Abstract
A well apparatus includes a bottom hole assembly (BHA) comprising a cutting structure at one end of the BHA, a whipstock assembly for selectively deflecting the BHA to form a deviated wellbore, a whipstock connector releasably connecting the whipstock assembly to the BHA, and a whipstock support member extending between the BHA and the whipstock assembly and spaced from the whipstock connector.
Claims19
A well apparatus, comprising:
- a bottom hole assembly (BHA) comprising a cutting structure at one end of the BHA;
- a whipstock assembly for deflecting the BHA to form a deviated wellbore, the whipstock assembly comprising a whipstock support member extending between the BHA and a deflector surface of the whipstock assembly;
- and
- a whipstock connector spaced from the whipstock support member and releasably connecting the whipstock assembly to the BHA;
- and
- wherein the whipstock support member is engageable with the BHA to transfer torque from the BHA through the whipstock support member to the whipstock assembly and reduce torque transferred through the whipstock connector.

A method of forming a wellbore, the method comprising:
- releasably connecting a bottom hole assembly (BHA) to a whipstock assembly with a whipstock connector;
- supporting the BHA from the whipstock assembly with a whipstock support member of the whipstock assembly that is engaged with the BHA to transfer torque from the BHA through the whipstock support member to the whipstock assembly and reduce torque transferred through the whipstock connector, the whipstock support member spaced from the whipstock connector;
- and
- lowering the BHA and the whipstock assembly into a wellbore.
1 more element
A well apparatus operable with a bottom hole assembly (BHA) within a wellbore, the apparatus comprising:
- a whipstock assembly for deflecting the BHA to form a deviated wellbore, the whipstock assembly comprising a whipstock support member extending between the BHA and a deflector surface of the whipstock assembly;
- a whipstock connector releasably connecting the whipstock assembly to the BHA, the whipstock connector circumferentially spaced from the whipstock support member;
- and
- wherein the whipstock support member is engageable with the BHA to transfer torque from the BHA through the whipstock support member to the whipstock assembly and reduce torque transferred through the whipstock connector.
