Coiled Tubing Applications


Coiled tubing (CT) has many programs within the petroleum industry, which encompass drilling (CT drilling), cementing, wellbore cleanup, oxidizing, and hydraulic fracturing. In contrast, the immoderate friction stress loss, because of the noticeably small tubing diameter and tubing curvature (which is assumed to be secondary to the drift) of CT, regularly limits the most available fluid injection rates. Therefore, it's of realistic significance to research the drift regularity and friction homes in CT

Targeted Groups

Engineers, Senior Operations Personnel, and Company Representatives with zero-to-intermediate well intervention knowledge who are assigned to evaluate, plan, and/or execute coiled tubing, slickline, or wireline interventions.

Course Objective

  • Discuss the right stress management system for any unique situation
  • Learn approximately the maximum normally used downhill gear and give an explanation for its characteristics
  • Understand a way to calculate and outline string limits for Coiled Tubing
  • Learn a way to paintings accurately with liquid nitrogen
