A method for treating a tar sands formation is disclosed. The method includes providing a drive fluid to a first hydrocarbon containing layer of the formation to mobilize at least some hydrocarbons in the first layer. At least some of the mobilized hydrocarbons are allowed to flow into a second hydrocarbon containing layer of the formation. Heat is provided to the second layer from one or more heaters located in the second layer. At least some hydrocarbons are produced from the second layer of the formation.
L'invention concerne un procédé pour traiter une formation de sables bitumineux. Le processus comprend la fourniture d'un fluide de drainage à une première couche contenant des hydrocarbures de la formation pour mobiliser au moins certains hydrocarbures de la première couche. Au moins certains des hydrocarbures mobilisés peuvent s'écouler dans une seconde couche de la formation contenant des hydrocarbures. De la chaleur est fournie à la seconde couche à partir d'un ou de plusieurs dispositifs de chauffage situés dans la seconde couche. Au moins des hydrocarbures sont produits à partir de la seconde couche de la formation.
