Abstract

Now a days deep hydrocarbon reservoirs are exploited through onshore and offshore platforms, which was difficult a few decades ago. This development is due to the technological developments in creating a drill string, which can withstand greater weights and can drill kilometers long. The drill string in well directions, which needs to withstand against shear pressure (wind off), ductile pressure (separating), breakdown and the preload applied from joint make-up force legitimately influences the static pressure dispersion inside the connection

Keywords

Drilling string connections, fatigue failure, stress concentration factor, down hole failure.
