Royale Provides Source Rock Estimate

SAN DIEGO, Aug. 26, 2013 (GLOBE NEWSWIRE) -- Royale Energy Inc. (Nasdaq:ROYL)
has released a third-party estimate of its North Slope acreage.

At an average recovery rate of nearly 5 percent and mean oil-in-place of some
80,473 barrels per acre, the three source rock intervals underlying the
96,882-acre leasehold would yield 3,995 barrels per acre, according to
Netherland, Sewell & Associates, Inc.

The global consulting firm provided an oil-in-place range of 14,288 to 167,220
barrels per acre for the acreage, which would yield recovery of 632 to 8,473
barrels per acre.

With spacing at 160 acres per well, the mean estimate would yield an average
estimated ultimate recovery rate of 639,119 barrels per well. By comparison,
the U.S. Energy Information Administration Annual Energy Outlook 2012 provided
average EURs of 550,000 barrels for a Bakken formation well and 280,000 for an
Eagle Ford shale well.

The San Diego-based Royale Energy is developing its acreage with
Australia-based Rampart Energy Ltd. The farm-in deal initially calls for
Rampart to fund two wells with horizontal laterals in the 39,539-acre Western
Block of the acreage by March 31, 2015.

The report estimates this block contains a mean EUR of nearly 158 million
barrels.
