The initial reservoir pressure map was created by averaging the shut-in pressures from DST tests carried out across the producing zones in each well. The pressure map showed that most of the field had an average pressure of more than 1100 psi. There were two pockets of low pressures (in the range of 400 psi) at the periphery of the field. The pressure map was normalized such that no grid block had a value less than 1100 psi.
