Offset Wells Data Analysis and Thermal Simulations Improve the Performance of Drilling HPHT Well

Abstract

To drill new HPHT development wells safely, an exact estimate of their stability is essential. Analyzing previously drilled offset wells can assist in this determination, eliminating any stratigraphic column issues and saving nonproductive time. The challenges found with offset wellbores, their consequences on well design, possible remedies, and preventative measures are discussed in this paper. It examines drilling data from offset wells in order to discover, diagnose, and treat serious issues. Furthermore, thermal simulation was done in order to study the temperature distribution of the wellbore, annuli and fluids during drilling, tripping, circulation, logging, casing and cementing in HPHT zone.
