Circulation loss can occur at different positions during drilling, which has different effects on
the wellbore temperature distribution. To ensure the safety and effectiveness of the drilling …

How good are your models? Can they be used to improve your drilling processes? These
are questions often posed in relation to real-time model applications, including models …

A telemetry drill string system consists of a string of wired drill pipes, and high‐frequency
signals pass the adjacent drill pipes through inductive couplers. Such a system is used to …

This paper will summarize the development of a range of drilling tools for use in a wired
drillstring. The paper will focus on the history and learnings from the engineering design …

This paper focuses on the real-time data that are available from the drilling operations for oil
and gas. In addition, this paper focuses on the data from the operations on the Norwegian …

The history of drilling engineering applications has revealed that the frequent operation
problems are still common in oil well practice. Blowouts, stuck pipes, and well leakages are …

For the time being the O&G industry relies on simple procedures and models to get an idea if
the way it operates is to some extend reasonable respectively efficient or not. The …
