Summary:An expandable float shoe and associated methods are provided. In a described embodiment, an expandable float shoe is attached to a leg of an expandable wellbore junction. The float shoe and leg are radially compressed, such as by folding along their axial lengths. The wellbore junction is conveyed into a well and expanded by applying pressure therein. The float shoe expands outward, along with the leg of the wellbore junction. Un sabot flottant expansible et des méthodes connexes sont ici présentés. Dans un spécimen décrit, un sabot flottant expansible est attaché au montant d'un raccord de puits de forage expansible. Le sabot flottant et le montant sont radialement comprimés, comme par pliage le long de leurs longueurs axiales. Le raccord de puits de forage est transporté dans un puits et expansé par l'application d'une pression. Le sabot flottant prend de l'essor vers l'extérieur, le long du montant du raccord du puits de forage.
