the remainder of the producing interval can be selectively produced as one example the restrictor 13 can consist of a permanent bridge plug installed at any point in the liner or casing between points 1 and 2 if the intent is to permanently block the wellbore alternatively the restrictor can be a temporary plug set in any number of casing profiles pre installed in the well liner or casing although this is less preferred such temporary plugs can would be installed via coiled tubing snubbing unit or workover rig the restrictor 13 can optionally be designed to only partially restrict the production of fluid and thus cause only a relative decrease in production from the area behind the flow restrictor for example one or more permanent packers equipped with a flow restricting orifice could be installed at any point between 1 and 2 a retrievable orifice could also be installed in one or more liner profiles which would be placed at preselected points in the production liner referring to an optional embodiment of the invention shown in fig1 a secondary zone such as the interval between points 18 and 19 is also completed for oil production usually when production from the primary zone between 15 and 16 must be severely restricted or abandoned if all of the primary zone area is to be abandoned the well can be plugged back at a point between 15 and 19 or even higher abandonment of the inverted section is preferably accomplished by.
