This document describes studioSL, a modular application for pre- and post-processing simulation models of oil, gas, and water flow in the subsurface. It uses the NetBeans Platform for its graphical user interface and modular design. Key features include 2D/3D visualization, support for multiple simulator file formats via its PE Commons API, and exporting to common file types like Excel. The application leverages many NetBeans Platform features and aims to improve user feedback on crashes and suggestions. Future work may include remote job launching capabilities.
