Оil-gas-condensate fields. The systematic approach to control multiphase stream

Abstract

   One of characteristic features of oil-gas-condensate fields is the flow of a highly gaseous multi-phase fluid in wells and gathering system pipelines. Due to the high gas content, the fluid flow is unstable with pockets forming in the pipelines. This causes problems in operation of the fluid production, gathering and treatment systems which requires a special approach to engineering of the oil-gas-condensate field infrastructure. Based on performed research and selected engineering criteria, it is considered reasonable from both technical and economic standpoint to make the choice of a gas/liquid transportation method (combined or separate) when the field production system is being designed. A systematic approach to controlling multiphase flows allows the field operator to determine the required fluid flow parameters and develop measures to ensure flow stability and, accordingly, set up a safe and efficient fluid production and transportation process
