Transverse Fault Throw Uncertainty Assessment: Latest Advances

@inproceedings{P103_Corbel,
 abstract = { Characterization of fault displacement is difficult, yet consequential for understanding
fault transmissibilities or enhancing quality of structural models. In this work, we propose
to study the uncertainty about the transverse component of the fault throw vector, to
optimize its direction.
Each fault block of a horizon is unfolded separately without taking faults into account,
in order to separate the effects of unfolding and unfaulting in horizon deformations. Then,
using a sequential Monte-Carlo sampling, several fault displacement models can be
generated, to therefore select a set of best models of fault displacements. The proposed
method perturbs the links across fault gaps on a horizon so as to make the transverse
displacement variable. For each new displacement field, the horizon is restored, and
deformation analysis is used to assess the likelihood of the fault displacement. The Monte-
Carlo sampling technique being reputably slow, this optimization problem is solved locally
for all faults, to obtain a set of possible models efficiently. },
