Abstract
In one embodiment, a method of installing tubular conduits (for example, casing, liners, sand screens) into a deep or highly deviated borehole is disclosed. A lower plug () is attached at one end of a portion of a tubular conduit. This end is inserted into a borehole. After insertion into the borehole the desired length of conduit intended to resist internal collapse forces and be substantially buoyant, a plug () is attached at the upper end. The plug has a valve () designed to enable fluid communication between the pressurized fluid section and the insertion string. A pump is attached to the valve and the pressurized fluid is added to the pressurized fluid section, after which the valve is closed. After the tubular conduit is inserted to the desired depth, the valve is opened allowing the pressurized fluid flow out of the pressurized fluid section. Conventional well construction activities may then resume.
