System and a method for control of oil and gas flow in conduits

Abstract

A system and a method are described for control of flow of oil and gas in pipelines on an installation in connection with testing of the oil and gas from a well, comprising: at least, a first test manifold () to which a number of wells are connected, a first pipeline () for flow of oil and gas from said first test manifold to sand separator equipment (), at least, a second test manifold () to which a number of wells are connected and a second pipeline () for flow of the oil and gas from said second test manifold to the sand separator equipment (). A crossflow manifold () is arranged between said first and second pipelines () and the sand separator equipment (), where the crossflow manifold () is arranged to steer oil and gas from the first pipeline () to an inlet line () of the sand separator equipment (), and to steer oil and gas from an outlet line () of the sand separator equipment () and to the second pipeline (), and also that the crossflow manifold () is arranged to steer oil and gas from the second pipeline () to the inlet line () of the sand separator equipment (), and to steer oil and gas from the outlet line () of the sand separator equipment () and to the first pipeline ().
