Tunnelseis offers seismic processing services in the area of tunnel seismology and beyond.
Our expertise may be particularly interesting to clients
who (1) appreciate a careful data analysis and processing that honours the character of the
data to aim at the best result
and who (2) do have a data set with poor signal quality and high noise level.
We do not simply pipe the data through a standard processing flow.
Instead we may build the optimum processing flow for each particular data set.
This can mean that new processes have to be developed or available processes have to
be combined in a new way. Both can be done quickly because over the years we build
a big tool-box of modules and special purpose subroutines that we can combine freely
Our reflection seismic processing capabilities allow anything between a standard processing flow centering around CMP-gathers and NMO-processing and a most advanced automatic pre-stack migration residual moveout analysis for velocity analysis in a standard or in a tunnel seismic geometry. Many single channel and multi channel filter operations can be included in the work flow, several are not available elsewhere. Discrimination between desired signal and noise is among our specialities along with amplitude preservation. We have several options to compute traveltimes and to invert them or to use them for imaging in two or three dimensions. Seismic attribute analysis and geostatistical techniques like kriging may support the interpretation. Borehole logs, vertical seismic profiles and similar data or refractions may all be processed and analysed by Tunnelseis.
Here are the principles that guide our processing work at Tunnelseis
