Rango Energy Inc. announced that as of 6 am Pacific Time, June 10, 2013, drilling has reached a depth of 5,761 feet on the planned 13,000 foot first well at the Kettleman Middle Dome project. The project covers over 11,300 acres of a producing oil field sandwiched directly between two giant 400+ million barrel fields in the San Joaquin Basin, Central California. The target for well #17-18 is the oil rich McAdams sandstone formation, a 900 to 1,200 foot thick Eocene age reservoir located at a depth of approximately 12,000 feet.

The McAdams sandstone has been a prolific producer in the adjacent Kettleman North Dome field, producing at an average of over 2 million barrels per well. Other oil bearing formations that have been mapped directly at the KMD project are the Kreyenhagen Shale, the Vaqueros sandstone and the much-publicized, Monterey Shale. Currently the well is drilling through the renowned Monterey Shale, the top of which was reached at a depth of approximately 5,500 feet.

Intermediate casing was successfully set into the Monterey at a depth 5,596 feet and drilling continues within the formation.
