The optimal configurations of the injection and producer wells are chosen using the differential evolution approach and particle swarm optimization techniques. The technique was programmed for the numerical...

... and ΔP=pressure drop in core flood experiment. Brine flooding The core samples are first saturated or injected with brine. This is to create a replica of the situation that occurs in the reservoir and to fill up pore spaces. This technique involved the following steps: Brine was made by dissolving...

... saturation. However, polymer flooding was designed to improve sweep efficiency by improving the mobility ratio. In Nigeria, EOR materials and technologies are virtually imported, making them limited and expensive to use. This study is aimed at designing and constructing an efficient locally made core...

..., Enhanced Oil recovery techniques such as thermal flooding are typically employed to propel additional oil from the reservoir toward the production wells. Nigeria's unconventional oil reserves can be deduced to hold approximately 42 billion barrels of untapped crude trapped in unconventional reservoirs...

... Besides the heavy oil deposits, at the end of primary recovery, there is still 85-95% of the original oil resource left in place, furthermore, literatures show that 40% to 55% of oil reserves are usually left in-situ after primary and secondary recovery processes such as water flooding...

...) methods provide an avenue to Petroleum engineers to unravel this challenge. In lieu of this, we investigated the feasibility of improving recovery with polymer flooding technique in the Niger Delta region of the Sub-Sahara Africa. A sequence of brine saturation, oil saturation, water flooding and polymer...

... Abstract In this work, we present extensive study of Alkaline-Surfactant-Polymer (ASP) flooding in reduction of residual oil saturation in both core plugs and heterogeneous beads-packs. During the ASP flooding of the core plugs, the effectiveness of the ASP flooding EOR technique on a typical...
