Abstract

In 2015 the SPWD-wireline prototype incorporating a phased array vibration source and two three component receivers has been tested at the “Piana di Toppo” test site in Italy. The test aims to demonstrate its applicability, the estimation of the exploration range and to calibrate the sonde for its application in a sedimentary rock environment. To ensure a safe operation during the well test a temperature monitoring system, tool azimuth measuring system and a trigger-system for combined downhole and surface measurements were integrated. Besides single frequency transmission tests between 120 Hz and 1920 Hz a borehole survey applying linear sweeps from 120 Hz to 2600 Hz were executed in 5 m and 10 m steps to image structures around and below the three test wells. Three-component Fresnel Volume Migration were used to image shear wave reflections of the three different wavefield amplification directions
