A cost-effective and innovative test setup serves to qualify the new, highly integrated formation evaluation tools. This setup<br>shall help reduce the risks associated with the tool development and later shall integrate into the manufacturing test chain.<br>The setup is a 4.5 meter high stack of quarried rocks immersed in fresh water. From bottom to top the stack includes three<br>equally thick layers: a porous sandstone, a low-porosity limestone and an azimuthal combination of both. A high quality 10.5<br>inch diameter hole traverses the three layers. The measurements are recorded in various conditions to characterize the tool’s<br>azimuthal and vertical response.
