Grand Rapids is one of the major oil sand formations in Western Canada. As in-situ production of bitumen using Steam Assisted Gravity Drainage (SAGD) continues to grow, oil sands in the Grand Rapids formation is beginning to attract more industry attention. This paper focuses on the performance of two well pairs at the Blackrod SAGD Pilot Project operated by BlackPearl Resources Inc. The geology of the Lower Grand Rapids formation, sand control selection, and operational practices will be discussed using both laboratory and field data. Petrographic data of oil sand core before and after steam injection and the potential thermal formation damage mechanisms are discussed. Differences in the performance and the key learnings of the two well pairs are presented.

The findings of the work are to be implemented during the next phase of the project and are thought to be useful to other operators developing oil sands located in the Grand Rapids formation or similar oil sand and heavy oil deposits.
