Stepout-Deepening Wells

A well drilled at a later time over remote, undeveloped portions of a partially developed continuous reservoir rock. A deepening well is reentering a well and drilling to a deeper reservoir. Often referred to as an "infield exploration well" in the oil and gas industry.[1]

Also Known As
delayed development well


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.)
