Step-out-well: a well drilled in the expected extent of a reservoir that is being developed but at a significant distance, usually two or more drilling and spacing units, from the nearest producer in that reservoir. A step-out well is sometimes called an out-step well (Norman J. Hyne, 1991. Distionary of Petroleum Exploration,Development and Production,Penwell Books, 625p.)
