Downhole library of master wavelets for VSP-while-drilling applications |
摘要 |
A controllable seismic source is used in a seismic-while-drilling system for obtaining VSP data. Coded information is sent downhole about the signal generated by said controllable source. The information about the seismic source is used for reconstructing the source waveform and processing the VSP data. Optionally, a reference signal measured at one depth of the BHA is used for processing of signals at subsequent depths.
