The Opalinus Clay is notable in Switzerland as being the selected host rock for deep geological disposal of radioactive waste. Since early 1990’s, this argillaceous mudstone formation Jurassic age has been intensively studied within framework national and international projects to characterize its geological, hydrological, mechanical, thermal, chemical, biological properties. While there no for...

Injection of formation water can cause formation damage due to the migration of fines, clay swelling, gas bubble formation, as well as the precipitation and dissolution of minerals. Because the injected water has approximately the same chemical characteristics as the production water, fines migration and gas bubbles will be the main sources of formation damage. The near vicinity of the well wil...

Texture synthesis aims to define and reproduce discriminating image features. These features are used to associate with and differentiate between two textures. Often texture is composed of a pattern with an element of randomness in each feature’s appearance, position and orientation. The goal is to imitate the sample texture in such a way that sample and synthesised texture are perceived to be ...

Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive way. Such editing operations would require a low-dimensional but expressive model for appearance that exposes only a small set of intuitively editable parameters (1D-sliders, 2...
