  • Patent number: 11746629
    Abstract: A gas lift system includes tubing configured to be a conduit for production fluids having a weight, an inflow control valve, installed within the tubing, configured to control gas from the gas reservoir into the well, a gas-separator compressor turbine device installed within the tubing, a gas lift valve configured to allow flow of the gas from the annulus into the tubing, and an injection pressure operated gas lift valve configured to allow flow of the gas from the annulus into the tubing. The gas and the production fluids, from the oil reservoir, mix to lower the weight of the production fluids and flow the production fluids through the tubing to be produced at a surface location.

  • Patent number: 10184565
    Abstract: A mechanical end face seal having an induction heated seal ring is provided to be used for sealing high-viscosity thermo-sensitive fluids in pressure containing rotating equipment. The different embodiments particularly provide a sealing member fixed to the housing, the sealing element is constructed using ferromagnetic materials. An induction coil attached to a power source is installed outside the housing, said induction coil is supplied with an alternating current producing a time dependent magnetic field that induces eddy currents in the aforementioned sealing member generating heat thus affecting the operating temperatures of the sealing member and hence the interface temperature to achieve greater sealing efficiency, longer seal life and faster equipment startup.
