WebThe borehole P-S seismic suspension logging probe has been designed for this purpose and can provide these measurements from inside PVC casing. ... Previously, these parameters could be calculated using the fullwave sonic probe but in uncompacted, near surface sediments the shear wave was very difficult to pick. WebJan 18, 2024 · This causes the mandrel of the logging device to center in the borehole; thus, it is typically used with sonic tools for centralization. This device reports the shortest of the three measurements and frequently collapses under tool weight in deviated boreholes. The four-arm device is typically used on a dipmeter.
