Abstract Projection-based embedded discrete fracture model (pEDFM) is an effective numerical model to handle the flow
in fractured reservoirs, with high efficiency and strong generalization of flow models. However, this paper points
out that pEDFM fails to handle flow barriers in most cases, and identifies the physical projection configuration
of fractures is a key step in pEDFM. This paper presents and proves the equivalence theorem, which explains
the geometric nature of physical projection configurations of fractures, that is, the projection configuration of
a fracture being physical is equivalent to it being topologically homeomorphic to the fracture, by analyzing the
essence of… More >
