ARKeX FTG and ION GulfSPAN
ARKeX and ION worked together on a Full Tensor Gravity Gradiometry (FTG) survey to construct an interpretation of geologic fabric along the Louisiana coast while assisting with the building of seismic velocity models.
- 3100 square mile survey
- Transition zone of the coast of Louisiana
- Combines Full Tensor Gravity Gradiometry with ION GulfSPAN
The joint interpretation and integration of the FTG data with ION's GulfSPAN data is the key to an improved imaging of the Louisiana coastal region. GulfSPAN data delivers an improved understanding of the regional geology and the deeper, less explored areas of the basin.
This joint project aims to further improve the interpretation along each line and help extrapolate the interpretation between lines to produce a geologic fabric of the region. Particular attention is paid to the Miocene and Sub-Miocene growth fault systems, which are well mapped on the GulfSPAN data but unconstrained between seismic lines. Gravity Gradient data is used to improve the velocity modelling in the reprocessing of existing lines and the processing of any new onshore GulfSPAN lines.
- Mapping faults between 2D Seismic
- Building an enhanced seismic velocity model
- Mapping through areas with reduced seismic data coverage
