Unsteady-State Pressure Response in a Slotted Liner
Abstract/Contents
- Abstract
- A semi-analytical solution has been obtained for the unsteady-state pressure response in a slotted liner. The solution was obtained by means of a source function, assuming constant rate of production, penetration ratio of 0.5 (i.e. ratio of total open interval to total thickness) and various slot lengths (no storage or skin effects were considered)For integration purposes, satisfactory results were obtained using Simpson's rule. The results show that inside and outside the slotted liner, the pseudo-skin factor due to restricted flow to the well is negligible for 6 vertical rows of slots (3 pairs of vertical staggered rows, or 3 slots in one ring of slots), even at early time of production. On the other hand, on the surface of the liner, there is a pseudo-skin factor, unless the number of rows is increased.There is not much difference in pressured drop in a liner with many and short slots, as compared to a liner with a fewer and longer slots, but with the same number of vertical rows.
