Abstract
A method for reducing longitudinal flow of fluids through an annular space surrounding a permeable well tubular, such as a slotted liner or a sandscreen, in an inflow region of an oil and/or gas production well having: arranging a series of collapsed resilient sealing rings at regular longitudinal intervals around the permeable tubular before lowering the tubular into the well by means of tape and/or a binder which dissolves downhole; placing the tubular in the inflow region of the well; and allowing the tape and/or binder to dissolve, thereby allowing the resilient sealing rings to expand radially in the annular space surrounding the permeable tubular.
