From September 1985 to January 1987, Standard Alaska Production Co. (SAPC) drilled eight nonconventional (horizontal or high-angle) wells at Prudhoe Bay. Typical well profiles are shown. Drilling techniques used in the first three wells are described elsewhere. Liners were cemented for zonal isolation in seven of the eight non-conventional wells. Cementing techniques included off-bottom cementing of 7-in. liners for gas cap isolation; simultaneous rotation/reciprocation of liners while cementing, and strategic placement of a cement-filled formation packer between the gas/oil contact and the oil producing interval. The liner cementing techniques used on the seven wells are detailed herein. Results are evaluated by reviewing cement evaluation logs and production data. Since January 1987, seven additional horizontal or high-angle wells have been drilled and completed with cemented liners. These last seven wells are not included in this article, other than to reference the longer liner lengths that recently have been cemented and perforated.
