Tools and methods for use in completion of a wellbore
View Patent ↗A ported tubular is provided for use in casing a wellbore, to permit selective access to the adjacent formation during completion operations. A system and method for completing a wellbore using the ported tubular are also provided. Ports within the wellbore casing may be opened, isolated, or otherwise accessed to deliver treatment to the formation through the ports.
1. A ported tubular for installation within a wellbore to provide selective access to the adjacent formation, the ported tubular comprising:
a tubular housing comprising one or more lateral fluid flow ports, the housing adapted for installation within a wellbore;
a port closure sleeve disposed against the tubular housing and slidable with respect to the housing, the port closure sleeve shiftable between a first, upper position relative to the housing and a second, lower position relative to the housing to open and close the ports, wherein the port closure sleeve consists essentially of a tubular having a first end surface, an opposing second end surface, and a cylindrical wall extending from the first end surface to the second end surface, the cylindrical wall having a single, invariant, inside diameter; and
a location profile configured to position a shifting tool within the housing with respect to the port closure sleeve, wherein the location profile is collapsed when the sleeve is shifted to the second, lower position to open the ports.
2. The ported tubular as in claim 1 , wherein the location profile comprises a profiled surface along an innermost surface of the housing or sleeve, the profiled surface sized and spaced to mechanically engage a location device carried on a shifting tool deployed on tubing string.
3. The ported tubular as in claim 1 , wherein the inside diameter of the cylindrical wall of the port closure sleeve tubular; is not less than a minimum inside diameter of tubular segments adjacent the ported tubular segment.
4. The ported tubular as recited in claim 1 , wherein the location profile is positioned below the port closure sleeve.
5. The ported tubular as recited in claim 1 , wherein the port closure sleeve is secured to the housing in the closed position by at least one shear pin.
6. The ported tubular as recited in claim 1 , wherein the port closure sleeve is configured to shift in a downhole direction to open the fluid flow ports.
7. A ported tubular for installation within a wellbore to provide selective access to the adjacent formation, the ported tubular comprising:
a tubular housing comprising one or more lateral fluid flow ports, the housing adapted for installation within a wellbore;
a port closure sleeve disposed against the tubular housing and slidable with respect to the housing to open and close the ports, wherein the port closure sleeve consists essentially of a tubular having a first end surface, an opposing second end surface, and a cylindrical wall extending from the first end surface to the second end surface,the cylindrical wall having a single, invariant, inside diameter; and
a trap ring comprising an engageable profile along the inner surface of the tubular housing configured to engage a lock ring coupled to an adjacent surface of the sleeve, the trap ring configured to lock a slided position of the sleeve with respect to the housing.
8. The ported tubular as recited in claim 7 , wherein the lock ring cornprises a snap ring.
9. The ported tubular as recited in claim 7 , wherein the port closure sleeve is secured to the housing in the dosed position by at least one shear pin.
10. The ported tubular as recited in claim 7 wherein at least one end surface of the port closure sleeve is planar and orthogonal to the longitudinal axis; of the port closure sleeve.
11. The ported tubular as recited in claim 7 wherein at least one end surface of the port closure sleeve is beveled.
