    Abstract: The present invention provides a simple debris removal apparatus (200) for use in a wellbore. In one aspect of the invention a modular, interchangeable venturi (210) is provided which can be retrofit into an existing debris bailer having a filter and a debris collection container (225). In another aspect of the invention, a venturi is utilised to create a negative pressure in a wellbore sufficient to actuate a retrieval tool for a downhole device. In yet another aspect of the invention, a combination tool is provided which can evacuate debris in a wellbore, thereby uncovering a downhole device which can then be removed in a single trip. In yet another aspect of the invention, a debris removal apparatus is provided with a method for utilising the apparatus in a wellbore on coiled tubing.

    Abstract: 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 (560) having an anchor portion (550) in a borehole is provided. The system includes a running tool (535) configured to position the tubular in the borehole. The running tool including a first expander (520) configured to activate the anchor portion by expanding the tubular (525) to a first diameter. The system further includes a second expander (540) configured to expand the tubular (525) to a second larger diameter, wherein the second expander (540) 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.
