Abstract
Provided is a two part milling and running tool, a well system, and a method. The two part milling and running tool, in one aspect, includes a conveyance, a smaller assembly coupled to an end of the conveyance, and a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly.
Claims24
A two part milling and running tool, comprising:
- a conveyance;
- a smaller assembly coupled to an end of the conveyance;
- and
- a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly, wherein the body lock ring include lock ring teeth configured to engage with the conveyance.
A well system, comprising:
- a main wellbore located within a subterranean formation;
- and
- a multilateral milling assembly located in the main wellbore proximate a junction between the main wellbore and where a lateral wellbore is to be formed, the multilateral milling assembly including:
- a multilateral whipstock assembly, the multilateral whipstock assembly including a whipstock body with a whipface and an opening extending therethrough;
- and
- a two part milling and running tool coupled to the multilateral whipstock assembly, the two part milling and running tool including:
- a conveyance;
- a smaller assembly coupled to an end of the conveyance;
- and
- a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly, wherein the body lock ring include lock ring teeth configured to engage with the conveyance.
A method for forming a well system, comprising:
- forming a main wellbore within a subterranean formation;
- and
- positioning a multilateral milling assembly in the main wellbore proximate a junction between the main wellbore and where a lateral wellbore is to be formed, the multilateral milling assembly including:
- a multilateral whipstock assembly, the multilateral whipstock assembly including a whipstock body with a whipface and an opening extending therethrough;
- and
- a two part milling and running tool coupled to the multilateral whipstock assembly, the two part milling and running tool including:
- a conveyance;
- a smaller assembly coupled to an end of the conveyance;
- and
- a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly, wherein the body lock ring include lock ring teeth configured to engage with the conveyance.
A two part milling and running tool, comprising:
- a conveyance;
- a smaller assembly coupled to an end of the conveyance;
- and
- a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly, further including a roughened surface located on the conveyance, the roughened surface configured to engage with the body lock ring to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly.
A well system, comprising:
- a main wellbore located within a subterranean formation;
- and
- a multilateral milling assembly located in the main wellbore proximate a junction between the main wellbore and where a lateral wellbore is to be formed, the multilateral milling assembly including:
- a multilateral whipstock assembly, the multilateral whipstock assembly including a whipstock body with a whipface and an opening extending therethrough;
- and
- a two part milling and running tool coupled to the multilateral whipstock assembly, the two part milling and running tool including:
- a conveyance;
- a smaller assembly coupled to an end of the conveyance;
- and
- a larger bit assembly slidably coupled to the conveyance, the smaller assembly and larger bit assembly configured to slidingly engage one another downhole to form a combined bit assembly, the larger bit assembly having a body lock ring in an interior thereof, the body lock ring configured to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly, further including a roughened surface located on the conveyance, the roughened surface configured to engage with the body lock ring to allow the smaller assembly to slide toward the larger bit assembly but prevent the smaller assembly from sliding away from the larger bit assembly.
