Multiphase and wet gas metering provide a low-capex solution ///

The benefits of metering the contribution from each well in a field may, in general, be quantified by how efficiently the production system is utilized at any point in time, and ultimately by the overall field recovery factor. Recent studies by Statoil, Hydro and the Norwegian Petroleum Directorate (NPD) show a 15% to 20% difference in recovery factor from subsea to platform wells. Multiphase and wet gas metering play an important role in closing this gap. More and more offshore field developments, particularly in deep water, are opting for a solution, where a large number of wells are tied back to a limited number of flowlines, since this will provide the lowest capex solution. To add to the complexity, artificial lift may be provided through a limited number of gas lift lines, or by a limited number of booster or multiphase pumps. All these elements contribute to increasing the number of variables to be optimized simultaneously...
