Abstract

In the complex of geological areas like fold belt with undulated topography, the data set required for modeling of the near surface is generally under sampled. The close grid up hole survey at each 1 Km is not sufficient to decipher the near surface model in such terrains. A closer sampling of up hole survey becomes uneconomical due to its drilling cost. To overcome this problem, authors adopted a new methodology of continuous shallow refraction (CSR) survey to map near surface model continuously. The efficacy of results of continuous shallow refraction survey (CSR) and its comparison with results of up hole survey at each 1 Km was compared by applying static corrections obtained by both surveys on 2D seismic data. The processed sections show that static corrections obtained using information of continuous shallow refraction survey gives better result in comparison to statics obtained through up hole survey
