摘要： An expansion and cementing assembly is run into the well as the expandable liner is made up. A work string is tagged into the expansion assembly and run to depth. Pressure drives the swage to initially expand and move uphole with the attached work string until the liner is expanded above the location of the subsequent cement placement. The assembly is then lowered to engage the guide/float shoe to perform the cementing step. The swage assembly is then released from the guide/float shoe and the balance of the expansion is performed without further expansion against the recently placed cement. The expansion assembly can start at the guide/float shoe or higher, in which case expansion can occur initially in a downhole direction and later be completed in an uphole direction. Variations without cementing are also contemplated.

摘要： An expansion assembly is run into the well as the expandable liner is made up. A work string is tagged into the expansion assembly and run to depth. Pressure drives the swage to initially expand and move uphole with the attached work string until the liner is expanded to set at least one external packer. The balance of the expansion in the uphole direction is continued until the string is expanded into sealing support of a higher string in the wellbore and the variable swage comes out of the hole with the work string. A shoe is milled out and the process can be repeated.

摘要： A well having a minimum drift between or among strings is provided using strings that have a recessed segment and a hanging segment. The length of the recessed segment in the lower end of the upper string is substantially longer than the hanging segment of the lower string that is passed through it. The hanging segments define the drift dimension. In the event the lower string gets stuck in the open hole before it is fully advanced, the hanging segment of the lower string may still be in the recess of the upper string so that the drift dimension can be preserved. Preferably the recess segment is the substantial length of the tubular string apart from its hanging segment near its top end. One or more laterals can be extended through the recessed segments while retaining the drift dimension.
摘要翻译： 使用具有凹陷段和悬挂段的串来提供具有串之间或之间的最小漂移的阱。 上部的下部的凹部的长度比通过下部的弦的悬挂段长得多。 悬挂段定义漂移尺寸。 如果在完全前进的情况下，下方的绳子被卡在开孔中，则下部绳索的悬挂部分仍然可能位于上部绳索的凹槽中，从而可以保持漂移尺寸。 优选地，所述凹部段是所述管状串的远离其顶端附近的悬挂段的实质长度。 一个或多个侧面可以延伸穿过凹陷段，同时保持漂移维度。

摘要： A location and orientation assembly suitable for use in a multi-lateral wellbore may include a coupling portion, an upper muleshoe, a muleshoe spacer and a bottom muleshoe. The bottom muleshoe may connect to the coupling portion through a threaded connection. A method for locating and orienting in a multi-lateral wellbore includes providing a locating and orientation assembly. In the orientation assembly a coupling portion is provided and an upper muleshoe is inserted into the coupling portion. A muleshoe spacer is inserted into the coupling portion so as to matingly contact the upper muleshoe portion. Part of a bottom muleshoe is inserted into the coupling portion so as to matingly contact the muleshoe spacer. The coupling portion is jointed to the bottom muleshoe by a threaded connection.
