Abstract

It is well-known that the drill-bit vibrations can be successfully utilized in a modern geophysical practice. A use of the MWD (Measure While Drilling) methods appears to be quite promising not only due to a reduced cost of a data acquisition but also because of no hazardous to wells equipment is needed. These advantageous properties permit one to collect large volumes of data at relatively low cost that would be otherwise prohibitevely expensive. It is quite intriguing, though, to use large data sets to accurately infer the interval Barth structures using the drill-bit vibrations. In this work, we report a feasibility study for the reverse VSP traveltime tomographic inversion using the first breaks of the recorderf data. The inferred compressional velocities can be subsequently used in a drill-bit migration. This work is a part of a research Project jointly carried out by the OGS and the AGIP .
