A RAPID METHOD FOR RESERVOIR CONNECTIVITY ANALYSIS USING A FAST MARCHING METHOD

摘要

Methods for analyzing the connected quality of a hydrocarbon reservoir aredisclosed. A model of a portion of the reservoir is divided into cells, eachcell having a volume and some attributes, and wherein a speed function isassigned to a portion of the cells. A reference cell is chosen. A connectivitybetween cells in the reservoir is determined by solving an Eikonal equationthat describes the travel time propagation, said propagating front progressingoutward from a reference cell until an ending condition is met, said Eikonalequation being solved by a fast marching method with propagation velocity as afunction of spatial position being provided by the speed function. Regions ofthe reservoir are characterized by their connective quality to the referencecell using the connectivity.
