Abstract
The sedimentary Basins of Ethiopia cover a significant portion of the country and there are five distinct sedimentary basins. Ogaden Basin is located in the southeastern part of the country and covers an area of about 350,000 sq. km. The Reservoir characterization of Adigrat sandstone of Calub Ogaden Basin Ethiopia using seismic and well-log data is the focus of this work. The data used for the study consisted of seismic lines, well logs, and published reports to achieve the aim and objectives of the work. Data from wells Calub-1, Calub-2, Calub-3, and Calub-4 were deployed. Software including Petrel, Eclipse, Interactive Petrophysics, and ArcGIS was used. A petrophysical analysis was carried out to determine porosity, permeability, water saturation, and other reservoir parameters. The methods used for analysis involved petrophysical analysis, geostatistical analysis, and reservoir modeling.
The Calub wells had relatively consistent porosity and permeability slightly lower values. Based on these results, further exploration and production activities are recommended, but additional data collection and analysis are necessary to fully characterize the reservoir properties and optimize production. This includes conducting well tests, seismic surveys, and reservoir modeling to better understand reservoir behavior and optimize production strategies.
