摘要:
The present invention provides a liner hanger and a method of hanging a liner in a wellbore. In one aspect, a process for setting a liner in a wellbore is provided in which a tubular having a slip formed on an outer diameter of the tubular at a first location and a preformed bypass for circulating a fluid disposed at a second location is set and expanded into substantial contact with an inner diameter of the wellbore, a casing, or another liner. In another aspect, a process for setting a liner in a wellbore is provided in which a tubular having a slip formed on an outer diameter of the tubular at a first location is placed in the wellbore, a bypass for circulating a fluid is formed downhole, the liner is set and expanded into substantial contact with an inner diameter of the wellbore, a casing, or another liner. In yet another aspect, a process for creating a liner top seal is provided in which the liner is set by expanding a protrusion in an upper end of a tubular into substantial contact with an inner diameter of the wellbore, and the upper end of the tubular is then reformed and expanded into substantial contact with the inner diameter of the wellbore.
