A two person delegation was formed in 2008 to continue the advanced well drilling techniques begun in 2007. During a 7-day trip in 2008, the drill rig was re-tooled to make operation more efficient for the North Korean drill crew. A tool guide was fabricated to aid in starting wells and to provide another measure of safety for the crew. Several of the wells drilled since 2007 were inspected and approved. Several new drill sites were surveyed for future drilling after the Wellspring delegation left. Approximately ten additional wells were drilled in 2008.
