... is subject to an initial CO 2 injection concentration at the inlet and a boundary condition with free flow at the outlet ( Lake et al., 2014 ; Ghanbarian et al., 2023 ). The proposed conceptual model relies on several assumptions to simplify multiphase-component transport in carbonate reservoirs...

... and industry have paid more attention to low salinity water (LSW) enhanced oil recovery (EOR) in carbonate reservoirs with a variety of mechanisms. Instead of widely-discussed mechanism of rock-fluid interaction (i.e., wettability alteration), recent research has focused on fluid-fluid interaction (FFI) which...

... Abstract This work presents the first worldwide application of a new-generation, single-phase, low-viscosity retarded acid developed to effectively stimulate wells in High-Pressure, High-Temperature deep carbonate reservoirs. While single-phase retarded acid has shown success since...

The economic value of this result can be better appreciated if we consider that it is associated only to the re-distribution of the injection rate, without any additional capex. carbonate reservoir complex...

... Abstract Polymer injection has been widely established for mobility and conformance control during enhance oil recovery (EOR). However, its role in resolving the water-channeling problem in carbonate reservoirs becomes challenging due to the existence of heterogeneous and complex fracture...
