Recently, an intrinsically safe, high pressure, gas gun was developed and presented at the 2010 SWPSC. This development was certified for Div 1/Class 1 well locations. Extending this development was the need to manufacture this gun for 5000 psi well service for operations in hydrogen sulfide and carbon dioxide fluid service. This presentation will discuss the industry requirements for materials selection according to standard NACE MR0175/ISO 15156. Also presented will be the main gas gun components in the fluid path and the appropriate selection of materials resistant to cracking and corrosion in this service.
