CA 2407404
The invention provides a method for treating a hydrocarbon-containing formation in situ, comprising applying heat to at least a portion of the formation via heater wells to pyrolyse hydrocarbons present in the formation to yield pyrolysis fluids and recovering the pyrolysis fluids from the formation, in which the heater wells are provided in a triangular pattern.
Cette invention concerne un procédé permettant de traiter in situ une formation renfermant des hydrocarbures. Ce procédé consiste à appliquer de la chaleur sur au moins une partie de la formation via des puits thermiques pour pyrolyser les hydrocarbures présents dans la formation en vue de l'obtention de liquides de pyrolyse et les extraire de la formation dans laquelle les puits thermiques sont disposés selon un agencement en triangles.
