Abstract: The present invention provides a method of producing an oil, water, and gas well using a gas carrier/transport system to remove produced liquids and contained solids by altering the flow regime of the production fluids towards or into a flow regime in which gas is the continuous fluid. This can be accomplished by use of supplemental gas flow (hydrocarbon or non-hydrocarbon) and/or stimulation of the production sand or coal bed gas flow with a reduced pressure drop across the well once near or in a gas-continuous flow regime. This invention can be applied to any well with insufficient formation gas pressure to prevent liquid buildup within the well during production. The present invention utilizes a second production pipe (or the annulus between the casing and the pipe), sized to transport compressed gas from the wellhead area down into the production liquid and into the production pipe. This flow of gas will cause the well fluids to flow up the pipe by approaching or entering a gas-continuous flow regime.

Abstract: Cord guide, such as a pulley, and support therefor, for use with a liftable shade, as a Roman shade or a venetian blind. There is provided a pivotally suspended cord guide support for use with a liftable shade which will suspend the cord guide in a pivotal manner so that the pull cords may be held for operation at a substantial angle with respect to the wall without diminishing their effectiveness in operating the shade. Specifically, the cord guide is supported within a generally conventional clevislike structure which has a specially constructed head end adapted for pivotal support on and by a ceiling or wall attachable bracket. With such pivotal support, the clevis and the cord guide carried thereby, while normally hanging parallel with the wall, can be angled away therefrom to permit greater ease in pulling of the shade cords but without diminishing the accuracy or effectiveness of said cords in the operating of the shade. A lock and guides for the shade cords may also be provided if desired.
