Modeling a Subsurface Formation Using an Unstructured Grid

Abstract: systems and methods for modeling a subsurface formation include obtaining geological data and petrophysical data from the subsurface formation; forming an unstructured grid representing the subsurface formation by determining locations for nodes of the unstructured grid and connecting the nodes to other nodes in the unstructured grid using connectors. the lengths of the connectors are based on distances between the nodes and boundaries of the unstructured grid. geological and petrophysical properties are assigned to the nodes based on the geological data and petrophysical data; permeability values are assigned to the connectors based on the petrophysical data. a volume of fluids in the subsurface formation is estimated based on the lengths of the connectors of the unstructured grid and based on the geological and petrophysical properties assigned to the nodes and the permeability values assigned to the connectors.
