The capabilities of multiphase flowmeters allow for optimization of all types of critical production enhancement techniques. Gas-lift operators use these meters as a diagnostic tool to find problems in the field such as choke manifold and lift valve failures. Diluent injection operators use these meters to optimize injection rates and maximize heavy oil production. The small footprint and ease of operation make it an ideal instrument for portable well testing. It provides accurate, real-time measurements of oil, water and gas flows simultaneously without separation of the phases.
