... Abstract The narrow drilling window of a High Pressure-High Temperature (HPHT) formation creates challenges in managing bottom hole pressure (BHP) during drilling and tripping operations. Managed Pressure Drilling (MPD) techniques have proven effective in accurately controlling downhole...

... the research is the desire to make use of the data that is already provided for the benefit of increased lifetime of the connections and the reduction of drill string failures, especially for drilling under extreme downhole conditions like long horizontal, HPHT or deep water. This paper presents a short...
