| Downhole Borehole Seismic Hammer & 3D Geophone Sensor |
This
downhole hammer has been approved by the ASTM for use in generating
subsuface S waves from a source to a seismic receiver unit. To my
knowledge it is the Only ASTM approved device on the market at this
time. It is generally used for distances of less than 10
meters between boreholes and can generate both P wave and S(Shear)
waves for use with sub surface velocity engineering studies. The
above source can descend down a borehole to 200 feet and is
approximately 2.75 inches in Diameters. It is a relatively light
weight system and is also portable.
Pictured to
the left is the downhole borehole sensors which are used in
3D configuration to detect signals generated by the downhole hammer
above.
