Hydraulic Coiled Tubing Tractor Technology Extends the Accessibility of Coiled Tubing in Horizontal Wells, Allowing Better Well Intervention – Case Study

Abstract

Recent advances in drilling technology have resulted in longer horizontal wells and have increased the complexity of well completion; the well intervention is becoming more challenging. Conventional techniques are no more adequate to access in long openhole horizontal sections when using coiled tubing to perform intervention works such as stimulations, logging and zonal isolation. This essay was created to assess the capability of a coiled tubing string to reach the desired depth in a projected long horizontal well. The scope of this essay is to provide a complete set of simulations to predict the tubing forces for two proposed different diameters of openhole section. Such simulations can serve as guidelines for completing the well.
