a lateral wellbore extending from the main wellbore; and
a downhole tool positioned proximate an intersection between the main wellbore and the lateral wellbore, the downhole tool including:
a whipstock assembly, the whipstock assembly including a whipface;
a packer assembly coupled to the whipstock assembly, the packer assembly including a packer element configured to move between a radially retracted state and a radially expanded state;
a remote open/close valve positioned to allow fluid into the whipstock assembly;
a downhole power unit coupled to the packer assembly, the downhole power unit configured to move the packer element between the radially retracted state and the radially expanded state; and
a downhole ported sub, the downhole ported sub coupled downhole of the whipstock assembly, the downhole power unit, and the packer assembly.
9 . The well system as recited in claim 8 , wherein the remote open/close valve is positioned downhole of the packer assembly.
10 . The well system as recited in claim 9 , wherein the remote open/close valve is positioned in the downhole ported sub.
11 . The well system as recited in claim 8 , further including production ports located between the whipstock assembly and the packer assembly, the production ports coupling an inside diameter of the downhole tool with an outside diameter of the downhole tool.
12 . The well system as recited in claim 8 , further including a second ported sub coupled to the downhole power unit, the second ported sub configured to hydraulically connect activation fluid to the downhole power unit.
13 . The well system as recited in claim 12 , wherein the second ported sub is configured to hydraulically connect activation fluid from an annulus of a wellbore to the downhole power unit.
14 . The well system as recited in claim 13 , wherein the downhole power unit has a pre-determined activation pressure, the downhole power unit configured to initiate a setting sequence of the packer assembly after receiving activation fluid having at least the pre-determined activation pressure from the second ported sub.
15 . A method, comprising:
positioning a downhole tool proximate an intersection between a main wellbore and where a lateral wellbore is to be located, the downhole tool including:
