Claim One:
1. A computer implemented method for developing wellbore plans with a reservoir simulator, comprising: identifying connected grid cells in a gridded reservoir model that meet a preselected filter range criteria comprising reservoir performance values; creating a drainable volume indicator for each group of connected grid cells that meet the pre-selected filter range criteria by eliminating connected grid cells within each group of connected grid cells that do not meet a minimum predetermined permeability and mobile oil fraction within a specified radius; calculating an adjustment value on a computer system for each drainable volume identified by each drainable volume indicator; selecting each drainable volume that has an adjustment value up to a predetermined maximum adjustment value and designating each selected drainable volume as a completion interval grid; and connecting contiguous completion interval grids on the computer system to form one or more completion intervals.
