The present invention generally relates to a cone system having a cone segment capable of deflecting in response to a restriction or obstruction encountered while expanding a tubular. In one aspect, an expansion cone system is provided. The expansion cone system includes a mandrel and two or more pockets disposed circumferentially around the mandrel. Each pocket is at least partially defined by a fin member. The expansion cone system further includes a cone segment coupled to each pocket. Additionally, the expansion cone system includes a biasing member disposed between the mandrel and the respective cone segment. In another aspect, a method of expanding a wellbore tubular is provided.

Compliant cone system

The present invention generally relates to an apparatus and method for expanding an expandable tubular assembly in a borehole. In one aspect, a system for expanding a tubular having an anchor portion in a borehole is provided. The system includes a running tool configured to position the tubular in the borehole. The running tool including a first expander configured to activate the anchor portion by expanding the tubular to a first diameter. The system further includes a second expander configured to expand the tubular to a second larger diameter, wherein the second expander is movable between a retracted position and an expanded position. In another aspect, a method of expanding a tubular having an anchor portion in a borehole is provided.
