Popis: Technology Focus Making the Good Completion Better The ability of operating and service companies to optimize completion results from standard completion configurations through better reservoir-fluid management has been enhanced greatly by the development of advanced completion hardware [i.e., inflow-control devices (ICDs)]. These devices enable us to “fine tune” flow from individual pay zones that are over- or underpressured. Field performance of wells equipped with ICDs and multisegment-well modeling, including ICDs, have indicated measurable advantages over conventional completion systems. Industry also developed perforating-gun modules that can be configured to perforate the formation in any desired orientation. As each gun module is fired, a flapper valve is actuated to isolate the newly created perforations from the lower, previously stimulated zones. This process ensures accurate and efficient proppant placement. An operator’s goal is to reach production faster, with the widest assortment of specialty tools and hardware, which have been improved continuously over the past decade. Today, many operators use multilaterals, which enable maximum reservoir contact with minimum surface requirements and can accommodate a wide range of completion options. Whether the play is a conventional shallow-gas or deep-gas reservoir or an unconventional-oil/-gas reservoir, use of these technologies can increase production while improving project economics. Reliable and field-proven completion solutions enable creating the ideal conduit from pay zone to surface, regardless of well type or operating environment. This is the key to getting the greatest return on field-development investment and to minimizing life-of-well cost. This overview will not attempt to refer to all new well-completion technologies, but only to highlight a few important recent developments and concepts. Nevertheless, as one searches the literature, the importance of JPT’s role becomes obvious from the large number of references and papers cited with relevance to significant technical achievements in the upstream petroleum industry. There are many papers about technological advances, and I congratulate respective authors in bringing their papers to fruition. Finally, I hope you enjoy reading the selected papers as much as I did during review and selection for the feature.
