Abstract

Building a fault network is the first stage of reservoir modelling and complex fault networks can be tiresome to build when there are many faults with multiple contacts. This paper presents results obtained with a new methodology developed by a Paradigm team for fault network modelling . Instead of building triangulated surfaces, detecting fault contacts through geometrical tests and projecting fault borders to create watertight contacts, faults are modelled implicitly as level sets of a function. The function is computed from any kind of fault data. Fault contacts are detected and honoured automatically. An editing step can be performed on the suggested fault network: fault shapes can be altered and fault contacts can be modified. All updates are performed in real-time on the fault network. A block model of the fault network is then built automatically from the implicit fault network; the block model can be queried for fault and fault contact geometries and for topological requests such as which block a given point belongs to.
