It is located in the western bank of Nasser Lake, southern Egypt, in a tectonically active area, which is dissected by many regional faults extending towards the lake. For this reason, the Nubian sandstone aquifer in this area is expected to be recharged by a large amount of seepage water from the lake. One important parameter used to quantify seepage is hydraulic conductivity. Since in this area there is no available information about hydraulic conductivity via pumping tests or laboratory examination of core samples, an attempt is made in this study to estimate hydraulic conductivity using available resistivity logs by applying the Kozeny\u2010Carman model. The clay contamination effect on porosity estimation has been removed via application of the Waxman\u2010Smits model. The hydraulic conductivity is estimated to be 9.5 \u00b1 2.5 m\/day for the Nubian sandstone aquifer in this area. The present result is in agreement with the estimated and measured hydraulic conductivity values for the same aquifer in nearby areas and could be used to estimate seepage in this zone. The application of geophysical well logging often provides a cost\u2010effective and efficient alternative to estimate aquifer parameters.<\/jats:p>","DOI":"10.3997\/1873-0604.2011009","type":"journal-article","created":{"date-parts":[[2011,5,16]],"date-time":"2011-05-16T11:24:44Z","timestamp":1305545084000},"page":"349-356","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Using resistivity logs to estimate hydraulic conductivity of a Nubian sandstone aquifer in southern Egypt"],"prefix":"10.1002","volume":"9","author":[{"given":"Mohamed A.","family":"Khalil","sequence":"first","affiliation":[{"name":"Universidade de Lisboa\u2010IDL  Campo Grande C8 Lisbon 1749\u2010016 Portugal"},{"name":"National Research Institute of Astronomy and Geophysics  Helwan Cairo Egypt"}]},{"given":"Elsa C.","family":"Ramalho","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio Nacional de Energia e Geologia Estrada da Portela  Zambujal Alfragide 2720\u2010866 Portugal"}]},{"given":"Fernando A.","family":"Monteiro Santos","sequence":"additional","affiliation":[{"name":"Universidade de Lisboa\u2010IDL  Campo Grande C8 Lisbon 1749\u2010016 Portugal"}]}],"member":"311","published-online":{"date-parts":[[2011,3]]},"reference":[{"key":"e_1_2_9_1_2_1","volume-title":"SPWLA 7th Annual Logging Symposium","author":"Alger R.P.","year":"1966"},{"key":"e_1_2_9_1_3_1","first-page":"54","article-title":"The electrical resistivity log as an aid in determining some reservoir characteristics","volume":"146","author":"Archie G.E.","year":"1942","journal-title":"Transactions of the American Institute of Mining and Metallurgical Engineers\/Petroleum Division"},{"key":"e_1_2_9_1_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00024-010-0109-x"},{"key":"e_1_2_9_1_5_1","volume-title":"Aquifer Hydraulics A Comprehensive Guide to Hydrogeological Data Analysis.","author":"Batu V.","year":"1998"},{"key":"e_1_2_9_1_6_1","volume-title":"Dynamics of Fluids in Porous Media.","author":"Bear J.","year":"1972"},{"key":"e_1_2_9_1_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2478.1996.tb00167.x"},{"key":"e_1_2_9_1_8_1","first-page":"150","article-title":"Fluid flow through granular beds","volume":"15","author":"Carman P.C.","year":"1937","journal-title":"Transactions, Institution of Chemical Engineers, London"},{"key":"e_1_2_9_1_9_1","volume-title":"Flow of Gases Through Porous Media.","author":"Carman P.C.","year":"1956"},{"key":"e_1_2_9_1_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhydrol.2008.05.023"},{"key":"e_1_2_9_1_11_1","volume-title":"Well Logging in Hydrogeology.","author":"Chappelier D.","year":"1992"},{"key":"e_1_2_9_1_12_1","volume-title":"EPM\u2010RT2003\u201003","author":"Chapuis R.P.","year":"2003"},{"key":"e_1_2_9_1_13_1","doi-asserted-by":"publisher","DOI":"10.2118\/6859-PA"},{"key":"e_1_2_9_1_14_1","volume-title":"Professional Report on Drilling of Productive Well No. (2) \u2013New Aswan City, Aswan.","author":"DASCO","year":"2003"},{"key":"e_1_2_9_1_15_1","doi-asserted-by":"publisher","DOI":"10.1190\/1.1442782"},{"key":"e_1_2_9_1_16_1","volume-title":"Geology and Groundwater Conditions of Tushka Basin Area, Egypt Utilizing Landsat Satellite Images.","author":"El Shazly E.M.","year":"1977"},{"key":"e_1_2_9_1_17_1","volume-title":"Well Logging for Earth Scientists.","author":"Ellis D.V.","year":"1987"},{"key":"e_1_2_9_1_18_1","doi-asserted-by":"publisher","DOI":"10.1029\/91JB00955"},{"key":"e_1_2_9_1_19_1","article-title":"Cyclic fluctuations of water level as a basis for determining aquifer transmissivity","author":"Farris J.G.","year":"1952","journal-title":"US Geological Survey, Ground\u2010water Hydraulics Section, Contribution No. 1"},{"key":"e_1_2_9_1_20_1","volume-title":"Report to U.A.
