Media Advisory: Crude Solutions Launches Patent Lawsuit Against MEG Energy

FOR IMMEDIATE RELEASE

April 30, 2014 – Crude Solutions Launches Patent Lawsuit Against MEG Energy

Crude Solutions Ltd. (CSL), a research and development firm for the oil and gas industry, has sued
MEG Energy Corp., accusing MEG of infringing CSL’s patent rights.

Crude Solutions Ltd. (CSL), an Edmonton based research and development firm
for the oil and gas industry focusing on steam-assisted gravity drainage (SAGD) extraction
techniques, has sued MEG Energy Corp. (MEG), accusing MEG of infringing CSL’s Canadian
Patent No. 2,800,746 with MEG’s RISER project and eMSAGP process.

The patent infringement lawsuit, filed on Tuesday, April 29, 2014, in the Federal Court of Canada,
states that CSL is the owner of patented technology relating to exploiting pressure gradients in
SAGD oil recovery operations. The lawsuit goes on to allege that MEG had explicit notice of the
proprietary nature of the technology within days of the patent being issued and had constructive
notice as of the publication of the patent in November 2012 and that MEG continues to make use of
its infringing processes in wanton and outrageous disregard of CSL’s rights. MEG’s alleged
infringing eMSAGP process has been and is being implemented in all phases of its Christina Lake
operations and MEG has indicated its intention to implement this process in all of its recovery
operations.
