Designer wells are types of high-angle or horizontal wells that have more than one intended target. This makes them more cost effective because the individual targets would have otherwise required several conventional wells to drain them effectively. One aim of a designer well could be to penetrate and drain more than one fault block. In mature fields, multitarget infill wells can increase the chances of finding an economic volume of oil. For example, in the Oseberg field, Norwegian North Sea, a designer well successfully targeted and lined up several fluvial channel sandstone bodies ([[:file:M91Figure164.JPG|Figure 4]]).<ref name=Rysethetal_1998 />
