Abstract
An assembly for formation and completion of deviated wellbores is disclosed which includes a toolguide and a casing section which can be used together or separately.
The toolguide includes a lower orienting section and an upper section having a sloping face, commonly known as the directional portion of a whipstock. The toolguide is coated with a material such as epoxy or polyurethane to provide a repairable surface and one which can be removed to facilitate removal of the toolguide from the well bore.
The lower orienting section has a latch which extends radially outwardly from the section and can be locked in the outwardly biased position. The casing section of the present invention includes a sleeve which can be moved between a first position in which access to the window opening of casing section is not affected and a second position in which the main casing is sealed from the liner section of a deviated wellbore to provide a hydraulic seal against passage of fluids from outside the casing of the wellbore into the main casing.

The lower orienting section has a latch which extends radially outwardly from the section and can be locked in the outwardly biased position. The casing section of the present invention includes a sleeve which can be moved between a first position in which access to the window opening of casing section is not affected and a second position in which the main casing is sealed from the liner section of a deviated wellbore to provide a hydraulic seal against passage of fluids from outside the casing of the wellbore into the main casing.
Claims (4)
1. A tieback positioning and placement tool comprising:
a housing having a longitudinal bore therethrough;
a shaft disposed in the housing for slidable movement through the bore, the shaft extending through the bore and exposed at each end of the housing, the shaft having a first end formed for connection to a drill pipe and an opposite end formed for supporting a tieback hanger; and a key retained by the housing and biased radially outwardly therefrom, the key having means for releasably locking the shaft in position in the housing, the means selected such it will release the shaft when the key is biased outwardly a predetermined distance from the housing.
a housing having a longitudinal bore therethrough;
a shaft disposed in the housing for slidable movement through the bore, the shaft extending through the bore and exposed at each end of the housing, the shaft having a first end formed for connection to a drill pipe and an opposite end formed for supporting a tieback hanger; and a key retained by the housing and biased radially outwardly therefrom, the key having means for releasably locking the shaft in position in the housing, the means selected such it will release the shaft when the key is biased outwardly a predetermined distance from the housing.
2. The tieback positioning and placement tool of claim 1 further comprising a poppet for releasably securing the rod at a fixed position relative to the housing.
3. The tieback positioning and placement tool of claim 2 wherein the poppet being actuatable to release the rod when the pressure surrounding the tool exceeds a predetermined level.
4. The tieback positioning and placement tool of claim 1 further comprising a collet supported on the housing including a plurality of circumferentially aligned dogs extending radially outwardly.
