Abstract

Summary

Near Field Hydrophone (NFH) data are routinely collected during marine acquisition and historically these data were used to QC air-gun timings and/or other air-gun-related issues. More recently (last 10–15 years), these data were recorded and employed during processing to aid both 1D and 2D source-signature deconvolution. The results presented here demonstrate it is possible to obtain a high-resolution image (greater than 100 Hz) of the near subsurface (0–1 s) using passive NFH array data. Similar results are also achieved with the active NFH array although noise handling in processing is more difficult. NFH data for imaging, can be a natural by-product of conventional marine seismic acquisition, with minimal additional processing cost. Potential uses could include: replacing requirements for a high-resolution 2D acquisition for site surveys, utilizing a source-only vessel for localized overburden and reservoir 4D monitoring, as well as improved deghosting and integration with distributed acoustic sensor vertical seismic profile data.
