Software determines multiphase flow without meters
A software package devised by Loke Inc., a member of Norway`s CorrOcean Group, is routinely calculating multiphase flows from North Sea wells by monitoring only static measurements-pressures, temperatures and other available measurement quantities. A collection of three modeling programs, the software can also control the production mix and set choke values from individual wells for optimum reservoir production. Calculated flows have proven so accurate that operators now have no need for conventional flow meters or dedicated test lines. In a tuning step taken during initial well testing, Loke establishes parameters for the mathematical models in the software. Thereafter, static measurements of pressure and temperature in the producing well or manifold are converted by the software to flow. These predictions are then used to command choke valves to regulate flow. A representation of the measurement and control scheme is shown.
