This publication discusses the types of costs associated with well pads that are shared by multiple wells and the concepts that should be considered when allocating those costs. The narrative includes the impact of the 24-month adjustment period, as well as aids in determining which costs should be shared with all wells or subset of wells on the pad vs. costs that are well specific and should not be shared. Allocation examples are provided to illustrate the application of the concepts discussed. 14 pages. 2013.
