Rodinia Oil Corp. Confirms Rig Mobilization for Officer Basin Drilling Program 
CALGARY, ALBERTA--(Marketwire - April 20, 2011) - 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
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.
