Structural interpretation: integrated across the scales

Interpretation and modeling should integrate all available data and relevant analogues, be informed by the regional tectonic context, driving mechanisms, structural style and mechanical stratigraphy and carry multiple models where uncertainty is high. Above all the work should be geared to informing specific subsurface decisions and questions, with delivery focused on addressing the impact on petroleum systems, trap timing/geometry/volume and the structural impact on fluid flow paths and rates.

Establish tectonic setting & plate kinematics.

plate tectonics, basin structural setting

Build regional structural framework, iterative restoration and validation.

Map and 3D model build, validation, assess alternatives.

Moab fault zone, fault juxtaposition, cross fault flow tortuosity, multple slip surfaces

fault surface in core, slickensides, mineralisation, kinematics

Assess fault zone geometry, fault rock types and correlation lengths, fracture populations using core, well logs, outcrop analogues.

$fracture spacing, layer thickness dependency$

Address cross-fault flow unit connectivity scenarios..integrated with reservoir architecture and fault rock properties, upscale to preserve key topology.
