... as the well so that the well block pressure can be considered as the wellbore pressure. This eliminates the need for using a well index. However, our analysis shows that the non-uniform fine grid used for explicit modeling of wells, as reported in a recent paper, can lead to incorrect results. This is mainly...

... Abstract A novel procedure is proposed for a quick and accurate evaluation of bottomhole wellbore pressure and productivity index. The procedure has led to simple correlations for both horizontal and vertical wells which can be applied to calculate the bottomhole wellbore pressure...
