Hydraulic Flow Unit Characterization in Sandstone Reservoirs, Niger Delta, Nigeria

open access: yesEarth and Planetary Science, 2023
The key factor in a successful oil field development plan is understanding the reservoir. The effectiveness of oil extraction is determined by variations in the reservoir, specifically the distribution of porosity and permeability. To create an accurate model of the reservoir, the vertical distribution of its qualities must be determined and separated ...

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]

open access: yes, 2020
The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...

Hydrostratigraphic characterization using geoelectrostratigraphic information and hydraulic flow unit analysis for high-resolution aquifer mapping in heterogeneous systems

open access: yesGeosystems and Geoenvironment
Accurate characterization of aquifers requires comprehensive understanding of groundwater hydraulic properties. Traditional aquifer assessment techniques are usually insufficient in characterizing hydrostratigraphic variability, leading to inaccurate ...

Experimental validation of some basic assumptions used in physically based soil [PDF]

open access: yes, 2011
In spring 2009, four rill experiments were accomplished on a fallow land. Most external factors as well as discharge quantity (9 L min-1) were held constant or at least in the same range.

The impact of hydraulic flow unit & reservoir quality index on pressure profile and productivity index in multi-segments reservoirs

open access: yesPetroleum, 2017
The objective of this paper is studying the impact of the hydraulic flow unit and reservoir quality index (RQI) on pressure profile and productivity index of horizontal wells acting in finite reservoirs. Several mathematical models have been developed to
