One trip cemented expandable monobore liner system and method
View Patent ↗A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented. The cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve. The cement retainer can be milled out in a separate trip.
1. A completion method, comprising:
delivering a cementing shoe with a tubular to be expanded;
running a swage assembly through said tubular;
moving the entire cementing shoe with said advancing swage assembly;
cementing the expanded tubular through said cementing shoe.
2. The method of claim 1 , comprising:
initially delivering said shoe within said tubular to be expanded.
3. A completion method, comprising:
delivering a cementing shoe with a tubular to be expanded;
running a swage assembly through said tubular;
engaging the cementing shoe with said advancing swage assembly;
cementing the expanded tubular through said cementing shoe;
advancing said cementing shoe though said tubular as said swage assembly exits said tubular.
4. The method of claim 3 , comprising:
repositioning said cementing shoe within the tubular after said running said swage assembly.
5. The method of claim 4 , comprising:
sealing between said repositioned cementing shoe and said tubular.
6. The method of claim 5 , comprising:
actuating a seal to perform said sealing.
7. A completion method, comprising:
delivering a cementing shoe with a tubular to be expanded;
running a swage assembly through said tubular;
engaging the cementing shoe with said advancing swage assembly;
cementing the expanded tubular through said cementing shoe;
initially delivering said shoe below said tubular to be expanded and providing a selectively operated sealing device to allow said shoe to be sealed within said tubular after said tubular has been expanded.
8. A completion method, comprising:
delivering a cementing shoe with a tubular to be expanded;
running a swage assembly through said tubular;
moving the cementing shoe with said advancing swage assembly;
cementing the expanded tubular through said cementing shoe;
delivering a guide shoe with said tubular to be delivered;
engaging both said cementing shoe and said guide shoe with said swage assembly; and
cementing through both said cementing shoe and said guide shoe.
9. The method of claim 8 , comprising:
milling out both said cementing shoe and said guide shoe after said cementing.
