Abstract
Ultra High Resolution 3D imagery has a range of potential application including geotechnical site investigation, shallow reservoir, sedimentary, and smaller-scale complex geological target. Inversion of UHR3D data is rare and technically more limited than methods commonly applied for hydrocarbon prospection. Here we present the results of the combination of a new UHR3D system with the Genetic Algorithm inversion of Vardy (2015) to obtain physical properties of a complex shallow water target. The UHR3D volume provides high quality imagery of isolated point target and complex geological landforms, which associated with the acoustic impedance inversion algorithm allows to derive quantitative information regarding the nature of the channelized target at a resolution not previously possible.
