  • Patent number: 12116874
    Abstract: A method for neutralizing hydrogen sulfide in a well using oxidants by installing a venturi jet pump between a packer and a tubing string in a reservoir, injecting oxidant into water forming a power fluid using a surface tension modification generator; continuously injecting the power fluid into tubing in the source well or oil field production well at 50 psi-5000 psi to an inlet nozzle of the venturi jet pump. Velocity increases and pressure decreases on the power fluid as fluid flows through the inlet nozzle. Simultaneously drawing in reservoir fluid and mixing with the power fluid in a draw down chamber forming a molecularly mixed fluid. Mixing oxidant with reservoir fluid for 0.1 to 10 seconds to scavenge hydrogen sulfide, methyl sulfide and/or explode cell membranes of anaerobic bacteria of the reservoir and discharging the treated stream from the venturi jet pump up an annulus of the wellbore to surface.

  • Patent number: 8622140
    Abstract: A method to produce formation fluid from an oil or gas well. The methods employs a jet pump and a spoolable multi-string tubing system. The jet pump is adapted to produce formation fluid, which may be produced in combination with power fluid. The multi-string tubing system consists of two or more tubing conduits, allowing surface pump equipment to deliver power fluid to the jet pump down a supply tubing string, while return fluid is returned up a return tubing string. Other downhole functions can be provided with the inclusion of additional features on the jet pump and additional conduits or conductors in the multi-string tubing system. Preferred embodiments provide additional functionality by inclusion of a jetting sub, sensing elements, or a back-pressure valve to the jet pump, and auxiliary tubing strings or communication members to the spoolable multi-string tubing system.
