Abstract
Disclosed are methods for producing hydrocarbons from a subterranean reservoir. The methods comprise penetrating the subterranean reservoir with a plurality of well pairs that are laterally displaced across a well pad in an array. The methods further comprise operating the plurality of well pairs under a first set of conditions that induce a solvent-concentration gradient, a temperature gradient, or a combination thereof within the subterranean reservoir by: (i) injecting varying concentrations of steam, solvent, or combinations thereof across the array, and (ii) producing hydrocarbons from the reservoir via the plurality of well pairs. The methods further comprise operating the plurality of well pairs under a second set of conditions that delocalize the solvent-concentration gradient, the temperature gradient, or the combination thereof across the array to enhance hydrocarbon production.
