GasGuard®

Tackle Gas Slugging Before It Disrupts Production

Gas slugs can form under a wide range of production conditions, whether due to shifting reservoir dynamics, enhanced oil recovery (EOR/IOR) strategies, or fluctuating production rates. Regardless of the cause, slugging remains one of the most persistent and costly challenges in the oil and gas industry.

This issue is particularly critical in unconventional wells that utilize artificial lift technologies, such as electric submersible pumps (ESPs). Gas slugs can lead to lost production, equipment damage, and increased operational costs, ultimately delaying the incremental production that optimized ESP systems are designed to capture.

The Best Solution Is Prevention

That’s where FET Multilift Solutions steps in. Our patent-pending GasGuard® neutralizes gas slugs before they reach the ESP system. By breaking down and infusing gas slugs into the liquid stream, GasGuard ensures a smooth, uninterrupted flow through the pump. The result? A more stable production stream with higher liquid content, improved motor cooling, and enhanced ESP performance with fewer shutdowns and lower maintenance costs.

With its streamlined, no-moving-parts design, GasGuard sets a new standard in gas slug protection.

NALU™

NALU™ NEAR-WELLBORE MODELLING

NALU™ is a multiphase flow dynamics wellbore simulation proprietary software. The software can conduct multiphase flow dynamics simulation in the near-wellbore regions to mimic various sand control and flow control completions methods. Unlike the commercial software on the market, NALU is based on the fundamental Navier-Stokes Equation with minimal reliance on the empirical correlation. Therefore, the fluctuations between neighboring flow regimes caused by the empirical relationships, as observed in the other commercial wellbore simulators, will be eliminated.

NALU has been utilized as an efficient flow control design tool for various applications including tubing deployed and liner deployed inflow and outflow control devices for both conventional and unconventional operations. Various sand control screens can also be accounted for in the simulation. The key outputs of the model are the radial mass flow rates across the nozzles and pressure drops associated with the specific nozzle distribution.

EVALUATING PARTIALLY COMPLETED LINER PERFORMANCE

Using state-of-the-art computational fluid-dynamics (CFD) software packages, Variperm engineers have developed simulations to predict the additional pressure drop incurred from partially completing a wellbore’s liner. The simulation allows Variperm’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

Variperm engineers are expanding there in-house testing capabilities to evaluate increasingly complex flow situations experienced by FCD nozzles. Currently, Variperm 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.
