Abstract
An apparatus comprises a guidance sub to be attached to a tubular string for conveyance of the tubular string in a multilateral wellbore. The guidance sub comprises an articulating buoyancy structure that comprises multiple buoyancy links comprised of a buoyant material such that the articulating buoyancy structure is to have a buoyancy within a well fluid that is downhole in a primary wellbore, wherein the multiple buoyancy links are coupled together such that joints are formed between the multiple buoyancy links to allow movement between adjacent buoyancy links of the multiple buoyancy links, wherein the articulating buoyance structure is configured to direct guidance sub out of a multilateral window from a main bore and into a lateral bore of the multilateral wellbore.
