Technical Abstract

Estimation of water layer correction in shallow time-lapse streamer data sets

Back to Technical Content
Time-lapse seismic surveys are intended to measure changes in the subsurface related to reservoir production. Accurately estimation of the reservoir-level requires prior corrections to layers above the reservoir, including the water layer. Water layer changes can be attributed to ocean tides and water velocity changes, which require offset- and depth-dependent timing corrections. These can be difficult to estimate in shallow water marine streamer data sets; thus we developed a completely data-driven method that reduces timing differences and is effective in both shallow and deep water.
