Title: Successful high angle drilling in the Statfjord Field

The original drilling design criteria for Statfjord field development set an upper limit on wellbore inclination of 60/sup 0/. This figure was derived by considering the special drilling problems found on Statfjord and technological limitations. By developing engineering operational procedures and introducing new technology, wells can be drilled routinely at sail angles between 60/sup 0/ - 70/sup 0/. This paper, therefore, elaborates upon the special drilling problems encountered in the area and describes engineering and operational solutions which were developed to extend the maximum reach of wells. In addition, it describes the evolution of drilling on Statfjord and documents the impact of advances.
