  • Open-hole, multi-stage verticals surpass conventional plug-and-perfs in Permian basin

    Darrell Lohoefer, Brett Keener, Dj Snyder, Saiff Ezeldin and Cliff Wohleb

    The Permian basin is one of the top five resource plays in the U.S., attracting a high volume of activity from operators. This unconventional trend consists of several stacked pay zones, and the shale and carbonate layers act as barriers to fracture growth, making well completions a challenge. While horizontal completions in the shale layers are in the initial stages, operators are successfully exploiting the reserves through vertical wells. Figure 1 illustrates the Permian basin, and, specifically, the formations in the Delaware basin that are the focus of this article.
