Oil recovery co2 foam

The residual oil recovery increased from 67.7% to 80.1% as the operation pressure increased from 1200 psi to 2500 psi. This can be attributed to the increase in CO2 foam stability with the increasing in pressure [15], [16]. As the pressure increases, the stability of nanoparticle-stabilized CO 2 foam increases.

Enhanced oil recovery (EOR) via carbon dioxide (CO2) flooding has received a considerable amount of attention as an economically feasible method for carbon  

enhanced oil recovery. The low viscosity of the injected CO 2 at reservoir conditions leads the poor macroscopic sweep, especially in heterogeneous reservoirs. Foam injection increase the displacement efficiency compared to gas injection in heterogeneous and fractured reservoir (Rossen, 1996). Foam generates when gas contacts Our enhanced oil recovery (EOR) integrated chemical services are proven solutions for some of the most challenging production conditions. Regardless of the E

EOR and CO2 storage were evaluated at reservoir conditions, showing higher CO2 storage and increased oil recovery during foam injections in presence of oil. Results indicated a carbon neutral oil production from CO2-foam injection, where 96% of the carbon atoms in the produced oil was stored (as CO2) in an ax-ante storage process. Foam has been applied in enhanced oil recovery (EOR) for more than sixty years. The surfactant-stabilized N 2 /CO 2 foams are two of the most widely used foams in foam EOR processes, and numerous oil reservoirs could potentially benefit from them. This paper comprehensively reviews the development of these foams over the past decade. CO 2 foam for enhanced oil‐recovery applications has been traditionally used in order to address mobility‐control problems that occur during CO 2 flooding. However, the supercritical CO 2 foam generated by surfactant has a few shortcomings, such as loss of surfactant to the formation due to adsorption and lack of a stable front in the presence of crude oil.

Diffused oil bank is formed ahead of the foam front, which results in additional oil recovery, compared to pure gas injection. CO2 hardly foams in the oil-bearing  CO2-foam yields improved sweep efficiency in enhanced oil recovery (EOR) applications over that of polymers to avoid potential polymer-induced formation damage. In addition to carbon sequestration in underground formations, CO2 foam has low water content, which also reduces formation damage in water-sensitive formations and allows for fast cleanup. Carbon dioxide (CO2) foam flooding is a promising carbon capture, utilization, and storage technology that is often used for enhanced oil recovery (EOR). However, the instability of foam and low displacement efficiency restrict its efficient utilization.
