Résumé: Seismic inversion is a method of processing seismic data to predict different properties of rocks such as density, compressibility, velocity, water saturation, porosity, permeability, and layer thickness. This is how it seems important to us to use seismic inversion to characterize the nature of reservoir rocks. This work uses the different types of seismic inversion that are related to AVO analysis to perform lithological analysis of hydrocarbon reservoirs using 3D seismic data from Penobscot located in offshore Nova Scotia (Canada). These are elastic inversion, acoustic inversion, and inversion by attributes which constitute the methods used. The results allow good discrimination of different layers of hydrocarbon reservoirs using a combination of attributes. Thus, the cross-plotting of the density and the Poisson ratio made it possible to highlight four facies.2024-01-01T00:00:00ZPetrophysical Parameters Curves’ Calculation for Non-conventional Reservoirs’ Modeling and CharacterizationDoghmane, Mohamed ZinelabidineOuabed, NoureddineEladj, Saidhttp://dlibrary.univ-boumerdes.dz:8080/handle/123456789/137252024-03-25T08:13:50Z2024-01-01T00:00:00ZTitre: Petrophysical Parameters Curves’ Calculation for Non-conventional Reservoirs’ Modeling and Characterization
Auteur(s): Doghmane, Mohamed Zinelabidine; Ouabed, Noureddine; Eladj, Said
Résumé: The quantitative petroleum reservoir analyses’ topic is one of the biggest challenges facing geo-modelers. The difficulty lies in the fact that the constructed model depends on many empirical Archie’s law parameters such as tortuosity factor (a), cementation exponent (m), and saturation exponent (n). The most used methodology of choosing the appropriate set values of (a, m, n) is the trial/error technique. The parameters values’ sets are calculated empirically based on core data taken from different wells. The main drawback of this method is that these petrophysical parameters are not constant all over the reservoir section and are very variant in non-conventional reservoirs. The objective of this study is to provide curves of the petrophysical parameters (a, m, n) from petrophysical logs based on new equations. The new equations are based on relating tortuosity as a function of the sonic log and other basic logging curves (Gamma Ray, Neutron-density). Then, the calculated curves are used in constructing a more accurate non-conventional reservoir model. The obtained results have been compared to the conventional interpretation where a, m, and n are taken constants for all reservoir sections. Moreover, the obtained results are validated through core data and MDT tests in Algerian Southern non-conventional reservoirs.2024-01-01T00:00:00ZTri-Band endfire antenna array with wide Angles of Beam-Scanning capability for 5G mmWave mobile communicationZidour, AliAyad, MouloudAlibakhshikenari, MohammadBasherlou, Haleh JahanbakhshParchin, Naser OjaroudiSee, Chan Hwanghttp://dlibrary.univ-boumerdes.dz:8080/handle/123456789/137002024-03-14T08:42:41Z2023-01-01T00:00:00ZTitre: Tri-Band endfire antenna array with wide Angles of Beam-Scanning capability for 5G mmWave mobile communication

Résumé: In this paper, a novel multiband phased array antenna with endfire radiation pattern is designed at millimeter-wave (mmWave) frequency bands for 5G mobile applications. The proposed antenna element is a compact quasi-Yagi with a modified dipole driver to generate multiband operation, arranged on low-loss RO4003C materiel. The antenna array achieves excellent performance and covers wide frequency ranges of (24.15-29.8 GHz), (36.2-50 GHz) to support 5G NR bands; 26, 28, 39 and the new allocated 48 GHz. The array can exhibit a maximum realized gain from 8.4 dBi to 11.8 dBi. Meanwhile, wide beam-scanning angles from - 68° to 65° at 28 GHz, from 40° to 41° at 39 GHz, and from - 33° to 35° at 48 GHz are realized.2023-01-01T00:00:00ZSimulation and Optimization of a Microgrid Energy Management SystemDassa, KhaledRecioui, AbdelmadjidDekhandji, Fatma Zohrahttp://dlibrary.univ-boumerdes.dz:8080/handle/123456789/136922024-03-11T07:57:40Z2023-01-01T00:00:00ZTitre: Simulation and Optimization of a Microgrid Energy Management System
Auteur(s): Dassa, Khaled; Recioui, Abdelmadjid; Dekhandji, Fatma Zohra
Résumé: This paper deals with the deployment and integration of renewable energies and storage systems. An Energy management system is necessary to achieve this objective. Two energy management techniques are considered in this work. They are termed: 'heuristic' and 'optimization' methods. Both methods aim to reduce the overall reliance on the conventional energy source from the main grid by maximizing the output of the two other sources (solar energy and storage system) and thus, reducing the overall cost. This study contrasts the two methods in terms of both grid usage and cost. Simulations considering cloudy and clear sky conditions while ensuring the user's satisfaction are carried out.2023-01-01T00:00:00Z
