Description of Recovery Process The Pelican Lake SAGD Pilot uses the dual-horizontal well SAGD (steam assisted gravity drainage) process to recover the bitumen from the Grand Rapids A formation Two horizontal wells one above the other ~5m apart Steam injected into the upper well to heat the bitumen and allow gravity to drain to the lower well Oil and water emulsion pumped to the surface and treated
Original Objectives Test longer well lengths (1200m+) Evaluate start up procedures Determine peak rates from the Grand Rapids Reservoir management with the lean zone

Producer Suction Ports: Discussion The suction ports were designed to increase the capacity of the 4.5 tubing in the horizontal section while minimizing the pressure drop in the annulus between the 7 liner and the 4.5 tubing. Fluid entering the liner upstream of a suction port will enter the 4.5 tubing through that port and thus be removed from the annulus before the next suction port. This system works very well when the well pair is uniformly heated. However, in this case there is a hot spot close to the heel of the producer and it was desirable to get the fluid from the hot spot to the toe thereby promoting uniform heating along the producer liner. The suction ports made it difficult to achieve this and were thus removed. We also needed to steam the producer and the suction ports which impeded steam to the toe.

Evolution of SAGD Well Pair Completions Wells 26P01, 26I01 Injector and Producer had similar completions during start up circulation. After start up, producer was re-completed with ESP and suction ports in the production tubing which extends to the toe. The injector was re-completed with 15 steam splitters to promote uniform steam injection down hole. Suction port design was not optimum and the producer was later re-completed with the suction ports removed.

2010 & 2011 3D/4D Seismic Programs
Scheme Performance Subsurface Subsection 7 Pelican Lake SAGD Pilot 2011 Annual Performance Presentation
Scheme Performance Prediction Well pair performance prediction was based on a correlation using a modified Butler s equation and sensitivities from reservoir simulation. CSOR was predicted for the well pair from published correlations for CSOR (Edmunds and Chhina 2002)
Wellhead Steam Quality Steam quality injected into the wells is estimated at 98% Steam is generated at 7500 kpa and saturation temperature of 290 C Actual wellhead injection pressure depends on steam injection rate but has not exceeded 5,000 kpa (264 C) to date
Summary Operating for ~ 15 months Progress has been slow: Had to deal with many unplanned issues Excellent learnings to date: Very relevant to the start up of the commercial project Good reservoir performance: Mechanical issues limited wellbore effectiveness - still less than ½ of the well length Second well pair drilled to achieve original pilot objectives. Major focus is start-up
