摘要： A method for removing a viscous hydrocarbonaceous fluid or oil from a formation where carbon dioxide is utilized. Gaseous carbon dioxide is injected, by a pre-set time interval or a computer actuated valve means, into a well near a productive interval. Injection continues for a time sufficient for the carbon dioxide and oil to mix thereby decreasing the oil's viscosity and facilitating gas lift of an oil of reduced viscosity to the surface.

摘要： Systems and methods for the production of hydrocarbons from a wellbore. One or more combination tools can be disposed along a casing string inserted into a wellbore. Each combination tool can contain a body having a bore formed therethrough; a sliding sleeve at least partially disposed in the body; one or more openings disposed about the body at a first end thereof; and a valve assembly and a valve seat assembly at least partially disposed within the bore at a second end thereof. While initially permitting free bi-directional flow of fluids within the casing string, the sliding sleeve within each combination tool can be manipulated to close the valve within the tool, thus permitting pressure testing of the casing string. The sliding sleeve can be further manipulated to open the one or more openings thereby permitting hydraulic fracturing and production of a hydrocarbon zone surrounding the combination tool.

摘要翻译： 从井筒生产碳氢化合物的系统和方法。 一个或多个组合工具可以沿着插入井筒的套管柱布置。 每个组合工具可以包含具有穿过其中形成的孔的主体; 至少部分地布置在所述主体中的滑动套筒; 一个或多个在其第一端处围绕身体设置的开口; 以及在其第二端处至少部分地设置在所述孔内的阀组件和阀座组件。 虽然最初允许流体在套管柱内的自由双向流动，但是可以操纵每个组合工具内的滑动套筒以关闭工具内的阀，从而允许套管柱的压力测试。 可以进一步操纵滑动套筒以打开一个或多个开口，从而允许水力压裂和围绕组合工具的烃区域的产生。

摘要： A water pressure system includes a pressure tank installed underground within the well casing of a well. The water pressure system includes a submersible pump connected to the inlet of the pressure tank by a drop pipe. The outlet of the pressure tank is connected to a second drop pipe and in turn to a discharge pipe for distribution of pressurized water to a house or other building. A pressure switch is connected to the pressure tank for controlling the submersible pump. The pressure tank includes an outer sidewall with an inlet end and an outlet end. A flexible diaphragm bladder located within the outer sidewall is connected between the inlet and outlet of the tank. In a first embodiment, a tube extends through the center of the bladder between an inlet opening and an outlet opening. The tube has a plurality of holes therein to allow water to flow into and out of the flexible bladder. Pressurized air fills the space between the bladder and the outer sidewall to pressurize the water in the bladder. The pressure tank may be used in combination with a flow control valve, a relief valve, a flow control valve incorporating a relief valve, a standard submersible pump, and/or a variable speed submersible pump to provide and maintain a constant flow of water at a constant pressure through the system.
