摘要:
Methods relate to tubulars that may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

A reciprocating exercise apparatus is provided which enables the user to exercise lower body muscle groups. The apparatus includes a frame structure means, a user support means having a seat, and a user engagement means. The back end of the user engagement means is pivotally mounted to the frame structure means. An engagement assembly is mounted to the front end of the user engagement means via an assembly support, with the assembly support capable of moving in the upward and downward directions. The lower end of the assembly support is connected by a wheel member to a guide member, which is mounted on the frame structure means. To normally operate the device, the user sits in the seat and pushes against the engagement assembly, with the general thigh portion of the leg, in either the downward, upward, and/or side directions. The wheel member will follow the contour of the guide member. Optional items may include a back support member, handle members, a resistance means, and/or a motor means.

A water vaporization apparatus is provided which uses the heat from the sun to vaporize water from a water collection means. The water collection means has a water container member which may be partially submerged in a water reservoir, or connected to a remote reservoir of water. The water container member has a water transport member connected to it, through which water from the water reservoir may move into the water container member. The water from the reservoir will move into the water container member as the sun vaporizes water from the water container member, since the water levels will naturally try and reach equilibrium. An electricity generation means may be operatively connected to the water collection means in such a manner that the movement of the water through said water transport member may be used to generate electricity. In an alternate configuration, a water condenser means may be connected to the water collection means in such a manner that the vaporized water may be transformed back into liquid form, for use as drinking water and/or industrial water. The electricity generation means and the water condenser means may also be used simultaneously by the same apparatus.

The present invention generally relates to apparatus and methods for expanding a tubular. In one embodiment, an expander tool includes a body having at least one recess therein. An expansion assembly disposable in the at least one recess includes a piston that outwardly extends from the body in response to a radially outward force. The expansion assembly includes one or more rollers disposed on a shaft such that the rollers rotate at different speeds. In order to improve a rolling ratio, the shaft is arranged on the piston at an outward angle relative to a longitudinal axis of the tool. The expansion assembly is disposed along the tool at a skew to provide tractoring and reduce slippage due to axial movement. A bearing adjacent the roller and rotationally secured to the roller reduces roller heating and wear. In another aspect, methods for expanding a tubular within a wellbore are provided.

A diagramming tool is provided that allows a diagram to be defined as a specialization of a “parent” diagram. The “child” diagram is defined based on the “parent” diagram such that the child diagram references the parent and contains only nodes and edges which represent differences between the instant diagram and its parent diagram. A diagram inherits all of the nodes and edges, and their properties, of its parent and adds, deletes, or redefines the nodes and/or edges that represent the differences or specializations.
