Abstract
As part of the company Geoscan Service S.R.L., I was contacted to investigate the possibility of using resistivity, refraction seismic data and MASW seismic to identify the stratification up to 15m deep so that the client could choose the type of drilling rig for installing the conductor in order to drill two water injection wells. The main problem in the choice of geophysical methods was the lack of detailed geological data for calibrating the obtained results, as the presence of groundwater, the thicknesses of the deluvial layer and the bedrock. The choice of geophysical methods and the work procedure are carried out according to the international standards in force, ASTM D6429-99 “Standard guide for Selecting Surface Geophysical Methods”, ASTM D5777-00 “Standard guide for Using the Seismic Refraction Method for Subsurface Investigation, “Standard Guide for Using the Direct Current Resistivity Method for Subsurface Site Characterization”, STAS 1242/7-84 “Geophysical research of the land by seismic methods”.
