The research on method of interlayer modeling based on seismic inversion and petrophysical facies

open access: yesPetroleum, 2016
Currently, the three-dimensional distribution of interlayer is realized by stochastic modeling. Traditionally, the three-dimensional geological modeling controlled by sedimentary facies models is built on the basis of logging interpretation parameters ...

Linking Between Sedimentary Facies and Petrophysical Rock Type: A Case Study

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Rock typing is a technique of grouping rocks that have similar properties, which properties can be in the form of sedimentary, petrophysical, and reservoir parameters. Classification based on sedimentary parameters is called sedimentary rock type (SRT), while grouping based on petrophysical parameters is called petrophysical ...

Sedimentary facies controls on reservoir quality of the Abu Madi Formation, offshore Nile Delta Basin, Egypt

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
The present study investigates the sedimentological analysis and petrophysical properties of the Messinian Abu Madi reservoir (AMR), offshore Nile Delta Basin in order to determine how facies heterogeneities control reservoir quality.
