A method is described for producing hydrocarbons from a portion of an underground formation bounded by at least two substantially vertical wells and at least one substantially horizontal well, comprising: injecting a thermal fluid into the formation through a first substantially vertical well; producing fluids from a substantially horizontal well located within the underground formation; the horizontal well extending from an area near the first vertical well to the vicinity of a second substantially vertical well penetrating the formation; the horizontal well produced fluids only being produced from a first perforated interval in the horizontal well in the vicinity of the first vertical well; ceasing production from the first perforated interval of the horizontal well and producing fluids from a second perforated interval of the horizontal well which is farther from the first vertical well than the first perforated interval; continuing to move the production of fluids through the horizontal well to perforated intervals successively farther away from the first vertical well than the preceding production perforated intervals; after fluids have been produced through a perforated interval in the vicinity of the second vertical well, producing fluids through the second vertical well.
