摘要：
The present invention relates to a process for restarting core flow with viscous oil after a long standstill period. The process comprises initiating a flow of low viscosity fluid such as water into an inlet portion of a pipeline; gradually increasing the flow of the low viscosity fluid until a desired steady state condition is reached and initiating a flow of viscous oil into the inlet portion of the pipeline after the steady state condition has been reached.
