Enhancing Wettability in Carbonate Reservoirs for Efficient Oil Recovery: Unraveling the Molecular Mechanisms through Simulation-Based Investigations [PDF]

Iranian Journal of Chemistry & Chemical Engineering
Retaining entrapped oil in carbonate reservoirs is a critical challenge in the oil industry. However, the mechanisms governing wettability alteration for Enhanced Oil Recovery (EOR) on carbonate surfaces remain poorly understood.

A Review of Wettability Alteration by Spontaneous Imbibition Using Low-Salinity Water in Naturally Fractured Reservoirs

Energies, 2023
Analysis of fluid flow in naturally fractured reservoirs (NFRs), as a highly heterogeneous and complex system, requires a detailed study of the fracture-matrix interactions.

Role of divalent ions, temperature, and crude oil during water injection into dolomitic carbonate oil reservoirs

Oil & Gas Science and Technology, 2019
Although wettability alteration has been shown to be the main control mechanism of Low Salinity and Smart Water (LS-SmW) injection, our understanding of the phenomena resulting in wettability changes still remains incomplete.

Applying low-salinity water to alter wettability in carbonate oil reservoirs: an experimental study

Journal of Petroleum Exploration and Production Technology, 2020
Seawater has been widely used as an injection fluid for maintaining pressure in sandstone and carbonate reservoirs. In the literature related to EOR research, it was noted that diluted seawater (low-salinity water) can highly improve recovery due to the ...

Oil recovery and wettability alteration in carbonates due to carbonate water injection

Journal of Petroleum Exploration and Production Technology, 2017
Enhanced oil recovery in carbonates due to wettability alteration has received much attention recently. In contrast to sandstones reservoirs, carbonates are neutral-wet or preferentially oil-wet.

Green Lignosulphonate as co-surfactant for wettability alteration

Petroleum Research, 2020
Surfactant flooding is one of the common tertiary method to recover remaining oil in the reservoir, by reducing the interfacial tension (IFT) between two immiscible fluids nevertheless, current surfactant forms emulsion and difficult to achieve ultra-low

Enhanced Oil Recovery by Cyclic Injection of Wettability Alteration Agent for Tight Reservoirs

Geofluids, 2021
Low primary recovery factor and rapid production decline necessitates the proposal of enhanced oil recovery methods to mobilize the remaining oil resource of tight reservoirs, especially for oil-wet ones, and wettability alteration by injecting a ...
