PHASE MANAGEMENT SYSTEM IN OIL AND GAS PRODUCTION SUBSEA STREAMS

The present invention presents a system that allows mixing in a controlled way the streams exported by two-phase or three-phase separators, allowing the management of the phases according to the processing needs of the SPUs. The main idea is that the outlet streams of the subsea separation modules can be routed to different SPUs in order to optimize the processing capacity of the surface plant.It is capable of manipulating in real time process parameters such as GLR (Gas-Liquid Ratio), or GOR (Gas-Oil Ratio) or Water Cut (amount of water in oil) to generate the multiphase streams required by each SPU, using the own autogenous pressure of the process to carry out this adjustment, that is, without the need for pressure raising systems or artificial lifting (pumps, compressors, gas lift, etc.) of the export streams of the system. This is possible by means of a crossflow injection control system between the phases. However, the possibility of using pressure raising systems (pumps, compressors, etc.) is not excluded, if the SPUs are at high distances, for example, and require the use of this device.
