3D Basement and Interface Topography TerraNotes had researched and developed new technologies for mapping the basement topography using gravity (gGase ™) and/or magnetic (gGase ™) data. Main Benefits of these technologies:
- Provide
a powerful additional constraint to validate the tectonic, structural and stratigraphical
models initially derived from well data and seismic control.
- Extrapolate
structural trends beyond the seismic data coverage.
- Resolving structure under low-density section e.g., salt
- Resolving structure at the sedimentary/igneous interface
- Increase the value of proposed seismic studies
Regional analysis to identify areas of interest
- Lithology
of crystalline basement and structures
- Structural
relief of crystalline basement (3D shape including elevation)
- Fault
location and distribution (type, strike, length, dip and depth)
- Identify
and characterize salt domes (location, size, height, 3D shape)
- Delineate
igneous rocks (area, overall depth/thickness, lithology interpreted)
Petroleum geology of sedimentary basin
- Petroleum generative depression
- Block sag
- Hollow zone
- Mobile geosynclinal
trough
- Topographic
depression
- To map sedimentary depression and local structures related:
- Burial hill and
anticlines of above formations
- Local
structures in Paleogene formations
- Fault
traps
- Formation
overlapping and pinchout on uplift flank
- Flexure
caused by deep faulting
