Directional drilling - advanced trajectory modelling / Направленное бурение - расширенное моделирование траектории

Drilling operations are a significant cost in the process of recovering hydrocarbons. The operations are advanced and associated with large HSE and financial risks. The main objectives in a successful drilling operation are to construct safe and economically efficient wells, but the success also depends on hitting the target. As the drilling operation has very high standards of execution, a good drilling operation depends on a good well plan.

The planning phase is a large and complex process as it engineers all aspects of a drilling operation. This is key to create safe and economically efficient wells. Well trajectory planning is a mixture of many parameters but in the end it comes down to identifying the most optimum well path. That means they should be based on exact mathematical calculation models, to precisely calculate well bore trajectories. The industry uses a number of different planning tools that makes it possible to calculate and plan complex well path trajectories. Very few studies have addressed this topic in a systematic manner.
