The annular space behind the liner may be filled with cement. In this case the cement shall fill to at least 100 feet above the casing shoe, or the top of the liner shall be squeezed with sufficient cement to provide at least 100 feet of cement between the liner and casing annulus. Cement must cover all potentially productive intervals behind the liner. The second completion method which facilitates conventional sand control operations is to hang the liner in the open hole interval below the intermediate casing. In this case the intermediate casing shall be set at, or near, the top of the completion zone. The liner will be run across the completion interval and the liner top will contain a mechanical pack off. The annular space outside the liner may, or may not, contain a sand control material such as gravel or bauxite"... RECEIVED DEC - 6 1990 Alaska 0il & Gas Cons.
