143066 – Optimization of Completions in Unconventional Reservoirs for Ultimate Recovery – Case Studies


The two main methods of horizontal, multi-stage completions currently used in unconventional reservoirs are: cemented liner “plug and perf” and open hole, multi-stage fracturing systems. This paper describes the main methods of horizontal, multi-stage completions, and discusses how the choice of method can affect good fracturing practices as well as long-term production. Case study examples are presented from a variety of unconventional reservoirs included including shale, tight sandstone and carbonate formations.
