Abstract:

2D and 3D resistivity imaging methods are simple, fast, inexpensive, and relatively accurate techniques used in geophysics exploration. In this study, 2D and 3D resistivity imaging methods are used to produce images of the subsurface structure of the University of Technology in Baghdad, Iraq. Three 2D images are utilized to create a 3D slice image and a 3D block image for three conventional arrays. Each 2D image has a length of 60m and a depth of approximately 12m, and the spacing between lines is 1.5m. Results show that the study area consists of two types of material: sandy gravel and clay. The borehole data obtained near the study area are used to confirm the results. The 2D and 3D images, as well as the three conventional arrays, are compared. Wenner array is found to be the most suitable array for 2D and 3D imaging of the study area.
