Title: Re-entry drilling from existing wellbores often is viable due to economic, environmental and surface logistics concerns
Text: Coiled Tube and Slimhole Drilling: "Due to economic, environmental, and surface logistics concerns, re-entry drilling from existing wellbores is often an extremely viable solution to horizontal development in existing reservoirs. By utilizing an existing wellbore, many of the costs can be avoided and often troublesome formations are already secured behind casing."
