Least-squares RTM (LSRTM) showed some good improvement over the RTM but proved less effective where the starting image was too poor. Cross plots are also made here and zones of interest defined. It is started from Geoview and used to edit and average logs.

The E log is the well log editing and modelling tool embedded within the Hampson-Russel software suite of applications.

However, despite these large improvements, the image still suffers in areas of low illumination. Well log data are loaded into Geoview well database through the Well Explorer. The OBN TLFWI model combined with the long offsets of the OBN data allowed steeply dipping events along the salt feeder to be seen for the first time on the reverse time migration (RTM) image. While the velocity model obtained from Time-lag FWI (TLFWI) using the legacy rich-azimuth (RAZ) streamer data provided significant imaging uplift over the best previous processing, an additional step-change improvement in image quality was achieved by running TLFWI with the OBN data. Recent advances in full-waveform inversion (FWI) algorithms combined with a newly acquired, ocean bottom node (OBN) data set have ushered in a fundamental shift in velocity model building and imaging at Shenzi as we move away from mostly interpretation-driven to more data-driven processes. Paradigm shift: Recent advances in model building and imaging at ShenziДЄfter many years of processing seismic streamer data acquired over the Shenzi field in deep-water Gulf of Mexico (GOM) with the best available technology, the workflows have remained highly interpretive, far from robust, often time-consuming, and ultimately proved inadequate for resolving the complexity of the salt and subsalt velocity models.
