*PERF ( *GEO | *GEOA | *TUBE-END ) well_name
{ location ff (status) (connection) }
*GEO
Well index of each layer is calculated from the geometric information on the preceding *GEOMETRY keyword, the dimensions and permeability of the grid block in which the completion occurs and the partial completion factor
ff. For option *GEOA, geofac = 0.249 is assumed.
Producer 1 is the well_name;
2 3 9 / 2 3 1 are integer or integer ranges specifying the grid block index of the fundamental grid in the I, J or K direction, respectively, through which the well is completed. (See explanation). At most one direction may have a range.
Optional irn, jrn and krn are similar to if, jf and kf, but at the n’th level of refinement (if applicable) for the perforated grid block. At most one direction may have a range.
ff=1.0
The well index calculated in the *GEO option is multiplied by this factor. It can be used to account for partial completions through a grid block. Values of ff must be greater than zero.
