Until recently, wells targeting thin injectite sands in the North Sea have often failed to deliver reasonable reservoir exposure. These thin sand reservoirs form through post-depositional remobilization and injection along various zones of weakness. On seismic sections, cross-cutting injection "wings" can even look like processing artifacts. As a result, determining the exact stratigraphic location of reservoir boundaries and fluid contacts is almost always subject to uncertainty. Traditional methods of optimizing well placement, under such conditions, suffer from critical limitations.
