Application of Improved Artificial Neural Network Algorithm in Hydrocarbons’ Reservoir Evaluation: Artificial Intelligence in Renewable Energetic Systems
(2019) Doghmane, Mohamed Zinelabidine; Belahcene, Brahim; Kidouche, M.
The aim of this work is to develop an artificial neural network software tool in Matlab which allows the well logging interpreter to evaluate hydrocarbons reservoirs by classification of its existing facies into six types (clay, anhydrite, dolomite, limestone, sandstone and salt), the advantage of such classification is that it is automatic and gives more precision in comparison to manual recognition using industrial software. The developed algorithm is applied to eleven wells data of the Algerian Sahara where necessary curves (Gama Ray, density curve Rhob, Neutron porosity curve Nphi, Sonic curve dt, photoelectric factor curve PE) for realization of this technique are available. A graphical user interface is developed in order to simplify the use of the algorithm for interpreters
Geological Description and Modeling of Djebel Kerdada in Saharan Atlas–Bou Saada, Algeria
(Springer Nature, 2023) Belahcene, Brahim; Doghmane, Mohamed Zinelabidine; Eladj, Said
This paper presents stratigraphic and structural descriptions of Djebel Kerdada in the studied areas of Bou Saada in Algeria. The choice of Djebel Kerdada is due to its geological complexity that can provide more detailed information about the regional geology of the area located at the northern limit of the African plate. This region belongs, geologically, to the Saharan Atlas, which is limited by flexures caused by slow dislocations, transgression, alternations, and regressions. The marginal basin in western Mediterranean Sea was generated by an N-NW subduction of the African and Adriatic plates under the European plate. The geological structures created by the subduction are near the city of Bou Saada, which is located 234 km South-East of Algiers. Based on the results of field investigation internship, it has been confirmed that, due to the compressive tectonic phenomenon caused by the sliding of the African plate under the Euro-Asian plate, many geological structures have a N-E/ S-W direction. Thus, this field study allowed us to limit the different litho-stratigraphic series that appeared in the form of outcrops, fossils, measurement of dips, and all structural faults. Moreover, a static modeling of the geological structure, namely Djebel Kerdada, was established based on the isopath maps of the region and data obtained from the internship. In addition to the limits of the litho-stratigraphic series, the results demonstrated the paths of the hydro-geodynamic forces toward the river of Bou Saada.

Study on Corrosion Behavior of HLE steel solicited in (CO 2 ) % Selective Physicochemical medium
(2016) Belahcene, Brahim; Benmoussat, Abderrahim; Mansri, Ali; Doghmane, Mohamed Zinelabidine
n petroleum industry, conventional and unconventional reservoirs have to be controlled in order to decrease the effect of hazardous components on Oil and Gas facilities, as well as equipment completion, production tubing, transport pipeline, and storage tank. Herein, the study of real state of this effect using empirical method to determine sensible parameters that have huge influence on materials degradation. Therefore, the corrosion rate is estimated by application of a theoretical calculation based on physicochemical parameters and meta-field parameters, such as medium acidity, CO 2 partial pressure, thermodynamics parameters (P, T), and mechanical proprieties of studied materials. Moreover, scenarios application permitted us to assess corrosion risk
