Legacy seismic data are sparsely located and are of variable quality (expensive and difficult - to acquire in harsh terrain)
Surface geology masks the deeper structure
Thrust environment complicates the shallower velocity model
Regional data lacking in resolution
Method
Airborne gravity gradiometry (FTG) and gravimetry (GMA)
Airborne Magnetics
LiDAR
Solutions
Integration of complementary geophysical datasets to produce a structural map of the main
Thrust zones and lateral ramps
Depth-to-source estimates
2D section forward modelling of varying scenarios
3D Shallow Earth Correction
Geology
Regional inverted Late Triassic rift system resulting from the breakup of Pangea, with subsequent deposition of Mesozoic marine and Cenozoic continental sediments.
Transpression-induced faulting and folding facilitated the structural inversion of the basin
The survey area is characterised by a thrust belt and foredeep basin
Objectives
Provide information to assist in further seismic acquisition locations
Subsurface imaging of thrusts and the deeper basement structure
