LogDB ODP/IODP Sonic (re)processing
This utility was initially developed for the 2021 ECORD Summer School as an introduction to acoustic processing. While most sonic logs recorded by the DSI tool for IODP are of good quality, some holes did not provide the optimal conditions for the DSI, because of poor hole conditions or of environments very different from the oil fields for which the DSI was designed. This utility provides a way to assess the quality of any of the DSI logs in logDB and to reprocess the waveform to improve the velocity logs when necessary.
First select an ODP Leg or IODP expedition:
then choose a hole from that leg/expedition:
