Abstract

A vent screen pressure deployment tool and method for use in running tubular members into a pressurized well. The apparatus comprises a top sub and a stinger. The top sub is adapted for connection to the upper end of a tubular member, such as a vent screen. An upper end of the top sub is adapted for connection to a conveying tool, such as a slick line deployment tool, and the top sub defines a collet recess therein. The stinger comprises a locator sub adapted for connection to the lower end of another tubular member and a collet sub shearably attached to the locator sub. The collet sub has a plurality of flexible collets thereon adapted for latching engagement with the collet recess when aligned therewith, thereby providing a latched connection between the tubular members.
