Casing and liner running and cementing operations in high angle wells with long open hole sections pose seemingly diverse sets of challenges irrespective of location and drilling environment. The fluvial loose formations predominant in the arctic region of Russia and most parts of Siberia provides more than adequate tests and constraints to modelling, understanding and accommodating the risks associated with such operations as this. This is further complicated with no reliable nor consistent information regarding representative geo-mechanics models or failure plains within the region.

This paper looks at modelling casing1,2,3,4  running operations and the impact of perceived friction factors and choice of accessories on the overall out come of the operation. The objective is to better understand the modelling constraints and the importance of certain parameters and assumptions in the final solutions. Successes, failures and lessons learned will be articulated to provide key best practices or design considerations for similar or future projects. Furthermore, we will also evaluate the technologies available within the area and the impact of technology adoption on both the ability to land casing/liner and provide adequate cementing.
