THE USE OF GEOPHYSICS APPLICATIONS IN GROUNDWATER EVALUATION

Abstract

It is important for any civil engineer to take the advantage to work on studies that can add to him/her more dimensions to his/her experience specially the environmental studies because it is a multidisciplinary science.

The objectives of the study fulfilled their aims and gave a good knowledge as a civil engineer for some important methods related to the environmental engineer`s duty.

The study was targeting using geophysical field data in evaluating the groundwater and the aquifer of Wadi El Rayan study area from an environmental perspective and doing some petro-physical studies using some important methods and theories that helped the study to accomplish this assessment.

After collecting the all available geophysical field data for Wadi El Rayan study area during the life time of the study(final processed reflected seismic data and well logs), a verification step started directly to check the validity of these data before doing any further step, the verification step required to convert the well log information from depth to time using the check shot that acquired in the field to be able to load the well logs on the stacked seismic lines in time domain to check if the formation tops of the of the well was matched with the processed seismic data or not, this step was done correctly and the results of the verification step was excellent.

The next step was calculating the total porosity and the water saturation of WR 2X well using the given information while drilling the well to know the probability of the existed groundwater in Apollonia formation`s
