1 SummaryConocoPhillips Canada (formerly Gulf) holds six oil sand leases in theSurmont area covering 580 square ilometres! "hese leases# locatedapproximately 50 ilometres south$southeast of the City of %ort&c&urray# contain an estimated '5 illion arrels of itumen in place!Commercial development of these leases as until recently not

possile due to limitations of the existing technology!

"he initial evaluation or regarding use of the S*G+ process atSurmont as performed y the ,il Sands and -esearch +ivision(,S.-+) of the *lerta +epartment of /nergy (formerly *,S"-*)! "hestudy recognied that S*G+ (as developed at 1"%) could not edirectly applicale to Surmont and that a research and development(-.+) program at Surmont as required to advance the S*G+technology! *lthough some features of the S*G+ process have eenpatented# many unique questions remain to e ansered in order todevelop this concept for Surmont! %or this reason# the ,S.-+ study

recommended that an experimental pilot e developed for Surmont toaddress the areas of uncertainty! 2egotiations ere initiated to havethe *lerta +epartment of /nergy participate in funding the pilot aspart of their ongoing research commitment! ConocoPhillips3 SurmontPilot as approved for 4/"P funding in '005!

*lthough a small commercial facility egan operation at Surmont in'00# there are still many unnons that ill a6ect the developmentat Surmont! "he ells at the Surmont Pilot have 7ust egun to shosigns of contact ith the overlying thief ones! 1nderstanding theimpact of the thief ones is critical to the Surmont +evelopment!
