Abstract
Systems and methods are provided for producing hydrocarbons from reservoirs. A provided method includes drilling a first horizontal well substantially proximate to a base of a reservoir and drilling a second horizontal well at a horizontal offset from the first horizontal well. Fluid communication is established between the first horizontal well and the second horizontal well through cyclic production processes. A vertical mobilizing agent is injected into the reservoir and a lateral mobilizing agent is imposed on the reservoir. Fluids are produced from the first horizontal well.
