The ever‐increasing quest to identify, secure, access, and operate oil and gas fields is
continuously expanding to the far corners of the planet, facing extreme conditions toward …

A coupled drill string dynamics model presents an opportunity to understand, replicate and
potentially control the vibrations occurring along a drill string in a deep well. This paper …

An algorithm for regulation of the vertical penetration rate in rotary drilling systems is
developed under the assumption that parameters of the rock-bit interaction as well as those …

The objective of the auto driller is to maintain stable control of drilling parameters to reduce
the time per stand and increase single run sections when possible. Large variation in rate of …

As a follow-up to the challenge set forth by to create an open-source drilling community for
modelling and data, this paper presents the charter, contribution methods, workflows, and …

The objective of this study is to present a novel rock formation identification model using a
data-driven modeling approach. This study explores the use of real-time drilling data to train …

Throughout the history of oil well drilling, service providers have been continuously striving
to improve performance and reduce total drilling costs to operating companies. Despite …

For the last thirty years, mathematical modelling has been used to develop software
solutions that support drilling engineering activities at the planning stage of drilling …

The ability to predict the response of a drill bit to the topside axial and rotational velocities of
the drill-string is a prerequisite for any system aimed at automatically controlling the drilling …

Simulation of drilling processes involves the seamless integration of strongly coupled
physics, numeric, and economic models. Operators desire advanced drilling simulation …
