ARCO Alaska has developed a procedure to calculate total pore foot values directly from seismic amplitude, where pore foot is defined as reservoir thickness times average porosity. This was accomplished without an intermediate net pay map or average porosity map. The procedure was applied to the Lisburne Pool, a carbonate field located on the North Slope of Alaska. The upper Lisburne is Pennsylvanian in age, and stratigraphically separated from the overlying Permian-Triassic Sadlerochit formation. Structurally it lies on the crest and the southern flank of the Barrow arch. The field is bounded on the north by the major North Prudhoe Bay fault, truncated to the east by a major Cretaceous unconformity, and limited to the south and west by a variable oil-water contact. A porosity cross section through the area (Figure 14-9-1) shows the porosity is highly stratified and highly variable laterally. This makes porosity prediction difficult from wells alone.
