    摘要： Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.

    摘要： Systems and methods are provided for swellable material activation and monitoring in a subterranean well. A sensor system for use in a subterranean well includes a swellable material, and at least one sensor which is displaced to a wellbore surface in response to swelling of the swellable material. Another sensor system includes a sensor which detects swelling of a swellable material. A swellable well tool system includes a base pipe, a swellable material on an exterior of the base pipe, and eccentric weighting for inducing rotation of the swellable material about a longitudinal axis of the base pipe.

    摘要： A multi-layer deformable composite construction. In a described embodiment, a method of expanding a structure in a wellbore includes the steps of: positioning the structure in an unexpanded configuration in the wellbore, the structure including a wall made up of multiple layers; expanding the structure to an expanded configuration while permitting relative displacement between the layers; and then preventing relative displacement between the layers.
