  • Publication number: 20180195371
    Abstract: A method for expanding a lower bell section of an expandable tubular to a larger diameter than upper parts thereof utilizes an expandable bell cone (1) with circumferentially spaced segments (2) that expand in response to axial force and automatically retract in response to removal of the axial force, wherein gaps (A) are present between the expanded segments (2) and the tailends (2A) at the gauge of the segments are slightly skewed to mitigate the effect of the gaps (A) on the flattening of the expanded bell sections between the segments (2).
