Exceeding 2,500 feet in places, the Wolfcamp's thickness allows for multiple zones of stacked low-permeable pays, translating into millions of additional acres of potential horizontal development when defined in 3-D space. As part of its ongoing effort to optimize completion methods, develop future "stacked lateral" field development strategies, and high-grade exploratory Wolfcamp landing zones from 3-D seismic data, Callon Petroleum Company integrated numerous multidisciplinary measurements on three horizontal laterals in the Southern Midland Basin in West Texas. Drilled in a chevron pattern with stacked laterals vertically spaced at minimal distances, two of the horizontals targeted the deeper Wolfcamp B formation and the other targeted the Wolfcamp A. This empirical approach demonstrates the integration of multidisciplinary measurements to optimize completion parameters with lower costs using stage-by-stage analysis, and to improve fracture modeling workflows for a more complete and accurate solution for optimizing production rates.
