... results can be obtained in most cases, but he mostly focused on pools with vertical wells. The purpose of this paper is to present results of several heavy oil waterfloods in Canada that use horizontal producers and injectors. The production performances of eight heavy oil pools where waterflood has been...

... wells. Four pilot surface to in-seam well pairs were successfully drilled and commissioned in 2012 and 2013. Based on the performance of these pilots, further development of the coal seam gas field converted from stimulated vertical wells to horizontal wells from 2015 onwards. Surface-in-seam (SIS...
