Rodinia Oil Corp. Confirms Rig Mobilization for Officer Basin
Drilling Program 
CALGARY, ALBERTA -- (Marketwire) -- 04/20/11 --   Rodinia Oil Corp.
("Rodinia" or the "Corporation") (TSX VENTURE: ROZ) is pleased to
announce that Ensign Australia Pty. Limited, a subsidiary of Ensign
International Energy Service ("Ensign International") has begun
de-mobilizing its heavy triple Rig #16 from the Cooper Basin, South
Australia. Ensign International is mobilizing the rig to the Officer
Basin in South Australia for Rodinia. 
Drilling Program Update  
Ensign International's Rig #16 has begun mobilizing for the
approximately 2,000 kilometre journey to the Officer Basin to
commence drilling of "Mulyawara 1", the first well in Rodinia's
exploratory drilling program. Mulyawara 1 is expected to spud in
mid-May and drilling is expected to take approximately six weeks. 
Mulyawara 1 is located in the northwest corner of PEL 253 (South
Australia) and will test a structure of approximately 36.3 square
kilometres (per horizon) in size identified on seven seismic lines.
This well will target five potential reservoirs, the deepest of which
is the aeolian Pindyin sandstone (also called the sub-salt unit).
Rodinia has an 80% working interest in this well and prospect and is
the operator. 
Rodinia's contract with Ensign International includes four firm wells
with the option for up to four additional wells in the Officer Basin. 
Report by Ryder Scott Company Canada  
According to a report (the "Ryder Scott Resource Report") prepared by
Ryder Scott Company Canada (independent oil and natural gas reservoir
engineers), dated January 12, 2010 and effective December 31, 2009,
the unrisked, undiscovered, prospective (recoverable) resource, based
on a best (P50) scenario, for Mulyawara 1 is estimated at 2.7 BBbls
(gross) of oil. 
The Ryder Scott Resource Report on the resource potential of the
Officer Basin describes the prospective (recoverable) portion of
"Undiscovered Resources", as defined by the Canadian Oil and Gas
Evaluation Handbook and does not represent an estimate of reserves.
The Ryder Scott Resource Report is compliant with National Instrument
51-101 "Standards of Disclosure for Oil and Gas Activities" ("NI
51-101"). There is no certainty that any portion of the resources
will be discovered. If discovered, there is no certainty that it will
be commercially viable to produce any portion of the resources. 
Prospective resources are those quantities of petroleum estimated, as
of a given date, to be potentially recoverable from undiscovered
accumulations by application of future development projects.
Prospective resources have both an associated chance of discovery and
a chance of development. Prospective resources are presented as
unrisked prospective oil resources. The term unrisked means that no
geological risk (play risk) has been incorporated in the hydrocarbon
volume estimates. 
Additional information on the prospective resources can be found at, in the Long Form Prospectus dated May 20, 2010 filed
under Rodinia Oil Corp.
