“…The conventional approaches to near-surface characterization include inversion of refracted arrivals, up-hole survey techniques and more recently tomography. These approaches have been extensively discussed and applied in different basins around the world (Hampson and Russell, 1984;Zhu et al, 1992;Belfer and Landa, 1996;Lanz et al, 1998;Martí et al, 2002;Bergman et al, 2004;Yordkayhun et al, 2007;Guevara et al, 2013). The up-hole survey technique have equally been tested and applied within the Niger Delta Basin, Nigeria (Enikanselu, 2008;Igboekwe and Ohaegbuchu, 2011;Ofomola, 2011;Adeoti et al, 2013;Anomohanran, 2014).…”
