PETREL
Seismic & Structural Interpretation
A practical Petrel workflow covering seismic display, horizon picking, fault construction, structural surfaces, attribute review and integrated three-dimensional checks.
WORKFLOW
Seven stages from seismic display to structural framework.
STAGE 1
Seismic sections and horizon picking
Review reflector continuity and place horizon picks consistently across seismic lines.
STAGE 2
Display setup and visibility
Adjust colour, opacity and panel layout so interpreted reflectors remain clear.
STAGE 3
Horizon surfaces and section tie
Compare section picks with generated surfaces and check their spatial relationship.
STAGE 4
Fault sticks and fault surfaces
Build fault sticks from interpreted discontinuities and review the resulting fault geometry.
STAGE 5
Surface morphology and attributes
Inspect structural-surface form, colour ramps and attribute patterns for irregularities.
STAGE 6
Integrated seismic–surface framework
Review seismic panels, horizons, surfaces and faults together in one three-dimensional scene.
STAGE 7
Structural framework and grid preparation
Organise the interpreted faults and horizons before moving into the structural-model grid workflow.
