Noble Energy Inc., Houston, reached the targeted upper and middle Miocene objectives but did not encounter commercial hydrocarbons in the Madison exploration well in the Gulf of Mexico, the company said.
The well, spud in late October, was drilled to a total depth of 16,859 ft on Mississippi Canyon Block 479. The drilling rig has since been released.
Noble previously reported that Madison contains unrisked gross resources of 45-120 million boe.
Noble operated the well with 60% working interest alongside Stone Energy Offshore LLC with 40% (OGJ Online, Dec. 4, 2014).
