Noble Energy announces Bright exploration results in Gulf of Mexico Noble Energy announced that the Bright exploration well in the deepwater Gulf of Mexico reached the targeted Upper and Middle Miocene objectives and did not encounter hydrocarbons. Drilled to a total depth of 13,500 feet on Atwater Valley 362, the well has been plugged and abandoned. Full well assessment and the integration of drilling results into the Company's geologic models is ongoing to determine forward exploration plans on the recently acquired Atwater Valley acreage. BP Exploration & Production operated the well with 50% working interest and Noble Energy had the remaining 50%. The company expects third quarter 2014 exploration expense to remain within guidance of $150M-$250M.
