Screening Reservoir Candidates for Enhanced Oil Recovery (EOR) in Angolan Offshore Projects

Angolan Mineral, Oil & Gas Journal, 2020
The neuro-fuzzy (NF) approach presented in this work is based on five (5) layered feedforward backpropagation algorithm applied for technical screening of enhanced oil recovery (EOR) methods. Associated reservoir rock-fluid oilfield data from successful EOR projects were used as input and predicted output in the training and validation processes ...

A Mathematical Model for Two‐Phase Flow in Confined Environments: Numerical Solution and Validation

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 306-320, March 2026.
We present a numerical framework based on the Cahn‐Hilliard‐Navier‐Stokes (CHNS) model to simulate biphasic flow in confined environments. After deriving the mathematical model, we develop the weak form of the system of PDEs using a pedagogical approach to enable its implementation in FEniCS.

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed
