Prediction of permeability and porosity from well log data using the nonparametric regression with multivariate analysis and neural network, Hassi R’Mel Field, Algeria

Egyptian Journal of Petroleum, 2017
Most commonly, to estimate permeability, we can use values of porosity, pore size distribution, and water saturation from logging data and established correlations.

Improving Electrofacies Modeling using Multivariate Analysis Techniques: A Deepwater Turbidite Case Study

, 2011
In static and dynamic reservoir modeling, results have shown that the quality and accuracy of the models are dependent on the quality of rock and fluid property inputs e.g. facies, porosity, hydrocarbon saturation, permeability, net sand etc.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Integrated petrophysical study to validate water saturation from well logs in Bahariya Shaley Sand Reservoirs, case study from Abu Gharadig Basin, Egypt

Journal of Petroleum Exploration and Production Technology, 2020
Water saturation is a key parameter in evaluating oil and gas reservoirs and calculating OIIP and GIIP for petroleum fields. The late Cretaceous Bahariya reservoir contains variable amounts of clay minerals.

Deltas: New paradigms

The Depositional Record, Volume 10, Issue 5, Page 600-636, November 2024.
This paper discusses some new paradigms concerning the origin and significance of deltas and their deposits. It proposes a broader definition of deltas that takes into account the importance of sediment‐laden fluvial discharges in controlling deltaic sedimentation.

Field Investigation of Serpentinite With Induced Polarization and the K‐Means Clustering Technique

Geophysical Research Letters, Volume 51, Issue 18, 28 September 2024.
Abstract We performed a field induced polarization survey at Rocher du Chateau in the French Alps. This site is characterized by the presence of ophiolites with an outcrop of serpentinites. Serpentinite is characterized by high resistivity (∼0.5–10 kΩ m) and high chargeability (∼20–400 mV V−1) values.

Reservoir Quality, Lithotype Assessment, and Geochemical Source Rock Analysis: Insights from Well Logs and Pyrolysis Data, Karama Field, North‐Western Desert, Egypt

Geofluids, Volume 2024, Issue 1, 2024.
Reservoir characteristics and source rock geochemistry are essential for petroleum system investigation as they reveal reservoir quality and hydrocarbon generation capability, respectively. The primary Karama oil field reservoir of Abu El Gharadig Basin is the limestone‐sand‐shale Abu Roash G (AR/G) Member.

Seismic expression of miocene carbonate platform and reservoir characterization through geophysical approach: application in central Luconia, offshore Malaysia

Journal of Petroleum Exploration and Production Technology, 2021
A substantial proportion of proven oil and gas reserves of the world is contained in the carbonate reservoir. It is estimated that about 60% of the world’s oil and 40% of gas reserves are confined in carbonate reservoirs.

Geological modeling of diagenetic logs of the Sarvak reservoir in Dezful Embayment, southwestern Iran: implications for geostatistical simulation and reservoir quality assessment

Journal of Petroleum Exploration and Production Technology, 2023
Reservoir quality in carbonate reservoirs is significantly influenced by diagenetic processes. Although diagenesis is studied as a common reservoir quality damaging/enhancing process in many previous studies, literature is limited about the spatial ...
