A repository of open-source drilling models, test cases, and benchmarks for deep drilling problems. Models are distributed under the MIT license and are provided as-is and free of charge.
Version 0.1 was released on September 1, 2021. Additional models are being added regularly.
OSDC hosts a monthly seminar series highlighting the development, validation, and use of drilling modeling with speakers heralding from industry and academia.
WOB Transfer and Buckling Data Analytics – Ysabel Witt-Doerring – May 16th, 2022In this talk, Ysabel will present surface and downhole data from a particularly difficult horizontal well in Oklahoma that presented challenges with weight transfer and drillability.
Stick slip vibrations in drilling: modeling, estimation, avoidance – Jean Auriol and Florent Di Meglio – April 25th, 2022In this talk, we present some recent developments for estimating and controlling the torsional motion of a drilling device. We introduce first the stick-slip phenomenology and explain its physical causes. We present a mathematical distributed model that can accurately describe the torsional motion of the drilling device.
Implementing Soft String and Stiff String Models for Torque and Drag Calculations – Darlington Etaje – March 21st, 2022Soft string and stiff string models are two different mathematical models which are used for torque and drag analysis. They were developed to describe the mechanical behavior of the drill string inside the borehole, and they have their own theoretical background and assumptions.
