Handling scale in oil production facilities. Oilfield scale mainly comprises inorganic salts, the most common being calcium carbonates and barium and strontium sulphates.
Multiphase flow simulators are currently based on one-dimensional, ‘mechanistic’ flow models.
Multiphase flow may be obstructed by physical phenomena such as liquid slugs or surges, or by physical-chemical phenomena.
An active slug control system on the Heidrun field in the Norwegian Sea has produced a more stable wellstream flow into the first stage separator.
