Hydrocarbon reservoir testing

摘要

A reservoir in a payrock (2) is analyzed using finite element simulation. A reservoir engineer selects an appropriate model from a set of template models, each comprising a set of polygons (51) in plan and layers (53) in elevation. The polygons are defined in objects instantiated from classes by control points and the layers as depth values of control points. A pattern object sweeps rotationally about a wellbore in a wellbore polygon to define a pattern of elements, fewer in number with distance from the wellbore. A polygon object also sweeps linearly from a generator line in the direction of a base line. The generator and a base lines correspond to polygon boundaries. Finite element simulation is performed with the model so derived.
