Abstract
The production of oil from the Troll Field in the North Sea has been studied numerically by Kossack, Kleppe and Aasen (1987). The reservoir description used in that study contained low-permeability layers of cemented sandstone at the gas-oil contact and below the water-oil contact. The lateral extent and continuity of these cemented layers and the exact value of their vertical permeability is unknown. As a result, the comparisons between the vertical and the horizontal well performance in the Troll Field as presented by Kossack et al. (1987) is only valid for the particular description used.
