Dry Gas Internal Corrosion Direct Assessment (DG-ICDA) relies upon the ability to correctly identify locations where water accumulation is expected to occur. The two key factors impacting detailed examination location selection are superficial gas velocity which is used to calculate the critical angle and the pipeline inclination angle. Therefore appropriately identifying these two factors is crucial to properly selecting locations of expected water accumulation. This paper discusses performing detailed analysis of flow data to identify both the maximum superficial gas velocity and typical superficial gas velocity. Various field techniques that can be used to increase confidence in the calculated pipeline inclination angle are also discussed.
