Downhole & Crosshole
Features of Downhole & Crosshole
- Obtain Vs and Vp values of rock and soils at a point surrounding a borehole
- Multiple boreholes (up to 4) can be cross measured to create a 2D or 3D profile
- Used in areas where surface access is restricted
- Produce elastic modulus tables of shear, young’s, bulk and poissons ratio
- Very deep studies are possible, up to 300 meters
- High resolution crosshole profiles between two boreholes detect extents of voids or other hidden features
