Connacher Oil & Gas Ltd., Calgary, raised bitumen production and lowered steam injection rates in a test of a proprietary method for enhancing steam-assisted gravity drainage with injection of solvent at its Algar oil sands development in Alberta.

The process, which Connacher calls SAGD+, raised the average rate of bitumen production in the Algar 203-1 well pair by 30% in the first 4 months of 2013 over the 4 months prior to the beginning of the test in May 2012. The company reported steam injection was about 10% less between the comparison periods. Solvent-injection rates over the entire test period have averaged 6% of the steam volume injected.
