  • REAL-TIME MONITORING OF HYDROCARBON PRODUCTIONS
    Publication number: 20190203581
    Abstract: A method includes obtaining a sample of a fluid from a subterranean zone while the fluid is being extracted from the zone. A chemical composition of the sample is measured. A temperature and a pressure of the subterranean zone are measured. The measured properties are associated with a time point. The measured properties are incorporated into a set of historical data. A chemical composition of a fluid to be extracted from the subterranean zone at a future time point is determined based on the set of historical data. A presence of a liquid phase in the fluid to be extracted from the subterranean zone at the future time point is determined. A flow rate of the fluid being extracted from the subterranean zone is adjusted in response to determining the presence of the liquid phase in the fluid to be extracted from the subterranean zone at the future time point.

  • Electrical submersible pumping system with separator
    Patent number: 10337312
    Abstract: A system and method of producing fluid from a wellbore, and that separates water from the fluid. The system includes an electrical submersible pumping system with a pump having impellers and diffusers, and a separation system at a discharge end of the pump. The separation system includes a helical flow path and separation chamber downstream of the path. Directing the fluid through the helical flow path centrifugally separates the water from the fluid. Thus when the fluid flows into the separation chamber from the helical flow path, the water migrates to the outer radius of the separation chamber. The separated water flows through ports on the outer sidewall of the separation chamber, and the lower density portion of the fluid flows through a port proximate a middle portion of the separation chamber.
