrete fracture model. Abstract Modelling fluid flows...

... transient Geiger fracture conductivity conductivity grid fractured reservoir Abstract Fractures often influence production behaviour in hydrocarbon reservoirs, yet the pressure transients observed in the wells may not show the conventional well-test signatures. In this case, the effect...

... Abstract Smart water injection or low-salinity water flooding is an enhanced oil recovery technique for fractured reservoirs. The mechanism of low-salinity water flooding is performed by altering the wettability of rock towards water-wetness. This study presents an evaluation of low-salinity...

... Since the dual-porosity concept was introduced by Barenblatt et al., dual-porosity/permeability models have been widely used in naturally fractured reservoirs. Primarily, the dual-porosity concept was extended to petroleum engineering for pressure transient analysis in fractured reservoirs...

... Abstract Oil recovery in fractured reservoirs by water flooding critically depends on the wetting properties of the matrix blocks between the fractures. The recovery from oil-wet reservoirs is small. In incompletely oil-wet systems, the presence of initial water may change the wettability...

... Abstract Naturally Fractured Reservoirs (NFR) contain a significant amount of remaining petroleum reserves and are now being considered for water-alternating-gas (WAG) flooding as secondary or tertiary recovery. Reservoir simulation of WAG is very challenging even in non-fractured reservoirs...

... Abstract Naturally Fractured Reservoirs (NFR) are very heterogeneous media containing highly permeable fractures in a poorly permeable rock matrix. Explicit simulations of such reservoirs are complex and computationally time consuming. Alternatively for full-field simulation, dual-medium models...

... Abstract Naturally Fractured Reservoirs (NFR) hold a significant fraction of remaining petroleum reserves. Recovery factors from NFR are usually less than in conventional reservoirs due to associated high uncertainty throughout the characterisation and modelling phases. This particularly...
