Abstract

A compaction and/or hydro fracture generation device ( 10 ) comprises a compression device ( 11 ), a vibration generator device ( 12 ) arranged to generate vibrations in the ultrasonic frequency range, and a power source connected to the vibration generator.

Claims

exact text as granted — not AI-modified
1 . Subsurface material compaction device comprising:
 a compression device,   a vibration generator device arranged to generate vibrations in the subsurface material, which vibrations are in the ultrasonic frequency range, and   a power source connected to the vibration generator.   
     
     
         2 . Compaction device according to  claim 1 , where the compression device is a moving piston plate. 
     
     
         3 . Compaction device according to  claim 2 , where the vibration generator device is a sonic or ultrasonically vibrating surface that is affixed to the moving piston-plate. 
     
     
         4 . Compaction device according to  claim 1 , where the compression device is a plate connected to or integrated in the vibration generator device. 
     
     
         5 . Compaction device according to one of the previous claims, where the vibration generator device is connected to the compression device and arranged to generate vibrations in the compression device. 
     
     
         6 . Compaction device according to  claim 5 , where the vibration generator device generates high-power vibrations of >1 kW and >8 kHz frequency. 
     
     
         7 . Compaction device according to  claim 5 , further comprising a controller unit connected to the vibration generator to control the vibration generator. 
     
     
         8 . Compaction device according to  claim 5 , where the vibration generator is a piezoelectric or magnetostrictive transducer. 
     
     
         9 . Compaction device according  claim 5 , where the vibrations are in the area 20 kHz and above.
