INTEGRATED SURVEILLANCE SYSTEM FOR CYCLIC SOLVENT DOMINATED PROCESSES

摘要

Systems and methods for monitoring the composition of a produced fluidrecovered in abitumen recovery facility in real-time to predict a phase profile of theproduced fluid inreal-time are described herein. The systems include at least one flow ratesensor, densitysensor, temperature sensor and pressure sensor positioned between a bottomhole of awellbore and an end of a production stream, and one or more processorsoperativelycoupled to each of the sensors. The one or more processors, collectively, areconfiguredto determine a water-cut of the produced fluid in real-time, determine asolvent content ofhydrocarbons of the produced fluid in real-time based on the water-cut, ahydrocarbondensity correlation and a bitumen density correlation, and predict a phaseprofile of theproduced fluid in real-time based on the temperature and pressure of theproduced fluid.The systems are also configured to initiate actions for mitigating potentialflow assurancedisruptions based on the predicted phase profile of the produced fluid.
