Borehole 3D Geophones GFA 60/100

GFA down-hole 3D geophone has three 10Hz geophones - oriented according to the x-y-z axis -housed inside a cylindrical probe for the determination of the time of arrival of the type 's' and type 'p' seismic waves. The piston wall-clamping device can fit drilling well of a diameter between 50mm and 110mm (larger diameter on request). The mechanic clamping system with pneumatic piston can couple rigidly with the well casing, so to reflect seismic real signals at the best, avoiding the trouble of lacerating gasbags typical of most low-cost systems. The probe has a robust cylindrical metal case that can assure a long use in field conditions; the special signal cable (graduation 1m) and the air tube are delivered on a special reel, for a total weight of less then 15 kg (GFA-60).

Cable Lenght: 60/100 meters

Data Inversion Software are also available.

Energizer P-S CROSS HOLE

Specially designed for small-scale cross-hole surveys, this compact hammer can be used to generate both P and S waves

The hammer can be downloaded using the steel cable and clamped to the requested depth by a pneumatic clamping system manually controlled by a lever from the surface; simply pushing up the steel cable to execute the first shot, the trigger installed on the energizer will start the acquisition for the “P/S”. After that you will have to drop the mass to make the acquisition...
