Expandable reamer assemblies include an expandable reamer module and an activation module. An outer tubular body of the activation module is rigidly coupled to a tubular body of the expandable reamer module, and an activation member of the activation module is coupled to a sleeve of the expandable reamer module, the sleeve is coupled to at least one blade and configured to move the at least one blade into an extended position. The sleeve moves axially responsive to axial movement of the activation member. Bottom-hole assemblies include an expandable reamer module and an activation module. The activation module is coupled to the expandable reamer module and configured to provide a motive force to the sleeve to move the sleeve opposite a direction of flow of drilling fluid. Methods of using expandable reamer modules include pairing two substantially identical expandable reamer modules and two respective different activation modules.

1. An expandable reamer assembly for reaming a subterranean borehole, the expandable reamer assembly comprising: an expandable reamer module comprising: a tubular body having a longitudinal axis and an inner bore;at least one blade coupled to the tubular body and configured to move between a retracted position and an extended position; anda sleeve disposed within the inner bore of the tubular both and coupled to the at least one blade, the sleeve configured to axially move relative to the tubular body to move the at least one blade into the extended position;an activation module comprising: an outer tubular body rigidly coupled to the tubular body of the expandable reamer module, the outer tubular body of the activation module having an inner bore; andan activation member at least partially disposed within the inner bore of the outer tubular body of the activation module, a longitudinal end of the activation member coupled to the sleeve to axially move the sleeve relative to the tubular body of the expandable reamer module responsive to axial movement of the activation member and to axially move the sleeve toward the activation modules; andwherein the expandable reamer module is a slave unit configured to not be activated without the activation module. 2. The expandable reamer assembly of claim 1, wherein the at least one blade of the expandable reamer module includes at least one cutting element configured to remove material from a subterranean formation during reaming. 3. The expandable reamer assembly of claim 1, wherein the expandable reamer module lacks a spring for biasing the sleeve to an axial position. 4. The expandable reamer assembly of claim 1, the expandable reamer module further comprising a yoke coupled to the sleeve, the yoke positioned to force the at least one blade into the extended position upon axial movement of the sleeve toward the activation module. 5. The expandable reamer assembly of claim 4, wherein the yoke comprises a surface proximate the at least one blade, the surface extending in a plane at least substantially perpendicular to the longitudinal axis of the body. 6. The expandable reamer assembly of claim 1, wherein the sleeve comprises one or more holes extending through a sidewall thereof. 7. The expandable reamer assembly of claim 6, further comprising at least one seal surrounding the sleeve and positioned proximate the one or more holes extending through the sidewall of the sleeve, the at least one seal configured to inhibit drilling fluid from flowing through the one or more holes when the sleeve is in a first, deactivated position and to allow the drilling fluid to flow through the one or more holes when the sleeve is in a second, activated position. 8. The expandable reamer assembly of claim 1, wherein an outer surface of the sleeve comprises one or more materials selected from the group consisting of carbide material, a tungsten carbide material, a nitride material, a chrome material, a nickel plating material, and a cobalt-chromium alloy material. 9. A bottom-hole assembly, comprising: an expandable reamer module comprising a first tubular body, at least one reamer blade movably coupled to the first tubular body, and a sleeve axially movable within the first tubular body, the sleeve coupled to the at least one reamer blade and configured to move the at least one reamer blade into an expanded position;an activation module comprising a second tubular body rigidly coupled to the first tubular body of the expandable reamer module and an activation member coupled to the sleeve, the activation member configured to provide a motive force to the sleeve to move the sleeve toward the activation module and opposite a direction of flow of drilling fluid through the bottom-hole assembly during use of the bottom-hole assembly resulting in movement of the at least one reamer blade into the expanded position; andwherein the expandable reamer module is a slave unit configured to not be activated without the activation module. 10. The bottom-hole assembly of claim 9, wherein the activation module further comprises a spring positioned to bias the activation member to a deactivated axial position. 11. The bottom-hole assembly of claim 9, further comprising a joint structure positioned between the activation member and the sleeve. 12. The bottom-hole assembly of claim 11, wherein the activation member is attached to a first longitudinal end of the joint structure and the sleeve is attached to a second longitudinal end of the joint structure. 13. The bottom-hole assembly of claim 11, further comprising at least one spacer positioned to at least partially define a distance between a longitudinal end of the activation member and a longitudinal end of the sleeve. 14. The bottom-hole assembly of claim 9, wherein the activation module comprises an electronic and hydraulic component configured to receive a signal and respond to the signal by causing hydraulic fluid to move the activation member between a deactivated axial position to an activated axial position. 15. A method of using expandable reamer modules, the method comprising: providing a first expandable reamer module comprising a tubular body and an axially movable sleeve at least partially within the tubular body;providing a first activation module comprising a tubular body configured to be coupled to the tubular body of the first expandable reamer module and an axially movable activation member configured to be coupled to the sleeve of the first expandable reamer module such that axial movement of the activation member results in axial movement of the sleeve toward the first activation module, the first activation module configured to be activated with a first activation means;pairing the first expandable reamer module and the first activation module for use in a reaming process in which the first activation module activates the first expandable reamer module to ream a subterranean formation, wherein the first expandable reamer module is a slave unit configured not to be activated without the first activation module;providing a second expandable reamer module comprising a tubular body and an axially movable sleeve, at least partially within the tubular body, the second expandable reamer module substantially identical to the first expandable reamer module;providing a second activation module comprising a tubular body configured to be coupled to the tubular body of the second expandable reamer module and an axially movable activation member configured to be coupled to the sleeve of the second expandable reamer module such that axial movement of the activation member results in axial movement of the sleeve toward the second activation module, the second activation module configured to be activated with a second, different activation means; andpairing the second expandable reamer module and the second activation module for use in a reaming process in which the second activation module activates the second expandable reamer module to ream a subterranean formation. 16. The method of claim 15, further comprising: providing a third activation module comprising a tubular body configured to be coupled to the tubular body of the first expandable reamer module and an axially movable activation member configured to be coupled to the sleeve of the first expandable reamer module such that axial movement of the activation member results in axial movement of the sleeve, the third activation module configured to be activated with a third activation means different from the first activation means; andpairing the first expandable reamer module and the third activation module for use in a reaming process in which the third activation module activates the first expandable reamer module to ream a subterranean formation. 17. The method of claim 15, wherein providing a first expandable reamer module comprises providing a first expandable reamer module lacking an internal spring for biasing the sleeve to any axial position. 18.
