Titanium Drill Pipe for Ultra-Deep and Deep Directional Drilling

This paper discusses the modeling and analysis of 5, 5-1/2, 5- 7/8 and 6-5/8 in. titanium drill pipe in ultra-deep and deep directional drilling programs. Using a computer based drill string simulator, modeling a representative deep directional well, titanium drill strings were compared to the same size steel drill strings using two design criteria: margin of over pull and hydraulic efficiency.
