NEW CAPABILITIES OF THE SONIC LOGS SET FOR OIL WELL LOGGING
An example of applying a sonic waveform logging in slim holes (78 to 103 mm in size) has been considered. The pilot specimen tests have shown that this tool can also provide qualitative measurements in 240-mm size wells. The additional capabilities of the log can be implemented by combining different sonic log modifications. In particular, the capabilities of a set of the waveform logging and a high-frequency sonic sounding for solving problems in fractured reservoir intervals identification have been considered.
