CAGE is a development and demonstration project of several cost-saving and output-improving installation technologies. The objective is to demonstrate a new GE concept, suitable for limestone areas and target depths of 1 to 2.5 km. The demonstration contains the following innovations: 

• Crane-based drilling
• Enhanced Casing Installation (ECI / ECCI) technology (Casing While Drilling)
• Lightweight and corrosion-resistant High Strength Composite Casing (HSCC)
• Acoustic Multi-Sensor Parameter Analysis (MSPA) supported Radial Drilling
• Airlift technology to replace the costly Electrical Submergible Pump  

CAGE has three main work packages: 

1. preparatory studies (geology, well design, surface installations, business case, etc.)
2. technology demonstration (see above) @ reallocation
3. the development of the full composite mechanical connection (major improvement of ECCI).
