Oil production from formerly producing wells may be restored without removing a preexisting production tube by perforating the production tube above the tubing packer and charging the casing annulus at the surface with a pressurized charging fluid fluid, preferably deoxygenated air, that is lighter than water. The pressurized charging of the casing annulus with charging fluid is continued to purge the production tube flow bore of a static water column and reduce the tubing column head pressure against the formation production zone.

A method of producing a print on a recording medium includes receiving negative image data for the print to be produced. A selected region of the recording medium is discharged. Charged fluid is deposited in a selected charged-fluid pattern corresponding to the negative image data on the selected region of the recording medium. Charged dry ink having charge of the same sign as the charge in the deposited charged-fluid pattern is deposited onto the recording medium. The deposited dry ink is repelled by the charged-fluid pattern and adheres to the recording medium outside the charged-fluid pattern.

A closed hydrostatic circuit with variable charge and variable flushing systems is disclosed. A variable displacement charge pump is configured to supply charge fluid and pilot control fluid to the hydrostatic circuit. An electronically controlled pressure regulating valve is in communication with an output of the charge pump and is linked to a controller. When the hydrostatic control system detects a high hydraulic temperature condition, the electronically controlled pressure regulating valve, that is in communication with an output of the charge pump and that is linked to a controller, increases the charge pump flow. A bidirectional variable displacement hydrostatic motor is connected in parallel to two input/output lines. A flush valve is in communication with the hydrostatic motor and both input/output lines. The flush valve and hydrostatic motor are both in communication with the flush orifice and a flush relief valve. When the pressure regulating valve causes the charge pump to operate at or near a full capacity, fluid exits the flush valve and passes through both the flush orifice and the flush relief valve. In contrast, when the pressure regulating valve causes the charge pump to operate at a lower or near minimum capacity, fluid exits the flush valve and passes through the flush orifice only without passing through the flush relief valve.

An apparatus having a wall configured to serve as at least part of a chamber for containing a charge fluid is provided. The wall includes a heat exchanger portion integrally formed with the wall.

The heat exchange portion is configured to contribute strength to the wall so as to provide containment of the charge fluid.

A continuous inkjet recording apparatus forms a continuous stream of droplets from a jetted fluid. A charge electrode is employed to characterize droplets selected for printing from droplets that are not selected for printing. The charge electrode is sized and optionally positioned such that a specific droplet scheme can be employed to minimize droplet trajectory variations from droplet-to-droplet electrostatic field effects. Additionally, the charging surface is sized and positioned to minimize droplet trajectory variations that arise from charge electrode-to-droplet electrostatic field effects. By minimizing both these sources of droplet trajectory variation, the final print quality of the continuous inkjet apparatus is improved.
