The future is Low Shear

Welcome to Low Shear School!


Here you can learn about shear theory in liquids, low shear equipment and technologies used in the Petroleum industry. Low Shear School is a living portal, where everyone can learn about low shear technologies, and are welcome to share their knowledge, participate in discussions around interesting topics, and to contribute to the development of this portal.
