Abstract

métodos para fazer uso eficiente de vapor em um processo de drenagem gravitacional assistida com vapor (sagd) para recuperar óleos pesados a partir de areias betuminosas e depósitos de petróleo similares são divulgados. os métodos utilizam um surfactante para gerar espuma de vapor em maneiras que maximizam o uso eficiente de vapor. em alguns aspectos, a espuma de vapor é usada em capas de gás ou camadas de água que residem acima de câmaras de vapor para impedir perda de vapor a partir da câmara de vapor. o uso predominante de vapor relativamente seco em processos de sagd torna difícil encontrar maneiras de introduzir surfactantes e gerar espuma de vapor. no entanto, diminuir a mobilidade do vapor ao converter pelo menos uma quantia dele em espuma permite que o furo de poço e as câmaras de vapor acima do local de injeção sejam mais completamente desenvolvidos, provejam transferência de calor mais efetiva para o óleo pesado e as pedras, aprimore a produção e permite a recuperação do óleo pesado com uma quantidade mínima de uso de vapor.
