Abstract This paper describes a system that autonomously minimizes production losses caused by upset events at the central processing facility (CPF) by restricting well production using automated choke valves and/or at the central gas-lift compressor (CGL) facilities by adjusting surface gas-lift injection …

Abstract Significant value can be achieved by optimizing production of a gas-lift network. Operators have traditionally performed this work manually using network models, but maintaining these models is often labor-intensive. To address this challenge, a closed-loop optimization system was developed that leverages …

Abstract A major challenge during drilling is to identify sub-formation change, enabling near-real-time adjustment of the drilling parameters to enhance performance. An algorithm that determines sub-formations and optimizes drilling parameters as formations change and then updates itself solves this problem. This paper …

Summary With the recent advance in high-speed data communication offered by wired-drillpipe (WDP) telemetry, it is now possible to design automated control systems that directly use downhole data (e.g., pressure) to optimize drilling procedures. This research couples drilling hydraulics, rate of penetration …

Summary Low-latency feedback, high bandwidth, and improved sensor placement are key benefits provided by wired-drillpipe (WDP) technology. Improved WDP reliability, based on more than 100 wells of field experience, enables more-aggressive application of the technology, including closed-loop control of drilling processes. Often, …
