These images represent a true volume of spatial data collected and processed at the same instant. Coda Octopus’ phenomenal leap from 4D to 5D and 6D capability sees a seismic shi to each ping generated, now returning over 1.6 million data values instead of the previous 16,384. Our new 5D and 6D sonars allow customers to do multiple things with these sequential 4D volumetric images including full-time series data with the parallel processing of each ping. Alongside Schiehallion this new technology comes the ability to capture raw data and perform post acquisition beamforming of data. BP has announced early production from the Alligin is part of BP’s advantaged oil strategy, Alligin field in the west of Shetland region. a development with a shorter project cycle time with oil that is economic to produce and Alligin forms part of the Greater Schiehallion low risk to bring to market.
