A case history is presented on reservoir simulation of a giant; complex; low-permeability; carbonate reservoir completed with many long horizontal wells. The multiple radial layouts of 75 very long horizontal wells in the field posed a challenge in modeling individual-well performance with a manageable grid size and acceptable run time for history matching. The gridding dilemma was solved by use of 2.5D perpendicular-bisector (pebi) grids around each individual wellbore. This method provided sufficient resolution between wells and aligned the grid with the well paths; thereby avoiding grid nonorthogonality issues.
