Abstract: A sliding sleeve (100) opens with a deployed ball (B). The sleeve has a seat (170) disposed in a bore of the inner sleeve and comprises a landing ring (172) disposed in the bore and being movable axially from a first axial position to a second axial position therein. A compressible ring (174) is also disposed in the bore and defines a space between a portion of the compressible ring and the bore. The landing ring in the first position supports the deployed ball with a first contact dimension and moves the inner sleeve to the opened position in response to application of first fluid pressure against the engaged ball. The landing ring moves from the first position to the second position in the inner sleeve when in the opened position in response to second fluid pressure applied against the engaged ball. The landing ring in the second position fits in the space between the compressible ring and the second bore and contracts the compressible ring inward. As a result, the segments moved inward support the engaged ball with a second contact dimension narrower than the first contact dimension.

Abstract: A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port.
Abstract translation: 一个滑动套筒打开一个部署的球。 套筒具有设置在壳体中的座位，并且座椅具有用C形环或其它偏置元件彼此向外偏压的段。 最初，座椅在滑动套筒中具有膨胀状态，使得座部分段向外扩张抵靠壳体的孔。 当适当尺寸的球部件被部署在井下时，球接合扩展的座椅。 对着座球施加的流体压力将座椅移动到内套筒的孔中。 当这种情况发生时，座椅收缩，这增加了座椅与球的接合面积。 最后，座椅到达内套筒中的肩部，使得施加在就座球上的压力现在使内套筒移动到壳体中以打开滑套的流动口。

Abstract: An expandable liner is used to re-complete a wellbore for a re-fracturing operation. The expandable liner may be used to cover the old perforations and provide a larger bore after expansion. The larger bore allows the new completion perforations and fracturing operation to be more easily achieved. In one embodiment, the expandable liner may have a rib disposed around an outer diameter of the expandable tubular, wherein the rib is configured to form a seal with the outer tubular.
