... of their components such as the CT string. Examining the impact of erosion for a certain pump rate on CT wall loss is a subject of investigation in this paper. The impact of erosion on CT has been studied for the past 10 years. Shah et al. (2004) studied the impact of erosion for fracturing through CT and its...

... for protecting the CT string and handling hydrogen sulfide (H2S) in the return stream were required. Third, CT string optimization was required to reduce potential abrasion failures. Avoiding CT failure was paramount as the string would be boat spooled onto the platform and any failure would severely impact...

... and converts that to a dynamic friction form along the CT string. The continuous hydraulic agitation reduces the onset of helical buckling and thus reduces CT helical contact points, resulting in lower resistance force. The development, design, and lab testing for the HDAT has been through extensive...

...Introduction Since the axial pushing force (surface slack-off weight) effectively reduces to zero at the lateral sections of horizontal wells, the CT string is tripped by using an additional pushing force (sliding regime). Such a situation makes the friction coefficient between the CT string...

Design Optimization CT String CT strings are one of the biggest components of any unconventional project's consumable, comprising approximately 30 to 40% of the CT's variable cost per stage. Therefore, selecting the proper CT string is crucial to achieving economically...
