data modifications required to correctly model symmetry in a 1/4 or 1/8 5-spot model using block-
centered gridding - ANSWERS-lay out grid so that wells fall in the center of cells
-apply pore volume and transmissibility multipliers
-divide well PI's and flow rates by 4 or 8 to account for modeling less than a full well
(waterflooding) laying out grid sot that the wells fall in the center of the cells is required for -
ANSWERScorrect calculation of well PI's using Peaceman formulas
(waterflooding) area modeled is too large since - ANSWERSlines of symmetry go through well centers
