Whipstock/bottom hole assembly interconnection and method
View Patent ↗A whipstock interconnection body including a whipstock interface, a bottom hole assembly (BHA) interface, the BHA interface including a feature configured to inherently grip the BHA. A whipstock interconnection body including a whipstock interface, a bottom hole assembly (BHA) interface, the BHA interface configured for attachment to a back surface of the whipstock. A whipstock/BHA assembly including a whipstock, a BHA, a whipstock interconnection body releasably securing the whipstock to the BHA, the whipstock interconnection body including a whipstock interface, a bottom hole assembly (BHA) interface, the BHA interface including a feature configured to inherently grip the BHA. A whipstock/BHA assembly including a whipstock, a BHA, a whipstock interconnection body releasably securing the whipstock to the BHA, the whipstock interconnection body including a whipstock interface, a bottom hole assembly (BHA) interface, the BHA interface configured for attachment to a back surface of the whipstock.
1. A whipstock/BHA assembly comprising:
a whipstock;
a BHA;
a tubular whipstock interconnection body releasably securing the whipstock to the BHA, the tubular whipstock interconnection body including a plurality of cantilevered resilient fingers nested with a plurality of flutes of the BHA such that only the plurality of cantilevered fingers themselves hold onto the flutes thereby solely axially securing the tubular whipstock interconnection body to the BHA.
2. The assembly as claimed in claim 1 wherein the tubular whipstock interconnection body further includes a whipstock interface.
3. The assembly as claimed in claim 1 wherein at least one finger of the plurality of fingers includes a projection.
4. The assembly as claimed in claim 1 wherein the at least one finger of the plurality of fingers engages a fluid port of the BHA.
5. The assembly as claimed in claim 1 wherein the at least one finger of the plurality of fingers is resilient.
6. The assembly as claimed in claim 1 wherein the plurality of fingers wrap more than 50% around the BHA.
7. The assembly as claimed in claim 1 wherein the tubular whipstock interconnection body is attached to a face of the whipstock.
8. The assembly as claimed in claim 1 wherein the tubular whipstock interconnection body is attached to a back side of the whipstock.
9. The assembly as claimed in claim 1 wherein the tubular whipstock interconnection body comprises a composite material.
10. The assembly as claimed in claim 1 wherein the tubular whipstock interconnection body comprises a selectively degradable material.
