Title: Advanced geothermal foam drilling systems (AFS) -- Phase 1 final report, Part 1

Abstract

An advanced coiled-tubing foam drilling system is being developed where two concentric strings of coiled tubing are used to convey water and air to the hole bottom where they are mixed together to produce foam for underbalanced drilling. This system has the potential to significantly reduce drilling costs by increasing drilling rates (due to the motor being powered by water), and reducing compressor and nitrogen costs (due to lower gas pressures and volumes).
