Abstract

A drilling assembly supports a liner (34) for making a wellbore . The BHA (10) comprises a pilot bit (12) and a reamer (22) above it that is larger in diameter than the suspended liner. If the BHA (10) needs to be pulled out, the reamer (22) is brought into contact with the liner (34) and a latch mechanism (30) between the two engages as another latch (28) that had held the reamer (22) bit to the BHA (10) is released. The reamer bit (22) stays with the liner as the BHA (10) is pulled and later reinserted. On the way in the BHA (10) latches to the reamer bit (22) which then unlatches from the liner bottom (32) . Preferably, splines (24) and a shoulder (26) on the BHA (10) are used to drive the reamer bit as opposed to any power being transmitted through the latch between the BHA and the reamer bit. However, the latch mechanism between the BHA and the reamer bit could also provide torque and weight on bit for drilling operations. The process may be repeated.

Claims (19)

1. A drilling assembly in advance of a tubular in a wellbore, comprising:
a tubular in the wellbore;
a bottom hole assembly comprising a bit and a reamer extending through said tubular;

said reamer selectively connectable to either said assembly for support of the weight of said reamer or to said tubular for removal of said bit through said tubular.
2. The assembly of claim 1, wherein:
said reamer is selectively releasable to drop from said bottom hole assembly.
3. The assembly of claim 2, wherein:
said reamer can be reconnected to said bottom hole assembly after being selectively released.
4. The assembly of claim 1, wherein:
said reamer is selectively latchable at a given time to said bottom hole assembly or said tubular.
5. The assembly of claim 4, wherein:
said bottom hole assembly further comprises a rotational drive for said reamer separately located from the location where said bottom hole assembly puts weight on said reamer.
6. The assembly of claim 4, wherein:
said bit is removable through said reamer and said tubular when said reamer is selectively supported by said tubular.
7. The assembly of claim 4, wherein:
said reamer when latched to said bottom hole assembly further comprises a lost motion feature allowing some relative movement therebetween.
8. The assembly of claim 5, wherein:
said reamer when latched to said bottom hole assembly further comprises a lost motion feature allowing some relative movement therebetween;
said lost motion allows said bottom hole assembly to move relatively to said reamer to allow the location that puts weight on said reamer to come in contact with it while said rotational drive remains engaged.
9. The assembly of claim 8, wherein:
said rotational drive comprises mating splines.
10. A drilling assembly in advance of a tubular in a wellbore, comprising:
a tubular in the wellbore;
a bottom hole assembly comprising a bit and a reamer, extending beyond said tubular;

said reamer selectively connectable to said tubular for support of the weight of said reamer.
11. The assembly of claim 10, wherein:
said bottom hole assembly comprises a drive that selectively engages said reamer while releasing said reamer from support by said tubular.
12. The assembly of claim 11, wherein:
said drive comprises splines.
13. The assembly of claim 10, wherein:
said bit is removable through said reamer and said tubular when said reamer is connected to said tubular.
14. The assembly of claim 11, wherein:
said bottom hole assembly puts weight on said reamer at a separate location from said drive.
15. The assembly of claim 10, wherein:
said bottom hole assembly retains said reamer away from said bit when said reamer is not supported by said tubular.
16. The assembly of claim 10, wherein:
said assembly supports said tubular for tandem movement with said bit while said bit is advancing.
17. The assembly of claim 10, wherein:
said bit moves with respect to said tubular.
18. The assembly of claim 1, wherein:

said assembly supports said tubular for tandem movement with said bit while said bit is advancing.
19. The assembly of claim 1, wherein:
said bit moves with respect to said tubular.
