... monitoring. Thus, whether sim-source acquisition is feasible for 4D remains a long-standing question. In 2019, bp took the step forward by acquiring the first sim-source ocean bottom node (OBN) monitor survey at the Atlantis field in the Gulf of Mexico (GoM). With 4D-friendly deblending and matching...

... The Thunder Horse baseline Ocean Bottom Node (OBN) seismic survey was acquired in 2015 followed by the first monitor survey in 2020. The goal of the time lapse survey was to reduce sweep uncertainty due to water injection, aquifer influx and compartmentalization. Fast track 4D seismic results...

... sampled and not replicated to reduce costs. As a result, images obtained for different vintages (baseline and monitor surveys) often contain artifacts that may be attributed wrongly to time-lapse changes. To address these issues, we propose to invert the baseline and monitor surveys jointly. By using...

... for the monitor survey. The method uses Proper Orthogonal Decomposition (POD) to extract the basis from the training dataset. The base survey provides the training dataset to estimate the POD. Instead of using a conventional universal basis, the POD basis extracted from the base survey provides a data...

Improved repeatability of 4D monitor surveys can be achieved by applying deghosting and datuming via seismic wavefield separation. By also correcting for the variable distance of the source above...
