Abstract: Provided is a two-part drilling and running tool, a well system, and a method for forming a well system. The two-part drilling 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 two-part drilling and running tool, according to this aspect, further includes a one way mechanism coupled between the smaller assembly and the larger bit assembly, the one way mechanism configured to allow the smaller assembly and larger bit assembly to axially slide in one direction relative to one another and prevent the smaller assembly and larger bit assembly from axially sliding in an opposite direction relative to one another.

Abstract: Provided is a downhole tool, and a method for forming a well system. The downhole tool, in one aspect, includes a whipstock assembly, a packer assembly removably coupled to the to the whipstock assembly, and an anchor assembly coupled to the packer assembly. The downhole tool, according to this aspect, further includes a completion assembly coupled to the anchor assembly, the whipstock assembly, packer assembly, anchor assembly and the completion assembly configured to be run-in-hole in a single trip.

Abstract: Provided is a downhole tool, a well system, and a method for forming a well system. The downhole tool, in one aspect, includes a latch collet including a collet body, the collet body having a collet body slot on a radial interior surface thereof and a plurality of collet fingers, as well as a mandrel positioned within the collet body, the mandrel having a mandrel opening extending through a thickness (tm) thereof, and a running tool collet located within the mandrel, the running tool collet having a running tool collet slot on a radial exterior surface thereof. The downhole tool, according to this aspect, further includes a locking dog positioned within the mandrel opening.

Abstract: Provided is a latch collet, a well system, and a method for forming a well system. The latch collet, in one aspect, includes a collet body, the collet body having a plurality of collet fingers. The latch collet, according to this aspect, further includes a collet prop button located on a radial interior of each of the plurality of collet fingers, the collet prop button configured to engage with a profile of a mandrel for running the latch collet downhole, and configured to be propped radially outward by the mandrel to cause torque buttons located on a radial exterior of each of the plurality of fingers to remain engaged with associated alignment profiles in a latch coupling when positioned at an acceptable position downhole.

Abstract: Provided is a downhole tool, and a method for forming a well system. The downhole tool, in one aspect, includes a whipstock assembly, a packer assembly fixedly coupled to the to the whipstock assembly, and an anchor assembly coupled to the packer assembly. The downhole tool, according to this aspect, further includes a completion assembly coupled to the anchor assembly, the whipstock assembly, packer assembly, anchor assembly and the completion assembly configured to be run-in-hole in a single trip.

Abstract: Provided is a downhole tool, a well system, and a method for forming a well system. The downhole tool, in one aspect, includes a latch collet including a collet body, the collet body having a collet body opening extending through a thickness (tcb) thereof and a plurality of collet fingers, as well as a mandrel positioned within the collet body, the mandrel having a mandrel slot therein. The downhole tool, according to this aspect, further includes a bore sensor positioned within the collet body opening and the mandrel slot, the bore sensor configured remain in a radially extended state when the latch collet is in too large size casing and configured to be pushed to a radially compressed state when the latch collet is in the correct size casing and thereby not prevent the collet body and the mandrel from sliding relative to one another.

Abstract: Provided is a latch collet, a well system, and a method for forming a well system. The latch collet, in one aspect, includes a collet body, the collet body having a plurality of collet fingers. The latch collet, according to this aspect, further includes a torque button located on a radial exterior of each of the plurality of collet fingers, wherein a width (WTB) of each of the torque buttons is within 10% of each other.

Abstract: Provided is a downhole tool, a well system, and a method for forming a well system. The downhole tool, in one aspect, includes a latch collet including a collet body, the collet body having a plurality of collet fingers, and a mandrel positioned within the collet body. The downhole tool, according to this aspect, further includes a packer assembly positioned axially between the collet body and the mandrel, the packer assembly configured to move from a radially retracted state when the mandrel and collet body are being run-in-hole to a radially extended state when the collet body has engaged with a latching profile and weight is placed down upon the packer assembly.

Abstract: Provided is a latch coupling, a well system, and a method for forming a well system. The latch coupling, in one aspect, includes a housing having an outside diameter (OD) and an inside diameter (ID). The latch coupling, according to this aspect, further includes a plurality of axial alignment slots located along the inside diameter (ID) of the housing, wherein a width (WAS) of each of the plurality of axial alignment slots is within 10% of each other.

Abstract: Provided is a downhole tool, a well system, and a method for forming a well system. The downhole tool, in one aspect, includes a whipstock assembly, and a completion assembly. The downhole tool, according to this aspect, further includes a fluid loss device positioned between the whipstock assembly and the completion assembly.
