Application of hydraulic flow units’ approach for improving reservoir characterization and predicting permeability [PDF]

Journal of Petroleum Exploration and Production Technology, 2019
AbstractIt is highly essential to characterize the reservoir accurately as possible to implement enhanced oil recovery and development scenarios. Determining complex variations in pore geometry aids in identifying rock types with similar fluid flow properties.

Anabranching and maximum flow efficiency in Magela Creek, northern Australia [PDF]

, 2004
Anabranching is the prevailing river pattern found along alluvial tracts of the world's largest rivers. Hydraulic geometry and bed material discharge are compared between single channel and anabranching reaches up to 4 times bank-full discharge in Magela

Permeability prediction using hydraulic flow units and electrofacies analysis

Energy Geoscience, 2020
It is essential to characterize fluid flow in porous media to have a better understanding of petrophysical properties. Many approaches were developed to determine reservoir permeability among which the integrated analysis of hydraulic flow unit (HFU) and electrofacies (EF) is considered to be useful one.
