NSAI Issues Report on Company's North Slope Shale Oil

386 Million Barrels in Alaska Acreage

SAN DIEGO, Aug. 21, 2013 (GLOBE NEWSWIRE) -- Royale Energy, Inc. (Nasdaq:ROYL)
today, in cooperation with Rampart Energy, is pleased to announce the results
of a study performed by Netherland, Sewell & Associates, Inc. Worldwide
Petroleum Consultants, (NSAI), www.netherlandsewell.com, to evaluate the
prospective resources in their shale acreage on the North Slope of Alaska.
Using available data from existing wellbore penetrations and analog shale
plays, they determined that the acreage is a qualified Prospective Resource
with an average recovery rate of 3,995 barrels of oil per acre from the
combined shale intervals.


Based upon estimated drilling density of 160 acres per well, this equates to
639,119 barrels of oil per well drilled. Total Original Oil in Place and Total
Recovery per acre is divided between the three intervals as follows:


        OOIP Total (BBL/acre)            EUR Total (BBL/acre)
        Low     Best    High     Mean    Low  Best   High   Mean

Total   14,288 66,965 167,220 80,473 632 2,936 8,473 3,995

The report covers 96,882 acres including 39,539 acres that the companies have
agreed to jointly develop (Western Block), 17,139 acres owned by Royale
(Central Block) in which Rampart has future rights to acquire, and 40,204
acres (Eastern Block) owned exclusively by Royale.The table below represents
the total Estimated Ultimate Recovery (EUR) from the combined acreage:

Preparation for a seismic survey has already begun with the field work on an
archeological survey of the area. Final engagement of the contractor is
expected imminently, and data is expected to be available by the second
quarter of 2014.

                       undiscovered accumulations by application of future
Prospective Resources  development projects. Prospective Resources have both
                      an associated chance of discovery and a chance of
