In a wellbore (1) provided with a non-cemented perforated liner (6) forming a continuous annular space (7) between the liner and the formation (2), the liner having an original perforation pattern being optimized for acid stimulation of the wellbore, the following steps are performed: injecting a hydrocarbon displacement fluid and measuring parameters relevant for inflow profiling, on the basis thereof, determining an actual inflow profile (Pa) over the length of the wellbore, comparing the determined actual inflow profile (Pa) with a preferred inflow profile (Pp) over the length of the wellbore, estimating, on the basis of the difference between the actual inflow profile (Pa) and the preferred inflow profile (Pp), a modified perforation pattern for the liner, determining how the original perforation pattern of the liner may be adapted to form said modified perforation pattern for the liner, and adapting the perforation pattern of the liner accordingly. |
