NALU™ Near-Wellbore Modelling

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.

Evaluating Partially Completed Liner Performance

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.

Experimental & Computational Nozzle Testing

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.

This infographic visually shares an analysis based on reservoir simulation. We used CMG-STARS software to match the well's history and then ran simulation to mimic the performance of the well after the installation of flow control devices (FCDs).
