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.

Method for neutralizing hydrogen sulfide in a wellbore with a venturi jet pump and oxidants

A method for evaluating the potential effectiveness of refracking a previously fracked oil/gas well is accomplished by isolating a plurality of previously fracked zones of an oil/gas well in a formation and measuring the fluid flow rates from the isolated zones using a three phase flow meter positioned within the well at or near the previously fracked zones. The zones may be isolated by an isolation assembly which includes two packers connected by a perforated pipe and attached to a tubular positioned within the well.

The zones may be isolated by an isolation assembly which includes two packers connected by a perforated pipe and attached to a tubular positioned within the well.

A jet pump assembly is adapted to be releasably attached to a tubular member of a tubular string in an oil well. The jet pump may be pumped out of the tubular string to the surface by a reverse flow of power fluid down the well between the tubular string and the casing of the well. Consequently the jet pump may be serviced or reconfigured to a direct pumping mode without the necessity of a wire line or other apparatus. A sensor for measuring downhole parameters such as temperature and pressure etc. is positioned within a cavity located in a lower portion of the jet pump so as to be removable from the well with the pump.

Flow back jet pump

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.
