Jun 14, 2013 - Noble Energy announced results from the second appraisal well drilled on the Gunflint discovery in Mississippi Canyon block 948 in the US Gulf of Mexico. The well was drilled by the Ensco 8501 (DW semisub) to a depth of 32,800 feet. A net pay of 109 feet was encountered within the primary reservoir targets. Logging results confirmed an estimated gross resource range of 65 to 90 MMboe in the main target. An adjacent three-way structure is a candidate for future exploration. Noble and its partners are likely to develop the discovery as a subsea tieback with project sanction expected later 2013.
