Basement Depth Estimation Using Euler Deconvolution and Source Parameter Imaging; a Case Study of Northeastern Part of Sokoto Basin, Nigeria

Abstract

Euler deconvolution and Source Parameter Imaging (SPI) geophysical interpretation techniques using Oasis Montaj version 6.4 was applied to estimate basement depth of northeastern part of Sokoto basin, northwestern Nigeria. The study area lies between longitudes of 505"E to 605"E and latitude 1205"N to 1305"N. The results of the studies indicate an increase in sedimentation northwards, with several depressions on the basement rock. The Euler deconvolution results shows the maximum depth in the study area to be 2.39 km, while Source parameter imaging indicates 1.79 km to be the highest depth. The areas where higher sedimentary thickness are observed such as sheet 11 (Rabah) and sheet 12 (Isah), are the most prospect sites where threshold temperatures could be attained.
