Magnetic and Seismic Studies For Delineation of The Shape and Parameters of El-hamra Water Reservoir Burred Structure, Western Desert, Egypt
Abstract
An intensive study have been performed to El-Hamra area in order to illustrate the role of the magnetic and seismic interpretation in the detection of subsurface tectonics that controlling the subsurface water reservoir and the surface salt lakes in the studied area. The execution of this investigation was initiated by the construction of a total magnetic intensity anomaly map for the area. Two proton magnetometers were used, for measuring the total intensity of the different points grid like configuration. The total intensity magnetic map was transformed to the reduced to the pole magnetic map (RTP). This step was followed by application of linear wavelength, Walter and Mark method (1993 after modifications. two-dimensional modeling and seismic interpretations. A comparative analysis was carried for the different filtered magnetic maps. It was found that the main tectonic trends taking the directions NW - SE and NE - SW The result of application of Walter and Mark method (1993) to the RTP magnetic anomaly show that there are three faults are bounding El - Hamra area from east, west and south directions. The two dimensional modeling technique was applied to these which indicates that these fault lines causing a graben and crossing El - Hamra area. The results of seismic interpretation method indicate that there are two faults extended from the basement to the sedimentary rocks. One of these fault line is the wat er reservoir at El -Hamra area causing El-Hamra water spring. The depth to this fault reaches about 85 feet from the ground surface. These results confirm the results obtained from the other methods used for magnetic interpretations.
