摘要： 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.

摘要： Methods and apparatus for expanding a tubular with the aid of a compressive force are disclosed. A tubular is run into a wellbore. While the tubular is in a compressive state, the tubular is expanded into its desired form. The expanded tubular can be used for multiple downhole functions such as completing multilateral junctions in a wellbore, patching apertures in a wellbore and lining a wellbore.

摘要： A method and apparatus wherein a Genetic Algorithm or an Evolutionary Program is used as an intelligent search technique addresses the problem of assigning sensor reports in multi-target tracking with one or more sensors. The inventive technique of tracking objects includes receiving sensor reports from at least one sensor over multiple time scans; formulating hypotheses as lists of associations between the sensor reports; constructing at least one track for each of the hypotheses; scoring each of the hypotheses; searching through a portion of the hypotheses, using an intelligent search algorithm, to find a good hypothesis; and determining the state of the tracked objects.
