Laser, Mono-Diameter Drillstring with Resin Spray Casing Completions

Abstract

The industry has come a long way since the inception of drilling from cable too rig to rotary drilling. The method of drilling has not changed at all in the last couple of decades. The advancement of technologies have lead to development of high power lasers which can be used to blast through the rock at rates greater than 200 ft/hr. We would like to introduce the a new laser drilling system which can drill a mono diameter hole and simultaneously build a casing around the wellbore using high pressure spray devices to spray a heat setting resin which is then pressed using a heated drum roll to give a perfect smooth casing wall. A second jet with low temperature air is used to cure the resin thus setting it faster than the conventional way.The resin is capable to sustain pressure up to 4885 psi and thus making it a likely candidate for HPHT wells. It is highly resistant to chemical corrosion and is non-rusting thus enhancing the life of the completion. The complete drill string design would be discussed in detail providing the next 21st century tool for the drilling industry to drill through any possible formation encountered.
