INTRODUCTION

Advanced drilling engineering and operation analysis

Drilling solutions for challenging wells

Modeling wells with diverse and extreme complexity

Safe and cost-effective operational procedures

The demand for oil and gas is pushing the industry intoincreasingly challenging areas.

Much of the remaining reserves are located in deep water ordeep reservoirs with high or extreme pressure andtemperature conditions.

Successful drilling of challenging wells requires in-depth understanding of the hydraulics during allphases of the operation. The drilling process is highlydynamic and complicated to model; thus, much of the

dynamics have traditionally been neglected.

However, with diminishing operational margins, theimportance of dynamic effects is growing. Coupledwith increasing well construction cost from increasing

water depth or total well depth, software toolscapable of modeling the dynamics become essentialand strategically important.
