Abstract

This paper introduces a workflow which constructs a tetrahedral mesh radially organized around well polylines and performs continuous transition with the global tetrahedral mesh of a 3D geological domain. Two data types are used to constrain final mesh generation. The first input is the geometry of model elements: triangles of surfaces and polylines corresponding to surface contacts and well paths. The second input is a scalar mesh size property associated with the model elements. The final mesh fully conforms to the geometry of the input elements, including wells. The size of the mesh tetrahedra is governed by the mesh size input property, continuously changing from the boundaries to the inner part of elements. The mesh around wells consists of a regular part and a transition zone. Well mesh size controls the regular radial mesh around wells, and well effective radius determines the radius of a zone of gradual transition between the regular local well mesh and the global domain mesh.
