Blind wells are commonly installed in areas where site access for an exit hole is unavailable. Typically blind wells are installed under chemical manufacturing facilities, airports, pond/lagoons and in highly urbanized areas. Blind well advantages include:

• Less materials required
• No exit hole location needed
• A surface casing can be cemented through the curve section
• Wells can be drilled from offsite areas without creating any structural surface impact
• No requirement for pipe on the exit
• Reduced hazards from elimination of pipe at the exit
