Due to the presence of vertically sloping bedrock, cavities, and sinkholes, geotechnical engineers face significant challenges when designing and constructing foundations in karstic formations such as limestone. The territory under investigation is located close to the Giza limestone plateau, the northern side of which has experienced severe stability issues. The ground-penetrating radar (GPR) method was used to identify the presence and extent of exposed caves and caverns in the studied region. The research area’s geological and geomorphological background is explored, including the creation of primary and secondary caves, as well as solution caves generated by the breakdown of soluble rocks like limestone. Data collecting, processing, and interpretation procedures used in the GPR survey are described. GPR survey findings revealed the existence of a severe cave and many minor sinkholes in the studied region. GPR has shown to be a useful and efficient tool for determining geometric karst features in the subsurface, helping to a better evaluation of the dangers associated with this geological environment.","PeriodicalId":100964,"journal":{"name":"NRIAG Journal of Astronomy and Geophysics","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It employs subsurface lithological data from 48 drilled wells dispersed over the area and gravity data. The study was based on applying the gravity stripping technique. The gravities of five well-defined depositional cycles (cycle I, II, III, IV, V) of diverse ages were calculated depending on each cycle's density and thickness obtained from the available well data. Maps were prepared for each cycle and the surface of basement rocks from which the characteristic structures were traced. New linear empirical relationships were concluded with a correlation coefficient of 0.9 from linear relationships. Accordingly, reservoir characterizations were calculated for the reservoir at the sites in which neither seismic nor well logging data are available. Contour maps were prepared for each parameter to reveal the areal distribution of these parameters in all study areas. Maps revealed that, at Abu Gharadig basin, the predicted density varies from 2.3 g/cm3 to 2.7 g/cm3, effective porosity from 13% to 30%, and hydrocarbon saturation from 50% to 90%. The main deep subsurface structure trends are the E-W, the WNW-ESE, the ENE-WSW, the NE-SW, the NW-SE, and the N-S trends.","PeriodicalId":100964,"journal":{"name":"NRIAG Journal of Astronomy and Geophysics","volume":"10 1","pages":"224 - 236"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82220832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
