Abstract
Linvention décrit des techniques pour une récupération sur place dhydrocarbures, par ex., par un drainage par gravité au moyen de vapeur (SAGD), dans lesquelles un générateur de vapeur à passage direct (OTSG) produit de la vapeur pour injection dans un réservoir et un écoulement de purge qui est filtré, par ex., en utilisant une nanofiltration. Le flux deau filtrée peut être recyclé directement dans un réservoir deau dalimentation de chaudière. Certains contaminants peuvent être retirés de lécoulement de purge, comme une matière organique dissoute, du calcium, du magnésium et/ou de la silice.
