Abstract

Methods of attaching a crown of a boring shoe to a casing section include attaching an adaptable shank to a crown, and machining the adaptable shank to configure an end thereof for attachment to a casing section after attaching the adaptable shank to the crown. Additional methods include welding an end of an adaptable shank to a crown to form a boring shoe, selecting the adaptable shank to have an average wall thickness greater than about five percent (5%) of a maximum diameter of the crown, and configuring an opposite end of the adaptable shank for attachment to a particular type of casing section after welding the shank to the crown. Boring shoes have an adaptable shank attached to a crown, wherein the shank comprises a generally cylindrical wall having an average wall thickness greater than about five percent (5%) of a maximum diameter of the crown.

Claims

What is claimed is:
1. A method of attaching a crown of a boring shoe to a section of casing, comprising:
attaching a first end of an adaptable shank comprising a generally cylindrical structure to the crown of the boring shoe; and
machining an opposite second end of the adaptable shank to configure the second end of the adaptable shank for attachment to the section of casing after attaching the first end of the adaptable shank to the crown.
2. The method of claim 1, further comprising forming the adaptable shank to comprise a metal alloy material exhibiting a tensile yield strength of at least about 60,000 pounds per square inch.
3. The method of claim 1 , further comprising form ing the adaptable shank to have a length between about twenty-five (25) centimeters (about ten (10) inches) and about two hundred (200) centimeters (about seventy-nine (79) inches).
4. The method of any one of claims 1 through 3, further comprising forming the adaptable shank to have an average wall thickness greater than about five percent (5%) of a maximum diameter of the crown.
5. The method of claim 4, further comprising forming the average wall thickness of the adaptable shank to be about 10% or more of the maximum diameter of the crown.
6. The method of claim 5, further comprising forming the average wall thickness of the adaptable shank to be about 12.5% or more of the maximum diameter of the crown.
7. The method of claim 6, further comprising forming the average wall thickness of the adaptable shank to be about 15% or more of the maximum diameter of the crown. 18
8. The method of any one of claims 1 through 3, wherein attaching a first end of an adaptable shank to the crown of the boring shoe comprises:
abutting a surface of the first end of the adaptable shank to a surface of the crown; and welding an interface between the surface of the crown and the abutting surface of the first end of the adaptable shank.
9. The method of any one of claims 1 through 3, wherein machining the opposite second end of the adaptable shank comprises machining threads on at least one of an interior surface and an exterior surface of the adaptable shank.
10. The method of any one of claims 1 through 3, further comprising:
attaching the first end of the adaptable shank to the crown at a first geographic location; transporting the boring shoe from the first geographic location to a second geographic location using a vehicle; and
configuring the opposite second end of the adaptable shank for attachment to the
section of casing at the second geographic location.
11. A boring shoe, comprising:
a crown configured for at least one of drilling and reaming a wellbore; and
an adaptable shank attached to the crown, the adaptable shank comprising a generally cylindrical wall having an average wall thickness greater than about five percent (5%) of a maximum diameter of the crown.
12. The boring shoe of claim 11 , wherein the crown is welded to the adaptable shank.
13. The boring shoe of claim 11 or claim 12, wherein the average wall thickness of the generally cylindrical wall is greater than about 10% of the maximum diameter of the crown. 19
14. The boring shoe of claim 13, wherein the average wall thickness of the generally cylindrical wall is greater than about 12% of the maximum diameter of the crown.
15. The boring shoe of claim 14, wherein the average wall thickness of the generally cylindrical wall is greater than about 15% of the maximum diameter of the crown.
16. The boring shoe of claim 15, wherein the adaptable shank comprises a metal alloy material exhibiting a tensile yield strength of at least about 60,000 pounds per square inch.
17. The boring shoe of claim 11 or claim 12, wherein the adaptable shank comprises a metal alloy material exhibiting a tensile yield strength of at least about 60,000 pounds per square inch.
