Abstract
An unstructured grid model with actual well trajectory of individual multilateral wells of a subsurface reservoir is formed. Well trajectory data obtained during drilling of the wells and corresponding to well trajectory data stored as a structured grid model is provided as an input data set for unstructured grid simulation. The unstructured grid model may be formed in a computerized mainframe processor system, or by parallel reservoir simulation by processor nodes of a multicore processor of parallel processor nodes synchronized and under control of a master node.
