RGL has developed its own in-house near wellbore simulator, named NALU™, dedicated to Flow Control Device (FCD) design. NALU™ is a low-overhead simulator that relies on limited input, provides results within minutes, and uses physical conservation equations rather than empirical relations to determine state-property profiles. Furthermore, NALU™ captures the majority of thermofluidic physics ignored in classical wellbore simulators. With this tool, engineers at RGL can quickly iterate on a wellbore design and reliably identify relative improvements.
Using state-of-the-art computational fluid-dynamics (CFD) software packages, RGL engineers have developed simulations to predict the additional pressure drop incurred from partially completing a wellbore’s liner. The simulation allows RGL’s engineers to contrast the cost savings of a partially completed liner against the additional pressure-loss disadvantage, and in turn select a partial completion that strikes a balance between these competing factors.
RGL engineers are expanding there in-house testing capabilities to evaluate increasingly complex flow situations experienced by FCD nozzles. Currently, RGL engineers can simulate and experimentally measure the performance of nozzles impinged by single-phase flows and are now developing apparatuses and models to evaluate nozzle performance during multiphase flow.
RGL provides a comprehensive range of engineering, technical, product design services for the oil and gas industry. Maximizing efficiency through all phases of projects, from planning and design to construction and operations, is RGL’s specialty. Our multidisciplinary teams deliver cost-effective solutions and a hands-on approach to ensure project success.
