MIDLAND, Texas, Oct. 21, 2013 (GLOBE NEWSWIRE) -- Diamondback Energy, Inc. (Nasdaq: FANG ) ("Diamondback") today announced initial results from its Digger 601H Clearfork Shale well in Andrews County which tested at a 24 hour rate of 611 Boe/d (87% oil) from a 7,541 foot lateral.

"Since the onset of first oil in early September, the oil rate has continued to increase, reaching a maximum rate to date of 611 Boe/d (87% oil) on October 15 ^th ," said Travis Stice CEO of Diamondback. "This well has demonstrated a different production profile than our typical horizontal Wolfcamp B wells that tend to peak much earlier in the initial flowback period."

Stice continued, "Further testing will be required to validate reserve estimates, but the results so far are encouraging."
